That monistic tendency of human thought, which is itself a necessary projection of the monistic reality of the individual soul, cannot, except by an arbitrary act of faith, resolve this ultimate duality into unity. Such a primordial "act of faith" it can and must make with regard to the objective reality of other souls. But such an "act of faith" is not demanded with regard to the unutterable mystery behind the universe. We have not, strictly speaking, even the right to use the expression "an unutterable mystery." All we have a right to do is just to titter the final judgment--"beyond this limit neither thought nor imagination can pass." What the complex vision definitely denies to us, therefore, is the right to regard this thing, which is _no_ thing, with any emotion at all. The expression "unutterable mystery" is a misleading one because it appears to justify the emotions of awe and reverence. We have no right to regard this thin simulacrum, this mathematical formula, this stopping-place of thought, with any feelings of awe or reverence. We have not even a right to regard it with humorous contempt; for, being nothing at all, it is beneath contempt. Humanity has a right to indulge in that peculiar emotional attitude which is called "worship" towards either side of the ultimate duality. It has a right to worship, if it pleases--though to do so several attitudes of the complex vision must be outraged and suppressed--the resistant power of malice. It has even a right to worship the universe, that turbulent arena of these primal antagonists. What it has no right to worship is the "unutterable mystery" _behind the universe_; for the simple reason that the universe is unfathomable. Human thought has its stopping-place. The universe is unfathomable. Human thought has a definite limit. The universe has no limit. The universe is "unutterably mysterious"; and so also is the human soul; but as far as the soul's complex vision is concerned there can be no reality "behind the appearances of things" except the reality of the soul itself. Thus there is no "parent" of man and of the universe. But "the immortal companions" of men are implied from man's most intimate experiences of life. For if there were no invisible watchers, no arbiters, no standards, no tests, no patterns, no ideals; our complex vision, in regard to certain basic attributes, would be refuted and negated. Every soul which exists must be thought of as possessing the attribute of "emotion" with its duality of love and malice, the attribute of "taste" with its duality of beauty and hideousness, of conscience with its duality of good and evil, and the attribute of "reason" with its duality of the true and the false. Every one of these basic attributes would be reduced to a suicidal confusion of absolute sceptical subjectivity if it could not have faith in some objective reality to which it can appeal.
