Man's sensations and power to act must go together. Man can know nothing that he cannot somehow weave into action. If he fails to do this in one form or another, it is through limitations he has placed on himself. Man cannot suffer for lack of "more worlds to conquer," because his power to conquer worlds is the product of his own 'past life and his own past needs. To weave knowledge into action is the antidote for ennui. To plan, to hope, to do, to accomplish the full measure of our powers, whatever they may be, is to turn away from Nirvana to real life. A useful man, a helpful man, an active man in any sense, even though his, activity be misdirected or harmful, is always a hopeful man. The feeling that "the only reality in life is pain," is the sign not of philosophical acuteness but of bodily under-vitalization. The nervous system is too feeble for the body it has to move. To act is to make the environment your servant. Its pressure is no longer pain but joy. The concessions which life has made to time and space are the source of life's glory and power. The function of the nervous system is to carry from the environment to the brain the impressions of truth, that action may be true and safe. Pain and pleasure are both incidental to sound action. The one drives, the other coaxes us toward the path of wisdom. If pain is in excess of joy in our experience, it is because we have wandered from the path of normal activity. By right-doing, we mean that action which makes for "abundance of life," and abundance of life means fulness of joy. "Though life be sad, yet there's joy in the living it" was the word of the ancient Greeks, "who ever with a frolic welcome took the Thunder and the Sunshine." The life of man is dynamic, not static; not a condition but a movement. "Not enjoyment and not sorrow" is its end or justification. It is a rush of forces, an evolution towards greater activities and higher adjustment, the growth of a stability which shall be ever more unstable. This onward motion is recognized in the pessimistic philosophy of Von Hartmann, as a movement towards ever greater possibilities of pain. With him life is "the supreme blunder of the blind unconscious force" which created man and developed him as the prey of ever-increasing suffering. But the power to enjoy has grown in like degree, and both joy and pain are subordinated to the power to act. The human will, the power to do, is the real end of the stress and struggle of the ages. However limited its individual action, the will finds its place among the gigantic factors in the evolution of life. It is not the present, but the ultimate, which is truth. Not the unstable and temporary fact but the boundless clashing forces which endlessly throw truths to the surface.
