The extraordinary phenomenon of what religious people call "conversion," a phenomenon which implies a change of heart so unexpected and startling as to seem miraculous, is a proof of how unwise it is to be in any particular case rigidly dogmatic as to where the sunken rock of destiny really begins. So many appearances have taken the shape of this finality, so many mirages of "false fate" have paralysed our will, that it is wisest to believe to the very end of our days that our attitude to destiny can change and modify destiny. Assuming then that the articulation of the mystery of life which has been outlined in this book, under the name of "the philosophy of the complex vision," must remain the barest of intellectual hypotheses until it has manifested itself in "conduct"; and assuming further that this "conduct" includes the whole of that portion of life, whether contemplative or active, which can be reduced to a fine art by the effort of the will; the question emerges--what kind of effort must the will make, both interiorally and exteriorally, if it desire to respond, by a rhythmic reciprocity, to the vision which the intellect has accepted? It must be remembered that the vision upon which this philosophy depends and from which it derives its primordial assumptions is not the normal vision of the human soul. The philosophy of the complex vision rejects the normal vision of the human soul on behalf of the abnormal vision of the human soul. Its point of view, in this matter, is that the human soul only arrives at the secret of the universe in those exalted, heightened, exceptional and rare moments, when all the multiform activities of the soul's life achieve a musical consummation. Its point of view is that since philosophy, at its deepest and highest, necessarily becomes art; and since art is a rare and difficult thing requiring infinite adjustments and reconciliations; what philosophy has really to use, in formulating any sort of adequate system, is the memory of such rare moments after they have passed away. The point of view from which we have made all our basic assumptions is the point of view that the secret of the universe is only revealed to man in rare moments of ecstasy; and that what man's reason has to do is to gather together in memory the broken and scattered fragments of these moments and out of this residuum build up and round off, as best it may, some coherent interpretation of life. From all this it follows that the first rhythmic reply of the human will to the vision to serve is a passionate act of what might be called "contemplative tension," in the direction of the reviving of such memories, and in the direction of preparing the ground for the return of another "moment of vision" similar in nature to those that have gone before.
