3. Chap. II.
Allow me, therefore, to bring before you a subject which I beseech you not to refuse to open up and discuss with me. Many are perplexed by questions concerning the soul, and I confess that I myself am of this number. I shall in this letter, in the first place, state explicitly the things regarding the soul which I most assuredly believe, and shall, in the next place, bring forward the things regarding which I am still desirous of explanation.
The soul of man is in a sense proper to itself immortal. It is not absolutely immortal, as God is, of whom it is written that He "alone hath immortality," 1 for Holy Scripture makes mention of deaths to which the soul is liable--as in the saying, "Let the dead bury their dead;" 2 but because when alienated from the life of God it so dies as not wholly to cease from living in its own nature, it is found to be from a certain cause mortal, yet so as to be not without reason called at the same time immortal.
The soul is not a part of God. For if it were, it would be absolutely immutable and incorruptible, in which case it could neither go downward to be worse, nor go onward to be better; nor could it either begin to have anything in itself which it had not before, or cease to have anything which it had within the sphere of its own experience. But how different the actual facts of the case are is a point requiring no evidence from without, it is acknowledged by every one who consults his own consciousness. In vain, moreover, is it pleaded by those who affirm that the soul is a part of God, that the corruption and baseness which we see in the worst of men, and the weakness and blemishes which we see in all men, come to it not from the soul itself, but from the body; for what matters it whence the infirmity originates in that which, if it were indeed immutable, could not, from any quarter whatever, be made infirm? For that which is truly immutable and incorruptible is not liable to mutation or corruption by any influence whatever from without, else the invulnerability which the fable ascribed to the flesh of Achilles would be nothing peculiar to him, but the property of every man, so long as no accident befell him. That which is liable to be changed in any manner, by any cause, or in any part whatever, is therefore not by nature immutable; but it were impiety to think of God as otherwise than truly and supremely immutable: therefore the soul is not a part of God.
