In [the soul] one part naturally rules, and the other is subject, and the virtue of the ruler we maintain to be different from that of the subject; the one being the virtue of the rational, and the other of the irrational part. Now, it is obvious that the same principle applies generally, and therefore almost all things rule and are ruled according to nature.
AristotleThe soul suffers when the body is diseased or traumatized, while the body suffers when the soul is ailing.
AristotleIf everything when it occupies an equal space is at rest, and if that which is in locomotion is always occupying such a space at any moment, the flying arrow is therefore motionless.
AristotleWe ought not to listen to those who exhort us, because we are human, to think of human things....We ought rather to take on immortality as much as possible, and do all that we can to live in accordance with the highest element within us; for even if its bulk is small, in its power and value it far exceeds everything.
Aristotle
