It is our endeavor to show that the providence of God which governs the universe with justice also rules immortal souls on the most equitable princip… - Origen

And therefore, so far as we are concerned, the followers of Pythagoras, who abstain from all things that contain life may do as they please; only observe the different reason for abstaining from things that have life on the part of the Pythagoreans and our ascetics. For the former abstain on account of the fable about the transmigration of souls, as the poet says:—“And some one, lifting up his beloved son,Will slay him after prayer; O how foolish he!”We, however, when we do abstain, do so because “we keep under our body, and bring it into subjection,” (Cf. I Co. ix. 27) and desire “to mortify our members that are upon the earth, fornication, uncleanness, inordinate affection, evil concupiscence;” (Cf. Col. iii. 5) and we use every effort to “mortify the deeds of the flesh.” (Cf. Rom viii. 13)

It is manifest, further, that the language used regarding the wrath of God is to be understood figuratively from what is related of His “sleep,” from which, as if awaking Him, the prophet says: “Awake, why sleepest Thou, Lord?” and again: “Then the Lord awaked as one out of sleep, and like a mighty man that shouteth by reason of wine.”

Suppose a man has gradually become skilled in the science or art, let us say, of geometry or medicine, up to the point of reaching perfection, having trained himself for a long time by instructions and exercises so as to acquire completely the knowledge of the aforesaid art. It could surely never happen that such a man should lie down to sleep with all this skill and wake up without it. It is not to the point to bring forward or take account here of accidents which happen through some injury or weakness, for these do not apply in the case we have proposed as an illustration. According to that, so long as the geometrician or doctor in question occupies himself in the studies and rational instructions relating to his art, a knowledge of the subject will remain with him. If, however, he loses interest in these exercises and neglects to work, then thtough this negligence ~is knowledge is gradually lost, a few derails at first, then more, and so on until after a long time the whole vanishes into oblivion and is utterly erased from his memory.
