Out of this whirling, seething, bubbling universe of warring and clashing forces man has emerged. How impossible it all seems to reason! Experience alone tells us that it is true. Upon the past history of the earth and of the race of man we may predict astonishing changes and transformations for the future of both, because the continuity of cause and effect is not broken; but the perpetuity of the “me” and the “you” is not implied. All that is implied is the perpetuity of the sum of physical forces. But as to the future of the individual, standing upon the past or upon the present, what are we safe in affirming? Only this--that as we had a beginning we shall have an ending; that as yesterday we were not, so to-morrow we shall not be. A man is like the electric spark that glows and crackles for an instant between two dark, silent, inscrutable eternities. The fluid is not lost, but that tiny bolt has come and gone. Darkness and silence before; darkness and silence after. I do not say this is the summing up of the whole question of immortality. I only mean to say that this is where the argument from analogy lands us. We can argue from the known to the unknown in a restricted way. We do this in life and in science continually. We do not know that the fixed stars have worlds revolving about them; yet the presumption, based upon our own solar system, is that they have. But could we infer other suns, from the existence of our own, were no others visible? Could we predict the future of the earth did we not know its past, or read aright its past did we not know its present state? From an arc we can complete a circle. We can read the big in the little. The motion of a top throws light upon the motion of the earth. An ingenious mind finds types everywhere, but real analogies are not so common.
