One can generally say this about men: that they are ungrateful, fickle, simulators and deceivers, avoiders of danger, greedy for gain; and while you work for their good they are completely yours, offering you their blood, their property, their lives, and their sons when danger is far away; but when it comes nearer to you, they turn away.
Socrates.- If all goes well, the time will come when one will take up the memorabilia of Socrates rather than the Bible as a guide to morals and reason... The pathways of the most various philosophical modes of life lead back to him... Socrates excels the founder of Christianity in being able to be serious cheerfully and in possessing that wisdom full of roguishness that constitutes the finest state of the human soul.

People must have renounced, it seems to me, all natural intelligence to dare to advance that animals are but animated machines.... It appears to me, besides, that such people can never have observed with attention the character of animals, not to have distinguished among them the different voices of need, of suffering, of joy, of pain, of love, of anger, and of all their affections. It would be very strange that they should express so well what they could not feel.
