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."
Custom is the great guide to human life.
We learn the influence of our will from experience alone. And experience only teaches us, how one event constantly follows another; without instructing us in the secret connexion, which binds them together, and renders them inseparable.
Praise never gives us much pleasure unless it concur with our own opinion, and extol us for those qualities in which we chiefly excel.
Of all the animals with which this globe is peopled, there is none towards whom nature seems, at first sight, to have exercised more cruelty than towards man, in the numberless wants and necessities with which she has loaded him, and in the slender means which she affords to the relieving these necessities.

No human testimony can have such force as to prove a miracle, and make it a just foundation for any such system of religion
The heights of popularity and patriotism are still the beaten road to power and tyranny; flattery to treachery; standing armies to arbitrary government; and the glory of God to the temporal interest of the clergy.
The supposition that the future resembles the past, is not founded on arguments of any kind, but is derived entirely from habit.
No truth appears to me more evident than that beasts are endowed with thought and reason as well as men.
A miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience can possibly be imagined.
When suicide is out of fashion we conclude that none but madmen destroy themselves; and all the efforts of courage appear chimerical to dastardly minds ... Nevertheless, how many instances are there, well attested, of men, in every other respect perfectly discreet, who, without remorse, rage, or despair, have quitted life for no other reason than because it was a burden to them, and have died with more composure than they lived?
Apart from the representational content of an idea there is another component: its force and vivacity, its impetus.
The bigotry of theologians is a malady which seems almost incurable.
To philosopher and historian the madness and imbecile wickedness of mankind ought to appear ordinary events.
The law always limits every power it gives.
Philosophy would render us entirely Pyrrhonian, were not nature too strong for it.
Your corn is ripe today, mine will be so tomorrow. 'Tis profitable for us both that I should labor with you today, and that you should aid me tomorrow. I have no kindness for you, and know you have as little for me. I will not, therefore, take any pains upon your account . . . Here then I leave you to labor alone; you treat me in the same manner. The seasons change, and both of us lose our harvests for want of mutual confidence and security.
We find in the course of nature that though the effects be many, the principles from which they arise are commonly few and simple, and that it is the sign of an unskilled naturalist to have recourse to a different quality in order to explain every different operation.
It is harder to avoid censure than to gain applause; for this may be done by one great or wise action in an age. But to escape censure a man must pass his whole life without saying or doing one ill or foolish thing
Truth is disputable, not human taste.
Superstition is an enemy to civil liberty.
Liberty of any kind is never lost all at once.
There is nothing, in itself, valuable or despicable, desirable or hateful, beautiful or deformed; but that these attributes arise from the particular constitution and fabric of human sentiment and affection.
A man acquainted with history may, in some respect, be said to have lived from the beginning of the world, and to have been making continual additions to his stock of knowledge in every century.
The imagination of man is naturally sublime, delighted with whatever is remote and extraordinary, and running, without control, into the most distant parts of space and time in order to avoid the objects, which custom has rendered too familiar to it.
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.
Self-denial is a monkish virtue.
History is the discovering of the principles of human nature.
Eloquence, at its highest pitch, leaves little room for reason or reflection, but addresses itself entirely to the desires and affections, captivating the willing hearers, and subduing their understanding.
Anticipation of pleasure is, in itself, a very considerable pleasure.
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.
the senses alone are not implicitly to be depended on. We must correct their evidence by reason, and by considerations, derived from the nature of the medium, the distance of the object, and the disposition of the organ, in order to render them, within their sphere, the proper criteria of truth and falsehood.
But, historians, and even common sense, may inform us, that, however specious these ideas of perfect equality may seem, they are really, at bottom, impracticable; and were they not so, would be extremely pernicious to human society. Render possessions ever so equal, men's different degrees of art, care, and industry will immediately break that equality. Or if you check these virtues, you reduce society to the most extreme indigence; and instead of preventing want and beggary in a few, render it unavoidable to the whole community.
Habit may lead us to belief and expectation but not to the knowledge, and still less to the understanding, of lawful relations.
Nothing indeed can be a stronger presumption of falsehood than the approbation of the multitude.
The sweetest path of life leads through the avenues of learning, and whoever can open up the way for another, ought, so far, to be esteemed a benefactor to mankind.
That the sun will not rise tomorrow is no less intelligible a proposition, and implies no more contradiction, than the affirmation, that it will rise.
Almost every one has a predominant inclination, to which his other desires and affections submit, and which governs him, though perhaps with some intervals, though the whole course of his life.
Justice is a moral virtue, merely because it has that tendency to the good of mankind, and indeed is nothing but an artificial invention to that purpose. The same may be said of allegiance, of the laws of nations, of modesty, and of good manners. All these are mere human contrivances for the interest of society.
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 anything but the perception.
When I shall be dead, the principles of which I am composed will still perform their part in the universe, and will be equally useful in the grand fabric, as when they composed this individual creature. The difference to the whole will be no greater betwixt my being in a chamber and in the open air. The one change is of more importance to me than the other; but not more so to the universe.

A little philosophy makes a man an Atheist: a great deal converts him to religion
Examine the religious principles which have, in fact, prevailed in the world. You will scarcely be persuaded that they are other than sick men's dreams.

Mohammed praises [instances of] tretchery, inhumanity, cruelty, revenge, and bigotry that are utterly incompatible with civilized society.
The greater part of mankind may be divided into two classes; that of shallow thinkers who fall short of the truth; and that of abstruse thinkers who go beyond it.
The fact that different cultures have different practices no more refutes [moral] objectivism than the fact that water flows in different directions in different places refutes the law of gravity

When I hear that a man is religious, I conclude he is a rascal!
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.
A man who has cured himself of all ridiculous prepossessions, and is fully, sincerely, and steadily convinced, from experience as well as philosophy, that the difference of fortune makes less difference in happiness than is vulgarly imagined; such a one does not measure out degrees of esteem according to the rent-rolls of his acquaintance. ... his internal sentiments are more regulated by the personal characters of men, than by the accidental and capricious favors of fortune.
To hate, to love, to think, to feel, to see; all this is nothing but to perceive.
The life of man is of no greater importance to the universe than that of an oyster.
The difference between a man who is led by opinion or emotion and one who is led by reason. The former, whether he will or not, performs things of which he is entirely ignorant; the latter is subordinate to no one, and only does those things which he knows to be of primary importance in his life, and which on that account he desires the most; and therefore I call the former a slave, but the latter free.
Truth springs from argument amongst friends.
I do not have enough faith to believe there is no god.
