the Roman Catholic Index of Prohibited Books, a list that came to include almost every significant work of post-medieval Western philosophy. - David Hume

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.

A wise man apportions his beliefs to the evidence.

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.
