You ask me if the movements of animals are spontaneous; my answer is, "I cannot tell," but analogy points… — Jean Jacques Rousseau
You ask me if the movements of animals are spontaneous; my answer is, "I cannot tell," but analogy points that way. You ask me again, how do I know that there are spontaneous movements? I tell you, "I know it because I feel them." I want to move my arm and I move it without any other immediate cause of the movement but my own will. In vain would any one try to argue me out of this feeling, it is stronger than any proofs; you might as well try to convince me that I do not exist.
It is no more possible for me to conceive how my will moves my body than to conceive how my sensations affect my mind. I do not even know why one of these mysteries has seemed less inexplicable than the other.

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.
