It is from this absolute indifference and tranquillity of the mind, that mathematical speculations derive some of the most considerable advantages; because there is nothing to interest the imagination; because the judgment sits free and unbiased to examine the point. All proportions, every arrangement of quantity, is alike to the understanding, because the same truths result to it from all; from greater from lesser, from equality and inequality.

Whatever is fitted in any sort to excite the ideas of pain and danger, that is to say, whatever is in any sort terrible, or is conversant about terrible objects, or operates in a manner analogous to terror, is a source of the sublime; that is, it is productive of the strongest emotion which the mind is capable of feeling... When danger or pain press too nearly, they are incapable of giving any delight, and are simply terrible; but at certain distances, and with certain modifications, they may be, and they are, delightful, as we every day experience.

Education is the cheap defense of nations.

Despots govern by terror. They know that he who fears God fears nothing else; and therefore they eradicate from the mind, through their Voltaire, their Helvetius, and the rest of that infamous gang, that only sort of fear which generates true courage.

An event has happened, upon which it is difficult to speak, and impossible to be silent.

General rebellions and revolts of a whole people never were encouraged now or at any time. They are always provoked.

Nothing is so fatal to religion as indifference.
