“The human mind does not work that way. It operates by association. With one item in its grasp, it snaps
instantly to the next that is suggested by the association of thoughts, in accordance with some intricate
web of trails carried by the cells of the brain. It has other characteristics, of course; trails that are not
frequently followed are prone to fade, items are not fully permanent, memory is transitory. Yet the speed
of action, the intricacy of trails, the detail of mental pictures, is awe-inspiring beyond all else in nature.”

Vannevar Bush, As We May Think, 1945.
