§ 26
However, that there is a flaw in my Philosophy and a flaw in my Creed, I do not conceal from myself.—If, underlying and upholding all phenomenal multiplicity, there is a noumenal unity, how it comes about that there is evil and suffering and injustice and pain I do not know. Nor do I know how, if that Unity (including man) is governed by infrangible law, it comes about that we obtain notions of Responsibility and Will; how we feel that we ought to act thus and not otherwise, and have the power to choose the good from the evil.
Yet I comfort myself thus:—Human reason, after all, is inadequate for the explanation of anything superhuman. But there may be in man a faculty of imagination or feeling or emotion or faith—call it what you like—that insists upon our trying to act thus and not otherwise; upon our helping on the good and eradicating the bad; and that leaves the problem of the Origin of Evil and the problem of the Freedom of the Will to another sphere and another stage in the upward emergence of mind.
