# Quote — Jean Jacques Rousseau, Emile; or On Education

> As the sentient being becomes active his discernment develops along with his strength. Not till his strength is in excess of what is needed for self-preservation, is the speculative faculty developed, the faculty adapted for using this superfluous strength for other purposes. Would you cultivate your pupil's intelligence, cultivate the strength it is meant to control. Give his body constant exercise, make it strong and healthy, in order to make him good and wise; let him work, let him do things, let him run and shout, let him be always on the go; make a man of him in strength, and he will soon be a man in reason.

> Speaking generally, there is nothing duller than a peasant or sharper than a savage. What is the cause of this difference? The peasant has always done as he was told, what his father did before him, what he himself has always done; he is the creature of habit, he spends his life almost like an automaton on the same tasks; habit and obedience have taken the place of reason. The case of the savage is very different; he is tied to no one place, he has no prescribed task, no superior to obey, he knows no law but his own will; he is therefore forced to reason at every step he takes. He can neither move nor walk without considering the consequences. Thus the more his body is exercised, the more alert is his mind; his strength and his reason increase together, and each helps to develop the other.
