If to break loose from the bounds of reason, and to want that restraint of examination and judgment which keeps us from choosing or doing the worst, be liberty, true liberty, madmen and fools are the only freemen: but yet, I think, nobody would choose to be mad for the sake of such liberty, but he that is mad already.

God, when he makes the prophet, does not unmake the man.

Books seem to me to be pestilent things, and infect all that trade in them...with something very perverse and brutal. Printers, binders, sellers, and others that make a trade and gain out of them have universally so odd a turn and corruption of mind that they have a way of dealing peculiar to themselves, and not conformed to the good of society and that general fairness which cements mankind.

Long discourses, and philosophical readings, at best, amaze and confound, but do not instruct children. When I say, therefore, that they must be treated as rational creatures, I mean that you must make them sensible, by the mildness of your carriage, and in the composure even in the correction of them, that what you do is reasonable in you, and useful and necessary for them; and that it is not out of caprichio, passion or fancy, that you command or forbid them any thing.

A criminal who, having renounced reason ... hath, by the unjust violence and slaughter he hath committed upon one, declared war against all mankind, and therefore may be destroyed as a lion or tiger, one of those wild savage beasts with whom men can have no society nor security.

He that in the ordinary affairs of life would admit of nothing but direct plain demonstration would be sure of nothing in this world but of perishing quickly.

When we know our own strength, we shall the better know what to undertake with hopes of success.
