3. _Intuition, Feeling, and Volitional requirements and evidences, the Mature Man’s special approaches to Faith._ But yet a final activity of human nature has to come to its fullest, and to meet its response in a third side of Religion. For if in Physiology and Psychology all action whatsoever is found to begin with a sense-impression, to move through the central process of reflection, and to end in the final discharge of will and of action, the same final stage can be found in the religious life. Certain interior experiences, certain deep-seated spiritual pleasures and pains, weaknesses and powers, helps and hindrances, are increasingly known and felt in and through interior and exterior action, and interior suffering, effort, and growth. For man is necessarily a creature of action, even more than of sensation and of reflection; and in this action of part of himself against other parts, of himself with or against other men, with or against this or that external fact or condition, he grows and gradually comes to his real self, and gains certain experiences as to the existence and nature and growth of this his own deeper personality. Man’s emotional and volitional, his ethical and spiritual powers, are now in ever fuller motion, and they are met and fed by the third side of religion, the Experimental and Mystical. Here religion is rather felt than seen or reasoned about, is loved and lived rather than analyzed, is action and power, rather than either external fact or intellectual verification. II. EACH ELEMENT EVER ACCOMPANIED BY SOME AMOUNT OF THE OTHER TWO. DIFFICULTY OF THE TRANSITIONS FROM ONE STAGE TO THE OTHER. Now these three sides of the human character, and corresponding three elements of Religion, are never, any one of them, without a trace or rudiment of the other two; and this joint presence of three such disparate elements ever involves tension, of a fruitful or dangerous kind.[35] 1. _Utility of this joint presence._ In the living human being indeed there never exists a mere apprehension of something external and sensible, without any interior elaboration, any interpretation by the head and heart. We can hardly allow, we can certainly in nowise picture to ourselves, even an infant of a few hours old, as working, and being worked upon, by nothing beyond these sense-perceptions alone. Already some mental, abstractive, emotional-volitional reaction and interpretation is presumably at work; and not many weeks or months pass before this is quite obviously the case. And although, on the other hand, the impressions of the senses, of the imagination and the memory are, normally, more numerous, fresh, and lasting in early than in later years, yet up to the end they continue to take in some new impressions, and keep up their most necessary functions of supplying materials, stimulants, and tests to the other powers of the soul.
