Memory (and what it implies: memory, forgetting, etc.) is a subject that I consider very important and attractive. I leave out the memory of data, which although it is necessary to cultivate, today, thanks to internet and other technological mechanisms, we can attend. I am interested in the other one, that of experience. Freud had already recognized that there is a necessary relationship of mutual support between memory and oblivion, as points. And other scholars, that our memory is anthological (what would be called "selective"). Our current memory capacity is adversely affected by the lack of attention, of concentration, that the accelerated and saturated world we live in provokes.
The memory that most interests me would be the affective or inner memory, the one that Proust knew how to capture in his great work In search of lost time. I always quote Rilke, when the narrator of his peculiar novel The Notebooks of Malte Lauris Bridge in a moment talking about the poetic process, says that to produce good poetry it is necessary to have diverse experiences, but also to have memories. But then he says, "And it's not enough to have memories either. You have to know how to forget them when there are many, and you have to have the patience to wait for them to come back.
I skip the considerations about voluntary amnesia, especially in politics.
Thank you for your good post, @nancybriti.
