This inherent contradiction may be stated, in the terms of our definition, thus: we are willing for an opposite view to exist _only_ when we are not entirely convinced that our own view is true. The real belief in absolute truth is a missionary state of mind, and carries with it the faith that truth is the one thing worth having. In our day, the infinite variety of ideas which custom does not stale, has long forced itself upon our attention. In consequence we no longer share the faith of Plato that knowledge, as distinct from opinion, can be secured. We cannot believe anything quite as firmly as the mediæval Catholic believed in an eternal church independent of argument, or indeed of humanity. If we could, we should be as intolerant as Billy Sunday, whom "the pale cast of thought" has never tinged, and, if we were metaphysicians, should go up and down the world preaching the dangers of neo-realism, as the evangelist fulminates against the blasphemy of biological evolution. But Billy Sunday is an inverted anachronism; it is not in the power of a modern of the _commencement de siècle_ to recapture his fine careless rapture. If this be true, if we have grown too modest to declare the eternal constitution of the universe, what degree of conviction and what quality of tolerance are left us? The first answer is, that we may be willing to admit a view differing from our own because we realize that both may be right. But such a realization, if it is to be more than verbal politeness, implies that the difference is only partial or nominal, and consequently that my opponent's error does not shut him out from acknowledging my truth. I may be a woman suffragist, and yet be tolerant of the views of a friend who opposes suffrage, not on grounds of sex, but because he believes that the suffrage is already too wide, requiring restriction rather than enlargement. If I also am in theory an aristocrat, I can admit the notion that both of us are in a measure right. But the only real tests of tolerance are the far more common cases, in which, if I am right, you must be wrong. Present species are or are not the result of development or special creation; the world is or is not an intelligible order; our individual personalities do or do not survive bodily death. We cannot be content here to fall back on a different statement of the problem. When we say: "Oh, yes, we both believe in God; to me he is Life Force; to you, Jehovah," we know in our hearts that we are simply conniving at the draining of all definite meaning from the word, in order to confuse the issue and keep the peace. The one thing needful is, not that we should find blanket terms under which we seem to agree, but that we should drag our disagreement into the clearest possible light, and so find out what we are talking about. Not only our language, but our intelligence suffers from preferring vague unity to distinct differentiation.
