We see, then, in the founding and development of the sexual impulse the first movement of the _élan vital_ along its true path of evolution. The _élan vital_ determines progress; it is the unrest, the divine discontent of spirit creating itself in matter[32]. It progresses along various roads, but the road that leads it to its own fulfilment lies through sex. The _élan vital_ becomes _libido_ in an even narrower sense than that, almost co-extensive with Bergson’s term, which Jung gives to the word. For through sex the sense of individual, and subsequently personal, inter-relationship comes into being[33]. With the arousing of self-consciousness we find the dawn of love. This is the beginning of understanding. In the intuition of love is born the knowledge of Reality. Faint, partial, obscured by the sex-basis on which it is built up, it is yet the key to the mystery of being. Gradually, slowly, amid disappointing foulness and blind passion, it still grows. In its insistence on relationship it is manifested as the human aspect of religion. Side by side with it grows the knowledge and love of God. This is the divine aspect of religion, and the two together make the world and the activity of the spirit an intelligible whole. The “What is Truth” of jesting Pilate finds here its answer. All truth, all life, all process, in short Reality itself, is known in the knowledge of the creative love which is the activity of spirit. We see sex growing to greater and greater importance until we reach man. Then self-consciousness intervenes; the ideas of relation and of fellowship dawn; love finds a beginning, and then sex begins to lose its privileged place. From pre-eminence it sinks to a secondary position. Its spiritual part is nearly played, and something higher carries on the work. Love is more than passion. Sex must continue to function, for man has still a physical body; but its spiritual significance is understood, and that is a thing far greater than itself. As love grows, passion sinks and sinks from its first prominence, till love is all. “They neither marry nor are given in marriage, but are as the angels.” If this means anything at all, it means that in the end the physical body will have played its noble part and pass away, with its passions and its failures; while the life goes on, revealed in a body spiritual.
