“A little consideration will reveal the absurdity of supposing that the present generation (if one can call ‘present’ that which is in the act of disappearing) or the generations of fifty or a hundred years hence can make a more real and valuable contribution to the human consciousness than those which existed fifty, a hundred or five thousand years ago. Our habit of breaking up time into the past, present and future does not entitle us to endow the last with more reality than the first. From the standpoint of the present, the future is no richer in reality than the past, and our efforts should be with reference, not to the future, but to that eternal present of which both future and past are one. The past has no existence except in our memory; the future is not yet, nor is it certain that it will be.” PastTimeFuturePresent Book:The Meaning of History Source: The Meaning of History
