On The Function of Remembering and Forgetting

The answer, it turns out, is that fuzziness is not a severe limitation but a highly advanced feature. As a matter of engineering, the brain does not have any physical limitations in the amount of information it can hold. It is designed specifically to forget most of the details it comes across, so that it may allow us to form general impressions, and from there useful judgments. Forgetting is not a failure at all, but an active metabolic process, a flushing out of data in the pursuit of knowledge and meaning.”
