Thinking requires space in which to forget, to select, to delate

Memory by itself can only accumulate data, pointlessly and meaninglessly. Remember Jorge Luis Borges’s philosophical parable “Funes the Memorious.” Funes is a young man who, falling on his head from a horse, becomes strangely crippled: his memory hyper-develops, he is deprived of any ability to forget, he remembers everything; his mind becomes a monstrous garbage dump cluttered and clogged with irrelevant data, a gigantic heap of unrelated images and disconnected instants; he cannot evacuate any fragment of past experiences, however trifling. This relentless capacity for absolute and continuous recollection is a curse; it excludes all possibility of thought. For thinking requires space in which to forget, to select, to delete and to isolate what is significant. If you cannot discard any item from the memory store, you cannot abstract and generalise. But without abstraction and generalisation, there can be no thought.
