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.

In all things, therefore, where we have clear evidence from our ideas, and those principles of knowledge I have above mentioned, reason is the proper judge; and revelation, though it may, in consenting with it, confirm its dictates, yet cannot in such cases invalidate its decrees: nor can we be obliged, where we have the clear and evident sentience of reason, to quit it for the contrary opinion, under a pretence that it is matter of faith: which can have no authority against the plain and clear dictates of reason.

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.

Children should from the beginning be bred up in an abhorrence of killing or tormenting any living creature; and be taught not to spoil or destroy any thing, unless it be for the preservation or advantage of some other that is nobler.

All wealth is the product of labor.

The great art to learn much is to undertake a little at a time.

Justice and truth are the common ties of society
