Philo of Alexandria · 1645 of 1726
Appendix 2 · The words of Philo.
Sleep, according to the prophet, is a trance, not indeed in accordance with insanity, but proceeding from a relaxation of the outward senses and the retreat of reason; for at that time the outward senses cease from attaching themselves to their proper objects, and the mind is quiet, neither being any longer under the influence nor affording any motion to them, and they, being in consequence cut off from any energy because they are separated from the objects which are perceptible to them, are dissolved in a state of motionless inactivity.
