Of course he has not arrived at his conclusion by a system of rigid proof; it has already been pointed out how impossible it is to arrive at the greater truths of life in such a manner.
He has done, however, that which can be reasonably expected in such cases.

To begin with, he has given us a striking analysis of the essential characteristics of human life, and he has found there a yearning and a void.

He has given us a masterly discussion of eternal truth as contrasted with the temporary expressions of it.

He has taught us how the present can overcome the past, and how man can ascend beyond the subjective and material.

And he has led us to feel that reality must lie in the eternal that appears to be at the basis of the highest and greatest in man.
Moreover, he has given a fair and thorough treatment of the solutions that have been offered in the past.
