Soul and body, I suggest react sympathetically upon each other. A change in the state of the soul produces a change in the shape of the body and conversely, a change in the shape of the body produces a change in the state of the soul.
AristotleFor man, when perfected, is the best of animals, but, when separated from law and justice, he is the worst of all; since armed injustice is the more dangerous, and he is equipped at birth with the arms of intelligence and with moral qualities which he may use for the worst ends. Wherefore, if he have not virtue, he is the most unholy and the most savage of animals, and the most full of lust and gluttony. But justice is the bond of men in states, and the administration of justice, which is the determination of what is just, is the principle of order in political society.
AristotleBut a man's best friend is the one who not only wishes him well but wishes it for his own sake (even though nobody will ever know it): and this condition is best fulfilled by his attitude towards himself - and similarly with all the other attributes that go to define a friend. For we have said before that all friendly feelings for others are extensions of a man's feelings for himself.
