If civilisation is to survive, if the emergent civilisation is to achieve the fulfilment of its potentialities, the coming age must be an age of spiritual as well as social integration.

Today the human mind is torn and divided between positivism and irrationalism. The endeavours of pragmatism succeeded in making important discoveries concerning a number of basic attitudes in thought and morality, and in what might be called the sociology of knowledge. As a universal system of knowledge and life, as a philosophy, however, pragmatism has been a failure.

What is essentially needed is a renewal of metaphysics. The conceptions of modern science—the unification of matter and energy, physical indeterminism, the notion of space-time, the new reality recognised both as to quality and duration—are invaluable means of deciphering material phenomena. A cosmos of electrons and stars in which the stars are the heavenly laboratories of elements, subjected everywhere to genesis and transmutation, a universe which is finite but whose limits cannot be attained because of the curvation of space, and which dynamically evolves in a definite direction, namely toward the highest forms of individuation and concentration and toward a simultaneous degradation of the quality of its total energy—all this is external description and scientific imagery rather than ontological insight. Such knowledge can never directly serve the purpose of any philosophical or metaphysical extrapolations. Yet all this constitutes at the same time a basic representation of the world incomparably more favourable to the edification of a philosophy of nature and more open to the deepening labour of metaphysical reason than the old Newtonian physics.
