In any case, however, arguments about pessimism and optimism based upon considerations regarding fixed attainment of good and evil are mainly literary in quality. Man continues to live because he is a living creature not because reason convinces him of the certainty or probability of future satisfactions and achievements. He is instinct with activities that carry him on. Individuals here and there cave in, and most individuals sag, withdraw and seek refuge at this and that point. But man as man still has the dumb pluck of the animal. He has endurance, hope, curiosity, eagerness, love of action. These traits belong to him by structure, not by taking thought. Memory of past and foresight of future convert dumbness to some degree of articulateness. They illumine curiosity and steady courage. Then when the future arrives with its inevitable disappointments as well as fulfilments, and with new sources of trouble, failure loses something of its fatality, and suffering yields fruit of instruction not of bitterness. Humility is more demanded at our moments of triumph than at those of failure. For humility is not a caddish self-depreciation. It is the sense of our slight inability even with our best intelligence and effort to command events; a sense of our dependence upon forces that go their way without our wish and plan. Its purport is not to relax effort but to make us prize every opportunity of present growth. In morals, the infinitive and the imperative develop from the participle, present tense. Perfection means perfecting, fulfilment, fulfilling, and the good is now or never. Idealistic philosophies, those of Plato, Aristotle, Spinoza, like the hypothesis now offered, have found the good in meanings belonging to a conscious life, a life of reason, not in external achievement. Like it, they have exalted the place of intelligence in securing fulfilment of conscious life. These theories have at least not subordinated conscious life to external obedience, not thought of virtue as something different from excellence of life. But they set up a transcendental meaning and reason, remote from present experience and opposed to it; or they insist upon a special form of meaning and consciousness to be attained by peculiar modes of knowledge inaccessible to the common man, involving not continuous reconstruction of ordinary experience, but its wholesale reversal. They have treated regeneration, change of heart, as wholesale and self-enclosed, not as continuous.
