Søren Kierkegaard Quote
Man is a synthesis of psyche and body, but he is also a synthesis of the temporal and the eternal. In the former, the two factors are psyche and body, and spirit is the third, yet in such a way that one can speak of a synthesis only when the spirit is posited. The latter synthesis has only two factors, the temporal and the eternal. Where is the third factor? And if there is no third factor, there really is no synthesis, for a synthesis that is a contradiction cannot be completed as a synthesis without a third factor, because the fact that the synthesis is a contradiction asserts that it is not. What, then, is the temporal?
