Chapter III

Behind the riddle of space stood at that period of my life the riddle of time. Might a conception be possible here also which would contain within itself in idea a return out of the past by way of an advance into the infinitely distant future? My happiness over the space conception caused a profound unrest over that of time. But there was then visible no way out. All efforts of thought led only to the realization that I must beware especially of applying the clear conception of space to the problem of time. All clarification which the striving for understanding could bring was frustrated by the riddle of time. The stimulus which I had received from Zimmermann toward the study of aesthetics led me to read the writings of the famous specialist in aesthetics of that time, Friedrich Theodor Vischer. I found in a passage of his work a reference to the fact that more recent scientific thought rendered necessary a change in the conception of time. There was always a sense of joy aroused in me when I found in others the recognition of any cognitional need which I had conceived. In this case it was like a confirmation in my struggle toward a satisfying concept of time.
