“Among the many short cuts to science, we badly need someone to teach us the art of learning with difficulty.”

“For if men needed speech in order to learn to think, they had a still greater need for knowing how to think in order to discover the art of speaking" - Rousseau”

“I hate books; they only teach us to talk about things we know nothing about.”

“A feeble body makes a feeble mind. I do not know what doctors cure us of, but I know this: they infect us with very deadly diseases, cowardice, timidity, credulity, the fear of death. What matter if they make the dead walk, we have no need of corpses; they fail to give us men, and it is men we need.”

“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.”

“We are born weak, we need strength; helpless, we need aid; foolish,we need reason. All that we lack at birth, all that we need whenwe come to man's estate, is the gift of education.”

“The extreme inequality of our ways of life, the excess of idleness among some and the excess of toil among others, the ease of stimulating and gratifying our appetites and our senses, the over-elaborate foods of the rich, which inflame and overwhelm them with indigestion, the bad food of the poor, which they often go withotu altogether, so hat they over-eat greedily when they have the opportunity; those late nights, excesses of all kinds, immoderate transports of every passion, fatigue, exhaustion of mind, the innumerable sorrows and anxieties that people in all classes suffer, and by which the human soul is constantly tormented: these are the fatal proofs that most of our ills are of our own making, and that we might have avoided nearly all of them if only we had adhered to the simple, unchanging and solitary way of life that nature ordained for us. ”
