Abstract

The problem of the nature and scope of Causation has again been raised into prominence by recent research on atomic structures and processes, the result being that many physicists maintain that the causational principle must now be restricted to macroscopic changes regarded as the averaged outcome of microscopic events, each of which alone may not be causally determined, or at least not completely so. Of this markedly new departure Professor Eddington is perhaps the best-known advocate. “Physics,” he asserts, “is no longer pledged to a scheme of deterministic law; the search for a scheme of strictly causal law not practical politics.” But the issue concerns not Physics only, for Dr. Eddington at once proceeds to interpret his viewpoint by contending that “science withdraws its opposition to free will”; and thus the realms of consciousness and conduct are once more brought into intimate connection with the realm of physical phenomena. It must of course be recognized that the question still remains highly debatable; for, as Sir Oliver Lodge has recently urged, “break down causality, and we are left with chance. That is wholly unsatisfactory. Chance is no solution”; and he likewise expands his survey beyond Physics by adding, “not in that way would I aim at freedom.” It is scarcely necessary to refer to current controversy in the biological sphere, between those who regard living processes as falling, if only to some degree, outside the domain of causal action, and those who insist that such action is universal, the indubitable proof of their position being prevented only by the difficulties of investigation.
