David Hume

David Hume was a Scottish philosopher, historian, economist and essayist.

Sourced

• A wise man's kingdom is his own breast: or, if he ever looks farther, it will only be to the judgment of a select few, who are free from prejudices, and capable of examining his work. Nothing indeed can be a stronger presumption of falsehood than the approbation of the multitude; and Phocion, you know, always suspected himself of some blunder when he was attended with the applauses of the populace.
  • Playfully ironic letter to Adam Smith regarding the positive reception of "The Theory of Moral Sentiments"

• Does a man of sense run after every silly tale of hobgoblins or fairies, and canvass particularly the evidence? I never knew anyone, that examined and deliberated about nonsense who did not believe it before the end of his enquiries.
  • Letters

• With regard to politics and the character of princes and great men, I think I am very moderate. My views of things are more conformable to Whig principles; my representation of persons to Tory prejudices. Nothing can so much prove that men commonly regard more persons than things, as to find that I am commonly numbered among the Tories.
  • E. C. Mossner, Life of David Hume (Clarendon Press, 2001), p. 311.

• Here am I who have written on all sorts of subjects calculated to excite hostility, moral, political, and religious, and yet I have no enemies — except, indeed, all the Whigs, all the Tories, and all the Christians.

Of The Understanding

• Nothing is more usual and more natural for those, who pretend to discover anything new to the world in philosophy and the sciences, than to insinuate the praises of their own systems, by decrying all those, which have been advanced before them. And indeed were they content with lamenting that ignorance, which we still lie under in the most important questions, that can come before the tribunal of human reason, there are few, who have an acquaintance with the sciences, that would not readily agree with them. 'Tis easy for one of judgment and learning, to perceive the weak foundation even of those systems, which have obtained the greatest credit, and have carried their pretensions highest to accurate and profound reasoning. Principles taken upon trust, consequences lamely deduced from them, want of coherence in the parts, and of evidence in the whole, these are every where to be met with in the systems of the most eminent philosophers, and seem to have drawn disgrace upon philosophy itself.
  • Introduction

• For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe any thing but the perception. When my perceptions are remov’d for any time, as by sound sleep; so long am I insensible of myself, and may truly be said not to exist. And were all my perceptions remov’d by death, and cou’d I neither think, nor feel, nor see, nor love, nor hate after the dissolution of my body, I shou’d be entirely annihilated, nor do I conceive what is farther requisite to make me a perfect non-entity. If any one upon serious and unprejudic’d reflexion, thinks he has a different notion of himself, I must confess I can reason no longer with him. All I can allow him is, that he may be in the right as well as I, and that we are essentially different in this particular. He may, perhaps, perceive something simple and continu’d, which he calls himself; tho’ I am certain there is no such principle in me... But setting aside some metaphysicians of this kind, I may venture to affirm of the rest of mankind, that they are nothing but a bundle or collection of different perceptions, which succeed each other with an inconceivable rapidity, and are in a perpetual flux and movement.
  • Part 4 Of the sceptical and other systems of philosophy, Sect. 6 Of personal identity

• Methinks I am like a man, who having struck on many shoals, and having narrowly escap'd shipwreck in passing a small frith, has yet the temerity to put out to sea in the same leaky weather-beaten vessel, and even carries his ambition so far as to think of compassing the globe under these disadvantageous circumstances.
  • Part 4 Of the sceptical and other systems of philosophy, Sect. 7 Conclusion of this book

• I am first affrighted and confounded with that forelorn solitude, in which I am plac'd in my philosophy, and fancy myself some strange uncouth monster, who not being able to mingle and unite in society, has been expell'd all human commerce, and left utterly abandon'd and disconsolate. Fain wou'd I run into the crowd for shelter and warmth; but cannot prevail with myself to mix with such deformity. I call upon others to join me, in order to make a company apart; but no one will hearken to me. Every one keeps at a distance, and dreads that storm, which beats upon me from every side. I have expos'd myself to the enmity of all metaphysicians, logicians, mathematicians, and even theologians; and can I wonder at the insults I must suffer? I have declar'd my disapprobation of their systems; and can I be surpriz'd, if they shou'd express a hatred of mine and of my person? When I look abroad, I foresee on every side, dispute, contradiction, anger, calumny and detraction. When I turn my eye inward, I find nothing but doubt and ignorance. All the world conspires to oppose and contradict me; tho' such is my weakness, that I feel all my opinions loosen and fall of themselves, when unsupported by the approbation of others. Every step I take is with hesitation, and every new reflection makes me dread an error and absurdity in my reasoning.
  For with what confidence can I venture upon such bold enterprises, when beside those numberless infirmities peculiar to myself, I find so many which are common to human nature? Can I be sure, that in leaving all established opinions I am following truth; and by what criterion shall I distinguish her, even if fortune shou'd at last guide me on her foot-steps? After the most accurate and exact of my reasonings, I can give no reason why I shou'd assent to it; and feel nothing but a strong propensity to consider objects strongly in that view, under which they appear to me. Experience is a principle, which instructs me in the several conjunctions of objects for the past. Habit is another principle, which determines me to expect the same for the future; and both of them conspiring to operate upon the imagination, make me form certain ideas in a more intense and lively manner, than others, which are not attended with the same advantages. Without this quality, by which the mind enlivens some ideas beyond others (which seemingly is so trivial, and so little founded on reason) we cou'd never assent to any argument, nor carry our view beyond those few objects, which are present to our senses. Nay, even to these objects we cou'd never attribute any existence, but what was dependent on the senses; and must comprehend them entirely in that succession of perceptions, which constitutes our self or person. Nay farther, even with relation to that succession, we cou'd only admit of those perceptions, which are immediately present to our consciousness, nor cou'd those lively images, with which the memory presents us, be ever receiv'd as true pictures of past perceptions. The memory, senses, and understanding are, therefore, all of them founded on the imagination, or the vivacity of our ideas.
  • Part 4 Of the sceptical and other systems of philosophy, Sect. 7 Conclusion of this book

• This deficiency in our ideas is not, indeed, perceived in common life, nor are we sensible, that in the most usual conjunctions of cause and effect we are as ignorant of the ultimate principle, which binds them together, as in the most unusual and extraordinary. But this proceeds merely from an illusion of the imagination; and the question is, how far we ought to yield to these illusions. This question is very difficult, and reduces us to a very dangerous dilemma, whichever way we answer it. For if we assent to every trivial suggestion of the fancy; beside that these suggestions are often contrary to each other; they lead us into such errors, absurdities, and obscurities, that we must at last become asham'd of our credulity. Nothing is more dangerous to reason than the flights of the imagination, and nothing has been the occasion of more mistakes among philosophers. Men of bright fancies may in this respect be compar'd to those angels, whom the scripture represents as covering their eyes with their wings. This has already appear'd in so many instances, that we may spare ourselves the trouble of enlarging upon it any farther.
  • Part 4 Of the sceptical and other systems of philosophy, Sect. 7 Conclusion of this book

• Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous.

Of the Passions

• No quality of human nature is more remarkable, both in itself and in its consequences, than that propensity we have to sympathize with others, and to receive by communication their inclinations and sentiments, however different from, or even contrary to our own. This is not only conspicuous in children, who implicitly embrace every opinion propos’d to them; but also in men of the greatest judgment and understanding, who find it very difficult to follow their own reason or inclination, in opposition to that of their friends and daily companions. To this principle we ought to ascribe the great uniformity we may observe in the humours and turn of thinking of those of the same nation; and ’tis much more probable, that this resemblance arises from sympathy, than from any influence of the soil and climate, which, tho’ they continue invariably the same, are not able to preserve the character of a nation the same for a century together. A good-natur’d man finds himself in an instant of the same humour with his company; and even the proudest and most surly take a tincture from their countrymen and acquaintance. A chearful countenance infuses a sensible complacency and serenity into my mind; as an angry or sorrowful one throws a sudden dump upon me. Hatred, resentment, esteem, love, courage, mirth and melancholy; all these passions I feel more from communication than from my own natural temper and disposition. So remarkable a phaenomenon merits our attention, and must be trac’d up to its first principles.
  • Part 1 Of pride and humility, Sect. 11 Of the love of fame

• We speak not strictly and philosophically when we talk of the combat of passion and of reason. Reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.
  • Part 3 Of the will and direct passions, Sect. 3 Of the influencing motives of the will

• What may at first occur on this head, is, that as nothing can be contrary to truth or reason, except what has a reference to it, and as the judgments of our understanding only have this reference, it must follow, that passions can be contrary to reason only so far as they are accompany'd with some judgment or opinion. According to this principle, which is so obvious and natural, `tis only in two senses, that any affection can be call'd unreasonable. First, When a passion, such as hope or fear, grief or joy, despair or security, is founded on the supposition or the existence of objects, which really do not exist. Secondly, When in exerting any passion in action, we chuse means insufficient for the design'd end, and deceive ourselves in our judgment of causes and effects. Where a passion is neither founded on false suppositions, nor chuses means insufficient for the end, the understanding can neither justify nor condemn it. `Tis not contrary to reason to prefer the destruction of the whole world to the scratching of my finger. `Tis not contrary to reason for me to chuse my total ruin, to prevent the least uneasiness of an Indian or person wholly unknown to me. `Tis as little contrary to reason to prefer even my own acknowledge'd lesser good to my greater, and have a more ardent affection for the former than the latter. A trivial good may, from certain circumstances, produce a desire superior to what arises from the greatest and most valuable enjoyment; nor is there any thing more extraordinary in this, than in mechanics to see one pound weight raise up a hundred by the advantage of its situation. In short, a passion must be accompany'd with some false judgment. in order to its being unreasonable; and even then `tis not the passion, properly speaking, which is unreasonable, but the judgment.

Of Morals

• There is an inconvenience which attends all abstruse reasoning. that it may silence, without convincing an antagonist, and requires the same intense study to make us sensible of its force, that was at first requisite for its invention. When we leave our closet, and engage in the common affairs of life, its conclusions seem to vanish, like the phantoms of the night on the appearance of the morning; and 'tis difficult for us to retain even that conviction, which we had attain'd with difficulty.
  • Part 1 Of virtue and vice in general, Sect. 1 Moral distinctions not deriv'd from reason

• Morality is a subject that interests us above all others: We fancy the peace of society to be at stake in every decision concerning it; and 'tis evident, that this concern must make our speculations appear more real and solid, than where the subject is, in a great measure, indifferent to us. What affects us, we conclude can never be a chimera; and as our passion is engag'd on the one side or the other, we naturally think that the question lies within human comprehension; which, in other cases of this nature, we are apt to entertain some doubt of. Without this advantage I never should have ventur'd upon a third volume of such abstruse philosophy, in an age, wherein the greatest part of men seem agreed to convert reading into an amusement, and to reject every thing that requires any considerable degree of attention to be comprehended.
  • Part 1 Of virtue and vice in general, Sect. 1 Moral distinctions not deriv'd from reason

• Morals excite passions, and produce or prevent actions. Reason of itself is utterly impotent in this particular. The rules of morality, therefore, are not conclusions of our reason.
  • Part 1 Of virtue and vice in general, Sect. 1 Moral distinctions not deriv'd from reason

• Actions may be laudable or blameable; but they cannot be reasonable: Laudable or blameable, therefore, are not the same with reasonable or unreasonable. The merit and demerit of actions frequently contradict, and sometimes controul our natural propensities. But reason has no such influence. Moral distinctions, therefore, are not the offspring of reason. Reason is wholly inactive, and can never be the source of so active a principle as conscience, or a sense of morals.
  • Part 1 Of virtue and vice in general, Sect. 1 Moral distinctions not deriv'd from reason

• Take any action allow’d to be vicious: Wilful murder, for instance. Examine it in all lights, and see if you can find that matter of fact, or real existence, which you call vice. In which-ever way you take it, you find only certain passions, motives, volitions and thoughts. There is no other matter of fact in the case. The vice entirely escapes you, as long as you consider the object. You never can find it, till you turn your reflexion into your own breast, and find a sentiment of disapprobation, which arises in you, towards this action. Here is a matter of fact; but ’tis the object of feeling, not of reason. It lies in yourself, not in the object. So that when you pronounce any action or character to be vicious, you mean nothing, but that from the constitution of your nature you have a feeling or sentiment of blame from the contemplation of it. Vice and virtue, therefore, may be compar’d to sounds, colours, heat and cold, which, according to modern philosophy, are not qualities in objects, but perceptions in the mind[.]

An Enquiry Concerning Human Understanding (1748; 1751)

First published as Philosophical Essays Concerning Human Understanding in 1748, revised in 1751, and retitled in 1758.

• Custom, then, is the great guide of human life. It is that principle alone which renders our experience useful to us, and makes us expect, for the future, a similar train of events with those which have appeared in the past. Without the influence of custom, we should be entirely ignorant of every matter of fact beyond what is immediately present to the memory and senses. We should never know how to adjust means to ends, or to employ our natural powers in the production of any effect. There would be an end at once of all action, as well as of the chief part of speculation.
  • Variant (perhaps a paraphrase of this passage): It is not reason which is the guide of life, but custom.

• Nature has pointed out a mixed kind of life as most suitable to the human race, and secretly admonished them to allow none of these biases to draw too much, so as to incapacitate them for other occupations and entertainments. Indulge your passion for science, says she, but let your science be human, and such as may have a direct reference to action and society. Abstruse thought and profound researches I prohibit, and will severely punish, by the pensive melancholy which they introduce, by the endless uncertainty in which they involve you, and by the cold reception which your pretended discoveries shall meet with, when communicated. Be a philosopher; but, amidst all your philosophy, be still a man.
  • Section 1 : Of The Different Species of Philosophy

• The most perfect philosophy of the natural kind only staves off our ignorance a little longer: as perhaps the most perfect philosophy of the moral or metaphysical kind serves only to discover larger portions of it. Thus the observation of human blindness and weakness is the result of all philosophy, and meets us at every turn, in spite of our endeavours to elude or avoid it.
  • Section 4 : Sceptical Doubts Concerning The Operations of The Understanding

• Though experience be our only guide in reasoning concerning matters of fact; it must be acknowledged, that this guide is not altogether infallible, but in some cases is apt to lead us into errors.
  • Section 10 : Of Miracles Pt. 1

• In our reasonings concerning matter of fact, there are all imaginable degrees of assurance, from the highest certainty to the lowest species of moral evidence. A wise man, therefore, proportions his belief to the evidence.
• ... no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavors to establish.
  • Section 10 : Of Miracles Pt. 1; Variant: A wise man... proportions his belief to the evidence.

• When anyone tells me, that he saw a dead man restored to life, I immediately consider with myself, whether it be more probable, that this person should either deceive or be deceived, or that the fact, which he relates, should really have happened. I weigh the one miracle against the other; and according to the superiority, which I discover, I pronounce my decision, and always reject the greater miracle. If the falsehood of his testimony would be more miraculous, than the event which he relates; then, and not till then, can he pretend to command my belief or opinion.
  • Section 10 : Of Miracles Pt. 1

• Eloquence, when at its highest pitch, leaves little room for reason or reflection; but addressing itself entirely to the fancy or the affections, captivates the willing hearers, and subdues their understanding. Happily, this pitch it seldom attains. But what a Tully or a Demosthenes could scarcely effect over a Roman or Athenian audience, every Capuchin, every itinerant or stationary teacher can perform over the generality of mankind, and in a higher degree, by touching such gross and vulgar passions.
  • Section 10 : Of Miracles Pt. 2

• The Christian Religion not only was at first attended with miracles, but even at this day cannot be believed by any reasonable person without one. Mere reason is insufficient to convince us of its veracity: and whoever is moved by Faith to assent to it, is conscious of a continued miracle in his own person, which subverts all the principles of his understanding, and gives him a determination to believe what is most contrary to custom and experience.
  • Section 10 : Of Miracles Pt. 2

• When we run over libraries, persuaded of these principles, what havoc must we make? If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning concerning matter of fact and existence? No. Commit it then to the flames: For it can contain nothing but sophistry and illusion.
  • Section 12 : Of the Academical or Sceptical Philosophy Pt. 3

An Enquiry Concerning the Principles of Morals (1751)

• In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind. If any false opinion, embraced from appearances, has been found to prevail; as soon as farther experience and sounder reasoning have given us juster notions of human affairs, we retract our first sentiment, and adjust anew the boundaries of moral good and evil.

The Natural History of Religion (1757)

This work first appeared in the collection of essays Four Dissertations (1757). It was republished several times during Hume's life with minor variations.

• As every enquiry, which regards religion, is of the utmost importance, there are two questions in particular, which challenge our attention, to wit, that concerning its foundation in reason, and that concerning its origin in human nature. Happily, the first question, which is the most important, admits of the most obvious, at least, the clearest, solution. The whole frame of nature bespeaks an intelligent author; and no rational enquirer can, after serious reflection, suspend his belief a moment with regard to the primary principles of genuine Theism and Religion. But the other question, concerning the origin of religion in human nature, is exposed to some more difficulty. The belief of invisible, intelligent power has been very generally diffused over the human race, in all places and in all ages; but it has neither perhaps been so universal as to admit of no exception, nor has it been, in any degree, uniform in the ideas, which it has suggested. Some nations have been discovered, who entertained no sentiments of Religion, if travellers and historians may be credited; and no two nations, and scarce any two men, have ever agreed precisely in the same sentiments.
  • Introduction

• That original intelligence, say the MAGIANS, who is the first principle of all things, discovers himself immediately to the mind and understanding alone; but has placed the sun as his image in the visible universe; and when that bright luminary diffuses its beams over the earth and the firmament, it is a faint copy of the glory which resides in the higher heavens. If you would escape the displeasure of this divine being, you must be careful never to set your bare foot upon the ground, nor spit into a fire, nor throw any water upon it, even though it were consuming a whole city. Who can express the perfections of the Almighty? say the Mahometans. Even the noblest of his works, if compared to him, are but dust and rubbish. How much more must human conception fall short of his infinite perfections? His smile and favour renders men for ever happy; and to obtain it for your children, the best method is to cut off from them, while infants, a little bit of skin, about half the breadth of a farthing. Take two bits of cloth, say the Roman catholics, about an inch or an inch and a half square, join them by the corners with two strings or pieces of tape about sixteen inches long, throw this over your head, and make one of the bits of cloth lie upon your breast, and the other upon your back, keeping them next your skin: There is not a better secret for recommending yourself to that infinite Being, who exists from eternity to eternity.
  • Part VII - Confirmation of this doctrine

• The heroes in paganism correspond exactly to the saints in popery, and holy dervises in MAHOMETANISM. The place of, HERCULES, THESEUS, HECTOR, ROMULUS, is now supplied by DOMINIC, FRANCIS, ANTHONY, and BENEDICT. Instead of the destruction of monsters, the subduing of tyrants, the defence of our native country; whippings and fastings, cowardice and humility, abject submission and slavish obedience, are become the means of obtaining celestial honours among mankind.
  • Part X - With regard to courage or abasement

• To oppose the torrent of scholastic religion by such feeble maxims as these, that it is impossible for the same thing to be and not to be, that the whole is greater than a part, that two and three make five; is pretending to stop the ocean with a bullrush. Will you set up profane reason against sacred mystery? No punishment is great enough for your impiety. And the same fires, which were kindled for heretics, will serve also for the destruction of philosophers.
  • Part XI - With regard to reason or absurdity

• How can you worship leeks and onions? we shall suppose a SORBONNIST to say to a priest of SAIS. If we worship them, replies the latter; at least, we do not, at the same time, eat them. But what strange object of adoration are cats and monkeys? says the learned doctor. They are at least as good as the relics or rotten bones of martyrs, answers his no less learned antagonist. Are you not mad, insists the Catholic, to cut one another's throat about the preference of a cabbage or a cucumber? Yes, says the pagan; I allow it, if you will confess, that those are still madder, who fight about the preference among volumes of sophistry, ten thousand of which are not equal in value to one cabbage or cucumber.
  • Part XII - With regard to doubt or conviction

• We may observe, that, notwithstanding the dogmatical, imperious style of all superstition, the conviction of the religionists, in all ages, is more affected than real, and scarcely ever approaches, in any degree, to that solid belief and persuasion, which governs us in the common affairs of life. Men dare not avow, even to their own hearts, the doubts which they entertain on such subjects: They make a merit of implicit faith; and disguise to themselves their real infidelity, by the strongest asseverations and most positive bigotry. But nature is too hard for all their endeavours, and suffers not the obscure, glimmering light, afforded in those shadowy regions, to equal the strong impressions, made by common sense and by experience. The usual course of men's conduct belies their words, and shows, that their assent in these matters is some unaccountable operation of the mind between disbelief and conviction, but approaching much nearer to the former than to the latter.
  • Part XII - With regard to doubt or conviction

• And any practice, recommended to him, which either serves to no purpose in life, or offers the strongest violence to his natural inclinations; that practice he will the more readily embrace, on account of those very circumstances, which should make him absolutely reject it. It seems the more purely religious, because it proceeds from no mixture of any other motive or consideration. And if, for its sake, he sacrifices much of his ease and quiet, his claim of merit appears still to rise upon him, in proportion to the zeal and devotion which he discovers. In restoring a loan, or paying a debt, his divinity is nowise beholden to him; because these acts of justice are what he was bound to perform, and what many would have performed, were there no god in the universe. But if he fast a day, or give himself a sound whipping; this has a direct reference, in his opinion, to the service of God. No other motive could engage him to such austerities. By these distinguished marks of devotion, he has now acquired the divine favour; and may expect, in recompence, protection and safety in this world, and eternal happiness in the next.
  • Part XIV - Bad influence of popular religions on morality

• The more exquisite any good is, of which a small specimen is afforded us, the sharper is the evil, allied to it; and few exceptions are found to this uniform law of nature. The most sprightly wit borders on madness; the highest effusions of joy produce the deepest melancholy; the most ravishing pleasures are attended with the most cruel lassitude and disgust; the most flattering hopes make way for the severest disappointments. And, in general, no course of life has such safety (for happiness is not to be dreamed of) as the temperate and moderate, which maintains, as far as possible, a mediocrity, and a kind of insensibility, in every thing. As the good, the great, the sublime, the ravishing are found eminently in the genuine principles of theism; it may be expected, from the analogy of nature, that the base, the absurd, the mean, the terrifying will be equally discovered in religious fictions and chimeras.
  • Part XV - General corollary

• The universal propensity to believe in invisible, intelligent power, if not an original instinct, being at least a general attendant of human nature, may be considered as a kind of mark or stamp, which the divine workman has set upon his work; and nothing surely can more dignify mankind, than to be thus selected from all other parts of the creation, and to bear the image or impression of the universal Creator. But consult this image, as it appears in the popular religions of the world. How is the deity disfigured in our representations of him! What caprice, absurdity, and immorality are attributed to him! How much is he degraded even below the character, which we should naturally, in common life, ascribe to a man of sense and virtue!
  • Part XV - General corollary

• What a noble privilege is it of human reason to attain the knowledge of the supreme Being; and, from the visible works of nature, be enabled to infer so sublime a principle as its supreme Creator? But turn the reverse of the medal. Survey most nations and most ages. Examine the religious principles, which have, in fact, prevailed in the world. You will scarcely be persuaded, that they are any thing but sick men's dreams: Or perhaps will regard them more as the playsome whimsies of monkies in human shape, than the serious, positive, dogmatical asseverations of a being, who dignifies himself with the name of rational.
  • Part XV - General corollary

• Hear the verbal protestations of all men: Nothing so certain as their religious tenets. Examine their lives: You will scarcely think that they repose the smallest confidence in them. The greatest and truest zeal gives us no security against hypocrisy: The most open impiety is attended with a secret dread and compunction. No theological absurdities so glaring that they have not, sometimes, been embraced by men of the greatest and most cultivated understanding. No religious precepts so rigorous that they have not been adopted by the most voluptuous and most abandoned of men.
  • Part XV - General corollary

• Ignorance is the mother of Devotion: A maxim that is proverbial, and confirmed by general experience. Look out for a people, entirely destitute of religion: If you find them at all, be assured, that they are but few degrees removed from brutes. What so pure as some of the morals, included in some theological system? What so corrupt as some of the practices, to which these systems give rise?
  • Part XV - General corollary

• The whole is a riddle, an aenigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of our most accurate scrutiny, concerning this subject. But such is the frailty of human reason, and such the irresistible contagion of opinion, that even this deliberate doubt could scarcely be upheld; did we not enlarge our view, and opposing one species of superstition to another, set them a quarrelling; while we ourselves, during their fury and contention, happily make our escape, into the calm, though obscure, regions of philosophy.
  • Part XV - General corollary

Essays Moral, Political, Literary (1741-2; 1748)

• It is a very comfortable reflection to the lovers of liberty, that this peculiar privilege of Britain is of a kind that cannot easily be wrested from us, but must last as long as our government remains, in any degree, free and independent. It is seldom, that liberty of any kind is lost all at once. Slavery has so frightful an aspect to men accustomed to freedom, that it must steal upon them by degrees, and must disguise itself in a thousand shapes, in order to be received. But, if the liberty of the press ever be lost, it must be lost at once. The general laws against sedition and libelling are at present as strong as they possibly can be made. Nothing can impose a farther restraint, but either the clapping an Imprimatur upon the press, or the giving to the court very large discretionary powers to punish whatever displeases them. But these concessions would be such a bare-faced violation of liberty, that they will probably be the last efforts of a despotic government. We may conclude, that the liberty of Britain is gone for ever when these attempts shall succeed.
  • Essay 2 : Of the Liberty of the Press (early editions)

• Nothing appears more surprising to those, who consider human affairs with a philosophical eye, than the easiness with which the many are governed by the few; and the implicit submission, with which men resign their own sentiments and passions to those of their rulers. When we enquire by what means this wonder is effected, we shall find, that, as Force is always on the side of the governed, the governors have nothing to support them but opinion. It is therefore, on opinion only that government is founded; and this maxim extends to the most despotic and most military governments, as well as to the most free and most popular.
  • Essay 4 : Of The First Principles of Government

• It is, therefore, a just political maxim, that every man must be supposed a knave: Though at the same time, it appears somewhat strange, that a maxim should be true in politics, which is false in fact. But to satisfy us on this head, we may consider, that men are generally more honest in their private than in their public capacity, and will go greater lengths to serve a party, than when their own private interest is alone concerned. Honour is a great check upon mankind: But where a considerable body of men act together, this check is, in a great measure, removed; since a man is sure to be approved of by his own party, for what promotes the common interest; and he soon learns to despise the clamours of adversaries.

• In all ages of the world, priests have been enemies to liberty; and it is certain, that this steady conduct of theirs must have been founded on fixed reasons of interest and ambition. Liberty of thinking, and of expressing our thoughts, is always fatal to priestly power, and to those pious frauds, on which it is commonly founded; and, by an infallible connexion, which prevails among all kinds of liberty, this privilege can never be enjoyed, at least has never yet been enjoyed, but in a free government.

• The slaving Poor are incapable of any Principles: Gentlemen may be converted to true Principles, by Time and Experience. The middling Rank of Men have Curiosity and Knowledge enough to form Principles, but not enough to form true ones, or correct any Prejudices that they may have imbib’d: And ’tis among the middling Rank, that Tory Principles do at present prevail most in England.

• Avarice, the spur of industry, is so obstinate a passion, and works its way through so many real dangers and difficulties, that it is not likely to be scared by an imaginary danger, which is so small, that it scarcely admits of calculation. Commerce, therefore, in my opinion, is apt to decay in absolute governments, not because it is there less secure, but because it is less honourable.
  • Essay 12 : Of Civil Liberty

• It is a great mortification to the vanity of man, that his utmost art and industry can never equal the meanest of nature's productions, either for beauty or value. Art is only the under-workman, and is employed to give a few strokes of embellishment to those pieces, which come from the hand of the master

  • Essay 15 : The Epicurean

• If nature has been frugal in her gifts and endowments, there is the more need of art to supply her defects. If she has been generous and liberal, know that she still expects industry and application on our part, and revenges herself in proportion to our negligent ingratitude. The richest genius, like the most fertile soil, when uncultivated, shoots up into the rankest weeds; and instead of vines and olives for the pleasure and use of man, produces, to its slothful owner, the most abundant crop of poisons.

• All sentiment is right; because sentiment has a reference to nothing beyond itself, and is always real, wherever a man is conscious of it. But all determinations of the understanding are not right; because they have a reference to something beyond themselves, to wit, real matter of fact; and are not always conformable to that standard.
  • Essay 23 : Of The Standard of Taste

• Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty. One person may even perceive deformity, where another is sensible of beauty; and every individual ought to acquiesce in his own sentiment, without pretending to regulate those of others.

The History of England (1754-62)

• It was a fixed maxim in this reign, as well as in some of the subsequent, that no native of the island should ever be advanced to any dignity, ecclesiastical, civil, or military. The king therefore, upon Stigand’s deposition, promoted Lanfranc, a Milanese monk, celebrated for his learning and piety, to the vacant see. This prelate was rigid in defending the prerogatives of his station; and after a long process before the pope, he obliged Thomas, a Norman monk, who had been appointed to the see of York, to acknowledge the primacy of the archbishop of Canterbury. Where ambition can be so happy as to cover its enterprizes, even to the person himself, under the appearance of principle, it is the most incurable and inflexible of all human passions. Hence Lanfranc’s zeal in promoting the interests of the papacy, by which he himself augmented his own authority, was indefatigable; and met with proportionable success. The devoted attachment to Rome continually encreased in England; and being favoured by the sentiments of the conquerors, as well as by the monastic establishments formerly introduced by Edred and by Edgar, it soon reached the same height, at which it had, during some time, stood in France and Italy. It afterwards went much farther; being favoured by that very remote situation, which had at first obstructed its progress; and being less checked by knowledge and a liberal education, which were still somewhat more common in the southern countries.

Four Dissertations (1757)

Of the Standard of Taste

• The sentiments of men often differ with regard to beauty and deformity of all kinds, even while their general discourse is the same ... In all matters of opinion and science, the case is opposite: The difference among men is there oftener found to lie in generals than in particulars; and to be less in reality than in appearance.

• It is natural for us to seek a Standard of Taste; a rule, by which the various sentiments of men may be reconciled; at least, a decision, afforded, confirming one sentiment, and condemning another.

• But though all the general rules of art are founded only on experience and on the observation of the common sentiments of human nature, we must not imagine, that, on every occasion, the feelings of men will be conformable to these rules.

• But though there be naturally a wide difference in point of delicacy between one person and another, nothing tends further to encrease and improve this talent, than practice in a particular art, and the frequent survey or contemplation of a particular species of beauty.

• The same good sense, that directs men in the ordinary occurrences of life, is not hearkened to in religious matters, which are supposed to be placed altogether above the cognizance of human reason.

Dialogues concerning Natural Religion (1779)

Written sporadically from 1757-1776 and published posthumously.

• What peculiar privilege has this little agitation of the brain which we call thought, that we must thus make it the model of the whole universe? Our partiality in our own favour does indeed present it on all occasions; but sound philosophy ought carefully to guard against so natural an illusion.
  • Philo to Cleanthes, Part II

• If reason (I mean abstract reason, derived from inquiries a priori) be not alike mute with regard to all questions concerning cause and effect, this sentence at least it will venture to pronounce, That a mental world, or universe of ideas, requires a cause as much, as does a material world, or universe of objects; and, if similar in its arrangement, must require a similar cause. For what is there in this subject, which should occasion a different conclusion or inference? In an abstract view, they are entirely alike; and no difficulty attends the one supposition, which is not common to both of them.
  • Philo to Cleanthes, Part IV

• In a word, CLEANTHES, a man who follows your hypothesis is able perhaps to assert, or conjecture, that the universe, sometime, arose from something like design: but beyond that position he cannot ascertain one single circumstance; and is left afterwards to fix every point of his theology by the utmost license of fancy and hypothesis. This world, for aught he knows, is very faulty and imperfect, compared to a superior standard; and was only the first rude essay of some infant deity, who afterwards abandoned it, ashamed of his lame performance: it is the work only of some dependent, inferior deity; and is the object of derision to his superiors: it is the production of old age and dotage in some superannuated deity; and ever since his death, has run on at adventures, from the first impulse and active force which it received from him. You justly give signs of horror, DEMEA, at these strange suppositions; but these, and a thousand more of the same kind, are CLEANTHES’s suppositions, not mine. From the moment the attributes of the Deity are supposed finite, all these have place. And I cannot, for my part, think that so wild and unsettled a system of theology is, in any respect, preferable to none at all.
  • Philo to Demea, Part V

• You need only look around you, replied PHILO, to satisfy yourself with regard to this question. A tree bestows order and organisation on that tree which springs from it, without knowing the order; an animal in the same manner on its offspring; a bird on its nest; and instances of this kind are even more frequent in the world than those of order, which arise from reason and contrivance. To say, that all this order in animals and vegetables proceeds ultimately from design, is begging the question; nor can that great point be ascertained otherwise than by proving, a priori, both that order is, from its nature, inseparably attached to thought; and that it can never of itself, or from original unknown principles, belong to matter.
  • Philo to Demea, Part VII

• In such a chain, too, or succession of objects, each part is caused by that which preceded it, and causes that which succeeds it. Where then is the difficulty? But the WHOLE, you say, wants a cause. I answer, that the uniting of these parts into a whole, like the uniting of several distinct countries into one kingdom, or several distinct members into one body, is performed merely by an arbitrary act of the mind, and has no influence on the nature of things. Did I shew you the particular causes of each individual in a collection of twenty particles of matter, I should think it very unreasonable, should you afterwards ask me, what was the cause of the whole twenty. This is sufficiently explained in explaining the cause of the parts.
  • Cleanthes to Demea, Part IX

• And why should man, added he, pretend to an exemption from the lot of all other animals? The whole earth, believe me, PHILO, is cursed and polluted. A perpetual war is kindled amongst all living creatures. Necessity, hunger, want, stimulate the strong and courageous: Fear, anxiety, terror, agitate the weak and infirm. The first entrance into life gives anguish to the new-born infant and to its wretched parent: Weakness, impotence, distress, attend each stage of that life: and it is at last finished in agony and horror.
  • Demea to Philo, Part X

• Were a stranger to drop on a sudden into this world, I would show him, as a specimen of its ills, a hospital full of diseases, a prison crowded with malefactors and debtors, a field of battle strewed with carcasses, a fleet foundering in the ocean, a nation languishing under tyranny, famine, or pestilence. To turn the gay side of life to him, and give him a notion of its pleasures; whither should I conduct him? to a ball, to an opera, to court? He might justly think, that I was only showing him a diversity of distress and sorrow.
  • Demea to Philo, Part X

• Look round this universe. What an immense profusion of beings, animated and organised, sensible and active! You admire this prodigious variety and fecundity. But inspect a little more narrowly these living existences, the only beings worth regarding. How hostile and destructive to each other! How insufficient all of them for their own happiness! How contemptible or odious to the spectator! The whole presents nothing but the idea of a blind Nature, impregnated by a great vivifying principle, and pouring forth from her lap, without discernment or parental care, her maimed and abortive children!
  • Philo to Cleanthes, Part XI

• If the whole of natural theology, as some people seem to maintain, resolves itself into one simple, though somewhat ambiguous, at least undefined proposition, that the cause or causes of order in the universe probably bear some remote analogy to human intelligence: If this proposition be not capable of extension, variation, or more particular explication: If it affords no inference that affects human life, or can be the source of any action or forbearance: And if the analogy, imperfect as it is, can be carried no farther than to the human intelligence, and cannot be transferred, with any appearance of probability, to the other qualities of the mind; if this really be the case, what can the most inquisitive, contemplative, and religious man do more than give a plain, philosophical assent to the proposition, as often as it occurs, and believe that the arguments on which it is established exceed the objections which lie against it?
  • Philo to Cleanthes, Part XII

• God's power is infinite. Whatever he wills is executed. But neither man, nor any other animal, is happy. Therefore he does not will their happiness. Epicurus' old questions are yet unanswered. Is God willing to prevent evil, but unable? Then is he impotent. Is he able, but not willing? Then is he malevolent. Is he both able and willing? Whence then is evil?

• It were better, never to look beyond the present material world. By supposing it to contain the principle of its order within itself, we really assert it to be God; and the sooner we arrive at that divinity, the better.
