What do we mean by thought? When do you think? Obviously, thought is the result of a response, neurological or psychological, the response of stored-up memory. There is the immediate response of the nerves to a sensation, and there is the psychological response of stored-up memory, the influence of race, group, guru, family, tradition, and so on – all of which you call thought. So, the thought process is the response of memory, is it not? You would have no thoughts if you had no memory, and the response of memory to a certain experience brings the thought process into action. – Krishnamurti, What Are You Doing with Your Life?
