Can we still forgive if we can't forget?

I'm not sure I understand the theme of this draft. Let's leave Snowden out of it, because he may have meant something different, and what's important is what you mean. It seems evident to me that the quantity of memory is not related to the quantity of information. I remember my childhood quite vividly and in much detail, even though there are no Facebook pages and (by contemporary standards) few photographs. So even if there is an inverse relationship between memory and forgiveness I don't think your problem of forgiveness is made harder by the 21st century.

Nor do I understand why a feeling of jealousy seeing an old girlfriend with someone else should be considered an aspect of the problem of forgiveness: what have you to forgive? Your feeling of jealousy is the problem, so because you are not wronged you are not called upon to forgive. Perhaps you mean that every former girlfriend you have has wronged you. That too is a sign, however, that does not unambiguously point to forgiveness you should undertake.

But these confusions that I have seem to me peripheral, in a way. The point that seems most uncertain to me is the apparent premise that to remember is to be less able to forgive. But this would seem to imply that perfect amnesia would forgive all. Tout ne pas comprendre, c'est tout pardonner, which is ironic, but not very convincing. Forgiveness is a positive, active process: loving mercy for its own sake, not an absence of consciousness of wrongs suffered. How can we forgive what we do not remember?

So the best way forward here, from my point of view, would be to make the underlying psychological propositions a little clearer. That would allow the next draft to state its theme directly, without the need for Edward Snowden intermediating. You could start fro forgiveness and work outward.
