Our questions and answers are in part determined by the historical tradition in which we find ourselves. We apprehend truth from our own source within the historical tradition.
The content of our truth depends upon our appropriating the historical foundation. Our own power of generation lies in the rebirth of what has been handed down to us. If we do not wish to slip back, nothing must be forgotten; but if philosophising is to be genuine our thoughts must arise from our own source. Hence all appropriation of tradition proceeds from the intentness of our own life. The more determinedly I exist, as myself, within the conditions of the time, the more clearly I shall hear the language of the past, the nearer I shall feel the glow of its life.
