A theory of spiritual evolution is not identical with a scientific theory of form-evolution and physical life-evolution; it must stand on its own inherent justification: it may accept the scientific account of physical evolution as a support or an element, but the support is not indispensable. The scientific theory is concerned only with the outward and visible machinery and process, with the detail of Nature’s execution, with the physical development of things in Matter and the law of development of Life and Mind in Matter; its account of the process may have to be considerably changed or may be dropped altogether in the light of new discovery, but that will not affect the self-evident fact of a spiritual evolution, an evolution of Consciousness, a progression of the soul’s manifestation in material existence. In its outward aspects this is what the theory of evolution comes to,—there is in the scale of terrestrial existence a development of forms, of bodies, a progressively complex and competent organisation of Matter, of Life in Matter, of Consciousness in living Matter; in this scale, the better organised the form, the more it is capable of housing a better organised, a more complex and capable, a more developed or evolved Life and Consciousness. …

If there is an evolution in material Nature and if it is an evolution of being with consciousness and life as its two key-terms and powers, this fullness of being, fullness of consciousness, fullness of life must be the goal of development towards which we are tending and which will manifest at an early or later stage of our destiny. The Self, the Spirit, the Reality that is disclosing itself out of the first inconscience of life and matter, would evolve its complete truth of being and consciousness in that life and matter. It would return to itself through a spiritual completeness of itself in life. Our evolution in the Ignorance with its chequered joy and pain of self-discovery and world-discovery, its half-fulfilments, its constant finding and missing, is only our first state. It must lead inevitably towards an evolution in the Knowledge, a self-finding and self-unfolding of the Spirit, a self-revelation of the Divinity in things in that true power of itself in Nature which is to us still a Supernature.
