The book of Bergson (1) underlying the present study appeared in 1896. It is entitled “Matter and Memory” and is a philosophical disquisition into the relation and mutual limitations of organic life and inert matter. Bergson proposes to deal with this very general problem under the special aspect of a theory of the functioning of the human brain and the mechanism of ordinary memory. Such use of the inductive method, which starts from a special problem in order to arrive at results that might be generalized later, might endear him to the exact scientist who has a healthy skepticism toward pure generalities. But let us for a moment remain in the realm of generalities in order to better circumscribe the subject: Few people would agree to an entirely mechanistic interpretation of organic life; hence there should be some point in biology at which the deviations from pure mechanism appear explicitly and in their fulness. For the present we shall adopt an intentionally oversimplified mode of expression. Let us say that mechanistic description is causal and that as our analysis progresses we must eventually arrive at a point where we can no longer trace the causal chains in their entirety. At that point we must replace causal “classical” physics by quantum mechanics and form our pictures of microscopic realities of organic matter in terms of the latter. Some of the pertinent problems have been pointed out by the present writer (4) among others, following earlier suggestions by Niels Bohr (2). Suffice it here to say that certain processes of the atomic scale going on in a complex system such as the organic tissue essentially escape detailed observation that would allow us to determine the continuity of an entirely causal nexus. It is possible to make such observations, but they result in physical destruction of the very coherence of the organic tissue upon which the biological functioning depends. Bohr describes this condition by the term “generalized complementarity.” We cannot enter into a discussion of these problems here; let us adopt deliberately the oversimplified and somewhat vague expression that at some point indeterminacies become significant in the microscopic processes that take place in the organic body. We shall try to limit ourselves in this paper to the simplistic notion of a multiplicity of indeterminate events inserted (in a very crude manner of speaking) into the play of molecular reactions that constitute the functioning of the organism from the viewpoint of the physicist and chemist.
