All our wisdom consists in servile prejudices. All our practices are only subjection, impediment, and constraint. Civil man is born, lives, and dies … - Jean-Jacques Rousseau

The person who has lived the most is not the one with the most years but the one with the richest experiences.

If one divided all of human science into two parts - the one common to all men, the other particular to the learned - the latter would be quite small in comparison with the former. But we are hardly aware of what is generally attained, because it is attained without thought and even before the age of reason; because, moreover, learning is noticed only by its differences, and as in algebraic equations, common quantities count for nothing.

It is a bad mark against a society that those who lead it need so much Science; if men were what they ought to be, they would scarcely need to study in order to learn the things they have to do.
