Unfortunately, I am not a philosopher and not a theologian. I know perfectly well that I cannot live more than another six months; it might be supposed that I ought now to be chiefly concerned with the question of the shadowy life beyond the grave, and the visions that will visit my slumbers in the tomb. But for some reason my soul refuses to recognize these questions, though my mind is fully alive to their importance. Just as twenty, thirty years ago, so now, on the threshold of death, I am interested in nothing but science. As I yield up my last breath I shall still believe that science is the most important, the most splendid, the most essential thing in the life of man; that it always has been and will be the highest manifestation of love, and that only by means of it will man conquer himself and nature. This faith is perhaps naive and may rest on false assumptions, but it is not my fault that I believe that and nothing else; I cannot overcome in myself this belief.
