On the Giants (28-29)

On which account, it is possible that the spirit of God may remain in the soul, but that it should remain for ever is impossible, as we have said. And why need we wonder? since there is no other thing whatever, the possession of which, is stable and lasting; but mortal affairs are continually wavering in the scale, and inclining first to one side, and then to the other, and liable at different times to different changes.

And the greatest cause of our ignorance is the flesh, and our inseparable connection with the flesh. And this, Moses represents God as admitting, where he says that, "Because they are flesh," the spirit of God cannot abide in them. And yet marriage and the rearing of children, and the furnishing of necessary things, and ingloriousness conjoined with a want of money and business, both private and public, and a countless number of other things cause wisdom to waste away, before it begins to flourish vigorously.
