I have resolved to demonstrate by a certain and undoubted course of argument, or to deduce from the very condition of human nature, not what is new and unheard of, but only such things as agree best with practice.

No one doubts but that we imagine time from the very fact that we imagine other bodies to be moved slower or faster or equally fast. We are accustomed to determine duration by the aid of some measure of motion.

The more a government strives to curtail freedom of speech, the more obstinately is it resisted; not indeed by the avaricious, ... but by those whom good education, sound morality, and virtue have rendered more free.

Nature is satisfied with little; and if she is, I am also.

He whose honor depends on the opinion of the mob must day by day strive with the greatest anxiety, act and scheme in order to retain his reputation. For the mob is varied and inconsistent, and therefore if a reputation is not carefully preserved it dies quickly.

I do not believe anyone has reached such perfection, surpassing all others, except Christ, to whom God immediately revealed - without words or visions - the conditions which lead to salvation.

All the objects pursued by the multitude not only bring no remedy that tends to preserve our being, but even act as hinderances, causing the death not seldom of those who possess them, and always of those who are possessed by them.
