The Nature of Eternity
Hence we must say: In the idea of the ego there is no reality, but the idea enables us to assume the reality of our ego. But how do we gain certain knowledge of the ego in ordinary life? We can acquire this knowledge by living not only in the present but also, through memory, in the past. If, on looking back to preceding days, weeks, years, even decades, to the point of time in our childhood where memory can take us, we could never link in one chain, as it were, all the experiences of our own inner life; it would indeed be impossible to speak at all of ego. What certain psychologists have said is quite correct: a man loses his ego, or at least consciousness of it, to the extent that the recollection of his experiences up to the time in question is wiped out. In so far as our memory fails, our ego breaks up.
