ABSTRACT
All the conflicting tendencies which characterise modern philosophy at large re-appear in the special field of the theory of value. By contrast, the theory of the former will seem abstract and ill-balanced to the adherents of the latter, as ignoring or depreciating through the device of opposing feeling to fact, or desire to truth, the metaphysical import of moral and religious experience. Philosophy of nature, thus, as it pushes on to fundamental problems, will always become philosophy of Religion, even when, as 'naturalism' or 'materialism', it condemns all religion as savage animism or effete superstition. When, it acts as 'positivism', it elevates philanthropy to the dignity of a 'religion of humanity'. When science becomes philosophy, or when the problems of philosophy come to be attempted on the basis of scientific theories, the horizon at once widens to the whole range of human experience, and troublesome questionings and misgivings come crowding in.
