Plato Greek: 428/427 or 424/423 – 348/347 BC) was a philosopher and mathematician in Classical Greece, and the founder of the Academy in Athens, the first institution of higher learning in the Western world. He is widely considered the most pivotal figure in the development of philosophy, especially the Western tradition. Unlike nearly all of his philosophical contemporaries, Plato's entire œuvre is believed to have survived intact for over 2,400 years. Along with his teacher, Socrates, and his most famous student, Aristotle, Plato laid the very foundations of Western philosophy and science. Plato, Wikipedia

Said Plato: "You ought not to attempt to cure the body without the soul." [Snell Manuscript - The Book, page 3]
Mark “Stryder” Stilwell
"Plato compares ordinary men to prisoners bound in a cave, of which they can see only the back wall. On this wall fall shadows cast by those who pass the mouth of the cave. The play of shadows is the prisoner’s world; it is reality to them; but whenever one of them succeeds in freeing himself, and sees the entrance, sees the Light and the real beings moving in it, then he realizes that he has lived in a world of illusion, that he has been ‘in a state of darkness,’ and that his eyes have been ‘hoodwinked.’ We must know ourselves in order to know the world. The man, therefore, who becomes proficient in ‘that most interesting of all human studies, the knowledge of himself,’ renounces the popular world; and he gradually attains consciousness in a world described as ‘not to be touched by hand or to be seen by eye,’ but otherwise supremely real. Withdrawal from this world of illusion, however, involves a transition from the ordinary natural state and standard of living towards what is known as the regenerate state, with its correspondingly higher standard."
