“It is indeed a mortifying reflection to those who are actuated by the love of fame, so justly denominated the last infirmity of noble minds, that the wisest legislator and most exalted genius that ever reformed or enlightened the world can never expect such tributes of praise as are lavished on the memory of pretended saints, whose whole conduct was probably to the last degree odious or contemptible, and whose industry was entirely directed to the pursuit of objects pernicious to mankind. It is only a conqueror, a personage no less entitled to our hatred, who can pretend to the attainment of equal renown and glory.”

“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. The most rigorous inquisition too is requisite to watch every inequality on its first appearance; and the most severe jurisdiction, to punish and redress it. But besides, that so much authority must soon degenerate into tyranny, and be exerted with great partialities; who can possibly be possessed of it, in such a situation as is here supposed? Perfect equality of possessions, destroying all subordination, weakens extremely the authority of magistracy, and must reduce all power nearly to a level, as well as property. We may conclude, therefore, that in order to establish laws for the regulation of property, we must be acquainted with the nature and situation of man; must reject appearances, which may be false, though specious; and must search for those rules, which are, on the whole, most useful and beneficial.”

“The admirers and followers of the Al Koran insist on the excellent moral precepts interspersed throughout that wild and absurd performance...Would we know, whether the pretended prophet had really attained a just sentiment of morality, let us attend to his narration, and we shall soon find, that he bestows praise upon such instances of treachery, inhumanity, cruelty, revenge, bigotry, as are utterly incompatible with civilised society. No steady rule of right conduct seems there to be attended to: and every action is blamed or praised, so far only as it is beneficial or harmful to the true believers.”

“He is happy whose circumstances suit his temper, but he is more excellent who can suit his temper to his circumstance.”

“The sweetest and most inoffensive path of life leads through the avenues of science and learning; and whoever can either remove any obstructions in this way, or open up any new prospect, ought so far to be esteemed a benefactor to mankind. And though these researches may appear painful and fatiguing. It is with some minds as with some bodies, which being endowed with vigorous and florid health, require severe exercise, and reap a pleasure from what, to the generality of mankind, may seem burdensome and laborious. Obscurity, indeed, is painful to the mind as well as to the eye; but to bring light from obscurity, by whatever labour, must needs be delightful and rejoicing.”

“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…. If any one, upon serious and unprejudic'd reflection 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.”
