But the idols of the Market Place are the most troublesome of all: idols which have crept into the understanding through their alliances with words and names. For men believe that their reason governs words. But words turn and twist the understanding. This it is that has rendered philosophy and the sciences inactive. Words are mostly cut to the common fashion and draw the distinctions which are most obvious to the common understanding. Whenever an understanding of greater acuteness or more diligent observation would alter those lines to suit the true distinctions of nature, words complain.

Philosophy when superficially studied, excites doubt, when thoroughly explored, it dispels it.

By far the best proof is experience.

A man that hath no virtue in himself, ever envieth virtue in others. For men's minds, will either feed upon their own good, or upon others' evil; and who wanteth the one, will prey upon the other; and whoso is out of hope, to attain to another's virtue, will seek to come at even hand, by depressing another's fortune.

It is as hard and severe a thing to be a true politician as to be truly moral.
