“How grievously I was disappointed! …I found my philosopher altogether forsaking mind and any other principle of order, but having recourse to air, and ether, and water, and other eccentricities. I might compare him to a person that began by maintaining generally that mind is the cause of the actions of Socrates, but who, when endeavored to explain the causes of my several actions in detail, went on to show that I sit here because my body is made up of bones and muscles; and the bones he would say, are hard and have ligaments which divide them, and the muscles are elastic, and they cover the bones, which also have a covering or environment of flesh and skin which contains them; and as the bones are lifted at their joints by the contraction or relaxation of the muscles, I am able to bend my limbs, and this is why I an sitting here in a curved posture… and he would have a similar explanation of my talking to you, which he would attribute to sound, and air, and hearing, and he would assign ten thousand other causes of the same sort, forgetting to mention the true cause, which is that Athenians have thought fit to condemn me, and accordingly I have thought it better and more right to remain here and undergo my sentence; for I am inclined to think that these muscles and bones of mine would have gone off to Megara or Boeotia… if they had been guided only by their idea of what was best, and if I had not chosen as the better and nobler part… to undergo any punishment that the State inflicts.”

Plato, Phaedo
