Such a monism was once taught in the Far East. The Indian doctrine of the fundamental identity of the individual and the universal life, and, more especially, of the ideal identity of the individual with the Universal Soul, makes an end, once and
for all, of the false dualism of the human and the Divine, and provides for the return of the Lord and Giver of Life from his exile in the supernatural dreamland to his home at the heart of Nature. If Western thought will accept this doctrine as a provisional theory of things, and try to master its meaning, it will be able to extend the conception of natural law to the inner life of man and to all the worlds--moral, aesthetic, poetic, religious, and the rest--which the ferment of that life has generated; it will be able, in due course, to take in hand the task for which its special bent and special training are even now equipping it, the task of building up the science of the soul.
When it takes that task in hand, it will find that Buddha has anticipated it, to the extent of indicating the main lines on which it will have to work. An attempt has been made by some of the Western exponents of Buddhism to show that the teaching of Buddha falls into line with the anti-idealistic theories of the dominant school of Western thought. The attempt has not been successful; for it can be shown, I think, that Buddha based his scheme of life, not on rejection of the "soul-theory," but on whole-hearted acceptance of it. But those who contend that Buddha's is modern and Western, have come within a little of stumbling
upon an important truth. Though he belonged to a far-off age and a far-off land, the founder of Buddhism was akin to us in the scientific bent of his mind, in his grasp of the idea of law. His teaching does not fall into line with our thought, for in truth he was far more "advanced" than we are; but it is possible that our thought, as it develops, will come into line with his teaching.
The scientific achievements of the West, so far as they have any philosophical significance, fall under two main heads, the discovery (if I may use the word), on the physical plane, that the Kingdom of Nature is under the reign of law (a conception of Nature which Science must have unconsciously brought with her to her work of investigation, and which has made that work possible); and the further discovery that all laws of Nature are subordinate to the master law of development or growth. Both these discoveries were anticipated by Buddha; but they were made by him--or by the thinkers who sowed what he reaped--not on the physical plane, but on the spiritual, on the plane of man's inner life. Buddha realized, as no man before (or since) had ever done, that the soul is a living thing, and that, as such, it comes under the all-pervading, all-controlling law of growth. And he realized the practical bearing of this conception.
