"The man," he answered, "who sings loudly, clearly, and well, is a man in good health. He is master of himself. He is strict and well-managed. When people hear him they say, 'Here is a prompt, ready, and serviceable man. He is not afraid. There is no rudeness in him. He is urbane, swift, and to the point. There is method in this fellow.' All these things may be in the man who does not sing, but singing makes them apparent. Therefore in our trade we sing."
His conversation so pleases Belloc that lacking a copper pot to tin he instead offers this observation:
Then I said, "You are right, and I wish to God I had something to tin; let me however tell you something in place of the trade I cannot offer you. All things are trine, as you have heard" (here he nodded), "and your singing does, therefore, not a double but a triple good. For it gives you pleasure within, it brings in trade and content from others, and it delights the world around you. It is an admirable thing."
Friedrich von Hügel is another who goes by the Law of Trine: (extracts taken fromThe Mystical Element of Religion which is in Readings from Friedrich von Hügel by Algar Thorold available on Internet Archive)
About the first stage of the religious life, the child's religion, he makes an observation which history has belied:
And at this stage the External, Authoritative, Historical, Traditional, Institutional side and function of Religion are everywhere evident. Cases like that of John Stuart Mill, of being left outside of all religious tradition, we may safely say, will ever remain exceptions to help prove the rule.
One recalls the case of Andre and Simone Weil who were ignorant of the fact that they were Jewish until they both found out at the same time at the age of 13 and 10 respectively.
At that first stage there is a comfortable concreteness to the fact of religion but with adolescence:
But soon there wakes up another activity and requirement of human nature, and another side of religion comes forth to meet it. Direct experience, for one thing, brings home to the child that these sense-informations are not always trustworthy, or identical in its own case and in that of others. And, again, the very impressiveness of this external religion stimulates indeed the sense of awe and of wonder, but it awakens curiosity as well. The time of trustful questioning, but still of questioning, first others, then oneself, has come. The old impressions get now more and more consciously sought out, and selected from among other conflicting ones; the facts seem to clamour for reasons to back them, against the other hostile facts and appearances, or at least against those men in books, if not in life, who dare to question or reject them. Affirmation is beginning to be consciously exclusive of its contrary: I begin to feel that I hold this, and that others hold that; and that I cannot do both; and that I do the former, and exclude and refuse the latter.
Here it is the reasoning, argumentative, abstractive side of human nature that begins to come into play. Facts have now in my mind to be related, to be bound to other facts, and men to men; the facts themselves begin to stand for ideas or to have the latter in them or behind them. The measuring-rod seems to be over all things. And religion answers this demand by clear and systematic arguments and concatenations: this and this is now connected with that and that; this is true or this need not be false, because of that and that. Religion here becomes Thought, System, a Philosophy.
Clearly it is at this point that the rationalistic attitudes of mentors and teachers can have an effect and it is a commonplace if inaccurate theory that here there is an awakening into maturity expressed by the jettisoning of the cargo cult of childhood. Is it really like that or is it an atrophying of the religious life through disuse? There are philosophers who fancy that the Argument from Evil or lacunae in The Five Ways could play a part.
In any event in the natural progression there is a third opening to the religious life:
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 analysed, is action and power, rather than either external fact or intellectual verification.
All religion, Friedrich von Hügel holds, will have aspects of this tripartite schema. He finds it in both the individual and the collective whether that be religious movements that seem absorbed in one stage more than another. Even orders of the Catholic Church seem to reflect this natural division. There is danger and difficulty in transition:
The transition from the child's religion, so simply naive and unselfconscious, so tied to time and place and particular persons and things, so predominantly traditional and historical, institutional and external, to the right and normal type of a young man's religion, is as necessary as it is perilous. The transition is necessary. For all the rest of him is growing, —body and soul are growing in clamorous complexity in every direction: how then can the deepest part of his nature, his religion, not require to grow and develop also? And how can it permeate and purify all the rest, how can it remain and increasingly become "the secret source of all his seeing," of his productiveness and courage and unification, unless it continually equals and exceeds all other interests within the living man, by its own persistent vitality, its rich and infinite variety, its subtle, ever-fresh attraction and inexhaustible resourcefulness and power? But the crisis is perilous. For he will be greatly tempted either to cling exclusively to his existing, all but simply institutional, external position, and to fight or elude all approaches to its reasoned, intellectual apprehension and systematisation; and in this case his religion will tend to contract and shrivel up, and to become a something simply alongside of other things in his life. Or he will feel strongly pressed to let the individually intellectual simply supplant the institutional, in which case his religion will grow hard and shallow, and will tend to disappear altogether. In the former case he will, at best, assimilate his religion to external law and order, to Economics and Politics; in the latter case he will, at best, assimilate it to Science and Philosophy. In the first case, he will tend to superstition; in the second, to rationalism and indifference.
But even if he passes well through this first crisis, and has thus achieved the collaboration of these two religious forces, the external and the intellectual, his religion will still be incomplete and semi-operative, because still not reaching to what is deepest and nearest to his will. A final transition, the addition of the third force, that of the emotional-experimental life, must yet be safely achieved. And this again is perilous: for the two other forces will, even if single, still more if combined, tend. to resist this third force's full share of influence to the uttermost. To the external force this emotional power will tend to appear as akin to revolution; to the intellectual side it will readily seem mere subjectivity and sentimentality ever verging on delusion. And the emotional-experimental force will, in its turn, be tempted to sweep aside both the external, as so much oppressive ballast; and the intellectual, as so much hair-splitting or rationalism. And if it succeeds, a shifting subjectivity, and all but incurable tyranny of mood and fancy, will result,—fanaticism is in full sight.
Friedrich von Hügel 's schema has the sense of a truth so true that it is easy to overlook. It may be and this is a speculation of mine own, that those who lose their faith and come back into it again have to revisit those three stages and relive them in a different light and also undergo the dangers of transition.
