People always play carelessly in games where there is no danger. A falling kite hurts nobody, but nothing… — Jean Jacques Rousseau
People always play carelessly in games where there is no danger. A falling kite hurts nobody, but nothing makes the arm so supple as protecting the head, nothing makes the sight so accurate as having to guard the eye. To dash from one end of the room to another, to judge the rebound of a ball before it touches the ground, to return it with strength and accuracy, such games are not so much sports fit for a man, as sports fit to make a man of him.

Where is the man who owes nothing to the land in which he lives? Whatever that land may be, he owes to it the most precious thing possessed by man, the morality of his actions and the love of virtue.
Gluttony is the vice of feeble minds. The gourmand has his brains in his palate, he can do nothing but eat; he is so stupid and incapable that the table is the only place for him, and dishes are the only things he knows anything about. Let us leave him to this business without regret; it is better for him and for us.
Nature never deceives us; it is always we who deceive ourselves.
