Abstract

"This work springs from a conviction of the unity of nature, expressed here in a single principle. In its earliest form this conviction was merely the sense of a hidden unity of form in nature, which the intellect had not yet identified. At that stage it had little value, except in creating the need to find a rational justification for the a-rational feeling. Soon I realised that the discovery of a universal form of process was hindered by the intellectual separation of the processes of subjective experience from those of the external world. It was necessary to bring into closer relation the scientific conception of the forms of external nature and the subjective sense of the forms of experience. This in turn led to the recognition that the methods of exact science had paid inadequate attention to the irreversible or one-way character of process, which is unmistakable in the subjective realm, but is also evident in many inorganic and organic processes, such as those do which form is developed. I expressed this view in a sketch of the outlook of the sciences, entitled Archimedes, or the Future of Physics (1927). The next step was the observation that one principle only could account for the development of regular spatial forms: the principle that asymmetry decreases in isolable processes. This concept of one-way process appeared to me to be the most general conception of spatial process conceivable at the present time, so that all other types of process should be capable of being represented as special cases. I called it the Unitary Principle and determined to use it as the basis of a comprehensive scientific method."--The preface.
