ence; and we may confidently believe with one of the greatest poets of the century—

That life is not as idle ore,

But iron dug from central gloom,

And heated hot with burning fears,
And dipt in baths of hissing tears,
And batter'd with the shocks of doom
To shape and use.

We thus find that the Darwinian theory, even when carried out to its extreme logical conclusion, not only does not oppose, but lends a decided support to, a belief in the spiritual nature of man. It shows us how man's body may have been developed from that of a lower animal form under the law of natural selection; but it also teaches us that we possess intellectual and moral faculties which could not have been so developed, but must have had another origin; and for this origin we can only find an adequate cause in the unseen universe of Spirit.

APPENDIX

I AM glad to be able to quote the opinion of the late Professor Huxley in support of one of the more important arguments adduced in this chapter as to certain human faculties being such as could not have been developed by the agency of natural selection. Mr. Wilfred Ward (in the Nineteenth Century of August 1896) states, that Huxley once said to him: "One thing which weighs with me against pessimism, and tells for a benevolent Author of the Universe, is, my enjoyment of scenery and music. I do not see how they can have helped in the struggle for existence. They are gratuitous gifts."
