Scottish Enlightenment philosopher, historian, economist, librarian and essayist
David Hume (7 May 1711 – 25 August 1776) was a Scottish Enlightenment philosopher, historian, economist, librarian and essayist, who is best known today for his highly influential system of philosophical empiricism, skepticism, and naturalism. Beginning with A Treatise of Human Nature (1739–40), Hume strove to create a naturalistic science of man that examined the psychological basis of human nature. Hume argued against the existence of innate ideas, positing that all human knowledge derives solely from experience. This places him with Francis Bacon, Thomas Hobbes, John Locke, and George Berkeley as a British Empiricist.
Hume argued that inductive reasoning and belief in causality cannot be justified rationally; instead, they result from custom and mental habit. We never actually perceive that one event causes another but only experience the "constant conjunction" of events. This problem of induction means that to draw any causal inferences from past experience, it is necessary to presuppose that the future will resemble the past, a presupposition which cannot itself be grounded in prior experience.
An opponent of philosophical rationalists, Hume held that passions rather than reason govern human behaviour, famously proclaiming that "Reason is, and ought only to be the slave of the passions." Hume was also a sentimentalist who held that ethics are based on emotion or sentiment rather than abstract moral principle. He maintained an early commitment to naturalistic explanations of moral phenomena and is usually taken to have first clearly expounded the is–ought problem, or the idea that a statement of fact alone can never give rise to a normative conclusion of what ought to be done.
Hume also denied that humans have an actual conception of the self, positing that we experience only a bundle of sensations, and that the self is nothing more than this bundle of causally-connected perceptions. Hume's compatibilist theory of free will takes causal determinism as fully compatible with human freedom. His views on philosophy of religion, including his rejection of miracles and the argument from design for God's existence, were especially controversial for their time.
Hume influenced utilitarianism, logical positivism, the philosophy of science, early analytic philosophy, cognitive science, theology, and many other fields and thinkers. Immanuel Kant credited Hume as the inspiration who had awakened him from his "dogmatic slumbers."
The gazing populace receive greedily, without examination, whatever soothes superstition and promotes wonder.
The whole is a riddle, an enigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of ourmost 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.
No advantages in this world are pure and unmixed.
The unhappy of all men is he who believes himself to be so.
Poets themselves, tho' liars by profession, always endeavour to give an air of truth to their fictions.
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.
Let us become thoroughly sensible of the weakness, blindness, and narrow limits of human reason: Let us duly consider its uncertainty and endless contrarieties, even in subjects of common life and practice.... When these topics are displayed in their full light, as they are by some philosophers and almost all divines; who can retain such confidence in this frail faculty of reason as to pay any regard to its determinations in points so sublime, so abstruse, so remote from common life and experience?
The heights of popularity and patriotism are still the beaten road to power and tyranny.
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.
Mankind are always found prodigal both of blood and treasure in the maintenance of public justice.
I cannot but bless the memory of Julius Caesar, for the great esteem he expressed for fat men and his aversion to lean ones.
It seems certain, that though a man, in a flush of humour, after intense reflection on the many contradictions and imperfections of human reason, may entirely renounce all belief and opinion, it is impossible for him to persevere in this total scepticism, or make it appear in his conduct for a few hours.
'Tis certain that a serious attention to the sciences and liberal arts softens and humanizes the temper, and cherishes those fine emotions in which true virtue and honor consist. It rarely, very rarely happens that a man of taste and learning is not, at least, an honest man, whatever frailties may attend him.
While Newton seemed to draw off the veil from some of the mysteries of nature, he showed at the same time the imperfections of the mechanical philosophy; and thereby restored her ultimate secrets to that obscurity, in which they ever did and ever will remain.
Absolute monarchy,... is the easiest death, the true Euthanasia of the BRITISH constitution.
If we confine ourselves to a general and distant reflection on the ills of human life, that can have no effect to prepare us for them. If by close and intense meditation we render them present and intimate to us, that is the true secret for poisoning all our pleasures, and rendering us perpetually miserable.
I shall venture to affirm, that there never was a popular religion, which represented the state of departed souls in such a light,as would render it eligible for human kind, that there should be such a state. These fine models of religion are the mere product of philosophy. For as death lies between the eye and the prospect of futurity, that event is so shocking to nature, that it must throw a gloom on all the regions which lie beyond it; and suggest to the generality of mankind the idea of Cerberus and Furies; devils, and torrents of fire and brimstone.
It affords a violent prejudice against almost every science, that no prudent man, however sure of his principles, dares prophesy concerning any event, or foretell the remote consequences of things.
It is with books as with women, where a certain plainness of manner and of dress is more engaging than that glare of paint and airs and apparel which may dazzle the eye, but reaches not the affections.
In all matters of opinion and science ... the difference between men is ... oftener found to lie in generals than in particulars; and to be less in reality than in appearance. An explication of the terms commonly ends the controversy, and the disputants are surprised to find that they had been quarrelling, while at bottom they agreed in their judgement.
Such a superiority do the pursuits of literature possess above every other occupation, that even he who attains but a mediocrity in them, merits the pre-eminence above those that excel the most in the common and vulgar professions.
How can we satisfy ourselves without going on in infinitum? And, after all, what satisfaction is there in that infinite progression? Let us remember the story of the Indian philosopher and his elephant. It was never more applicable than to the present subject. If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world.
Enthusiasm produces the most cruel disorders in human society; but its fury is like that of thunder and tempest, which exhaust themselves in a little time, and leave the air more calm and serene than before.
Reasoning from the common course of nature, and without supposing any new interposition of the Supreme Cause, which ought always to be excluded from philosophy; what is incorruptible must also be ingenerable. The soul, therefore, if immortal, existed before our birth: And if the former existence noways concerned us, neither will the latter.
And indeed nothing but the most determined scepticism, along with a great degree of indolence, can justify this aversion to metaphysics. For if truth be at all within the reach of human capacity, it is certain it must lie very deep and abstruse: and to hope we shall arrive at it without pains, while the greatest geniuses have failed with the utmost pains, must certainly be esteemed sufficiently vain and presumptuous. I pretend to no such advantage in the philosophy I am going to unfold, and would esteem it a strong presumption against it, were it so very easy and obvious.
There has been a controversy started of late, much better worth examination, concerning the general foundation of Morals; whether they be derived from Reason, or from Sentiment; whether we attain the knowledge of them by a chain of argument and induction, or by an immediate feeling and finer internal sense; whether, like all sound judgement of truth and falsehood, they should be the same to every rational intelligent being; or whether, like the perception of beauty and deformity, they be founded entirely on the particular fabric and constitution of the human species.
When I think of God, when I think of him as existent, and when I believe him to be existent, my idea of him neither increases nordiminishes. But as it is certain there is a great difference betwixt the simple conception of the existence of an object, and the belief of it, and as this difference lies not in the parts or composition of the idea which we conceive; it follows, that it must lie in the manner in which we conceive it.
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.
In ancient times, bodily strength and dexterity, being of greater use and importance in war, was also much more esteemed and valued, than at present. ... In short, the different ranks of men are, in a great measure, regulated by riches.
Human Nature is the only science of man; and yet has been hitherto the most neglected.
There is an universal tendency among mankind to conceive all beings like themselves, and to transfer to every object, those qualities, with which they are familiarly acquainted, and of which they are intimately conscious. We find human faces in the moon, armies in the clouds; and by a natural propensity, if not corrected by experience and reflection, ascribe malice or good-will to every thing, that hurts or pleases us.
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.
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.
Barbarity, caprice; these qualities, however nominally disguised, we may universally observe from the ruling character of the deity in all regular religions.
We have no other notion of cause and effect, but that of certain objects, which have always conjoin'd together, and which in all past instances have been found inseparable. We cannot penetrate into the reason of the conjunction. We only observe the thing itself, and always find that from the constant conjunction the objects acquire an union in the imagination.
And what is the greatest number? Number one.
Among well bred people a mutual deference is affected, contempt for others is disguised; authority concealed; attention given to each in his turn; and an easy stream of conversation maintained without vehemence, without interruption, without eagerness for victory, and without any airs of superiority.
Your corn is ripe today; mine will be so tomorrow. 'Tis profitable for us both, that I should labour with you today, and that you should aid me tomorrow.
All inferences from experience... are effects of custom, not of reasoning.
Every wise, just, and mild government, by rendering the condition of its subjects easy and secure, will always abound most in people, as well as in commodities and riches.
Generally speaking, the errors in religion are dangerous; those in philosophy only ridiculous.
This avidity alone, of acquiring goods and possessions for ourselves and our nearest friends, is insatiable, perpetual, universal, and directly destructive of society.
When I turn my eye inward, I find nothing but doubt and ignorance. All the world conspires to oppose and contradict me; though such is my weakness, that I feel all my opinions loosen and fall of themselves, when unsupported by the approbation of others.
An established government has an infinite advantage, by that very circumstance of its being established--the bulk of mankind being governed by authority, not reason, and never attributing authority to anything that has not the recommendation of antiquity.
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.
Avarice, the spur of industry.
What a peculiar privilege has this little agitation of the brain which we call 'thought'.
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.
The identity that we ascribe to things is only a fictitious one, established by the mind, not a peculiar nature belonging to what we’re talking about.
The first ideas of religion arose, not from contemplation of the works of nature, but from a concern with regard to the events of life.
The simplest and most obvious cause which can there be assigned for any phenomena, is probably the true one.
From causes which appear similar, we expect similar effects. This is the sum total of all our experimental conclusions.
Scholastic learning and polemical divinity retarded the growth of all true knowledge.
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.
I say then, that belief is nothing but a more vivid, lively, forcible, firm, steady conception of an object, than what the imagination alone is ever able to attain. This variety of terms, which may seem so unphilosophical, is intended only to express that act of the mind, which renders realities, or what is taken for such, more present to us than fictions, causes them to weigh more in the thought, and gives them a superior influence on the passions and imagination.
The best taxes are such as are levied upon consumptions, especially those of luxury; because such taxes are least felt by the people. They seem, in some measure, voluntary; since a man may choose how far he will use the commodity: They naturally produce sobriety and frugality, if judiciously imposed: And being confounded with the natural price of the commodity, they are scarcely perceived by the consumers. Their only disadvantage is that they are expensive in the levying.
Enthusiasm, being the infirmity of bold and ambitious tempers, is naturally accompanied with a spirit of liberty; as superstition,on the contrary, renders men tame and abject, and fits them for slavery.
In a vain man, the smallest spark may kindle into the greatest flame, because the materials are always prepared for it.
The most pernicious of all taxes are the arbitrary.
It forms a strong presumption against all supernatural and miraculous relations, that they are observed chiefly to abound among ignorant and barbarous nations; or if a civilized people has ever given admission to any of them, that people will be found to have received them from ignorant and barbarous ancestors.
Any person seasoned with a just sense of the imperfections of natural reason, will fly to revealed truth with the greatest avidity.
Moving from an objective statement of fact to a subjective statement of value does not work, because it leaves open questions that have not been answered.
Berkeley , Hume, Kant , Fichte , Hegel , James , Bergson all are united in one earnest attempt, the attempt to reinstate man with his high spiritual claims in a place of importance in the cosmic scheme.
Of all sciences there is none where first appearances are more deceitful than in politics.
The richest genius, like the most fertile soil, when uncultivated, shoots up into the rankest weeds.
... superstitions, which, being unable to defend themselves on fair ground, raise these intangling brambles to cover and protect their weakness. Chased from the open country, these robbers fly into the forest, and lie in wait to break in upon every unguarded avenue of the mind, and overwhelm it with religious fears and prejudices. ... The idea of God, as meaning an infinitely intelligent, wise and good Being, arises from reflecting on the operations of our own mind, and augmenting, without limit, those qualities of goodness and wisdom.
Nothing is so improving to the temper as the study of the beauties either of poetry, eloquence, music, or painting.
Heroism, or military glory, is much admired by the generality of mankind. They consider it as the most sublime kind of merit. Menof cool reflection are not so sanguine in their praises of it.
The more tremendous the divinity is represented, the more tame and submissive do men become his ministers: And the more unaccountable the measures of acceptance required by him, the more necessary does it become to abandon our natural reason, and yield to their ghostly guidance and direction.
Anything that is conceivable is possible.
No man ever threw away life while it was worth keeping.
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.
Mankind are so much the same, in all times and places, that history informs us of nothing new or strange in this particular. Its chief use is only to discover the constant and universal principles of human nature.
The rules of morality are not the conclusion of our reason.
Great pleasures are much less frequent than great pains.
