Augustine, Confessions §aug_conf_10_020: All these things I remember, and how I learnt them I remember.

All these things I remember, and how I learnt them I remember. Many things also most falsely objected against them have I heard, and remember; which though they be false, yet is it not false that I remember them; and I remember also that I have discerned betwixt those truths and these falsehoods objected to them. And I perceive that the present discerning of these things is different from remembering that I oftentimes discerned them, when I often thought upon them. I both remember then to have often understood these things; and what I now discern and understand, I lay up in my memory, that hereafter I may remember that I understand it now. So then I remember also to have remembered; as if hereafter I shall call to remembrance, that I have now been able to remember these things, by the force of memory shall I call it to remembrance.
