The Experimental Epistemology of Walter S. McCulloch a Minimalistic Interpretation

Abstract

When cybernetics entered the scene during the forties, high ambitions immediately arose and quite unusual claims were made as compared to those of traditional epistemology: cybernetics would do away with the distinction between ’mind’ and ’body’ (Papert, 1965); it would bring a new interpretation, through the artefact, of the Kantian synthetic a priori¹; cybernetics would give, following Turing’s approach of computability, a mechanistic sense to Kantian schematism (Dupuy, 1985, pp. 105–106).

In this text we shall analyse the statute of that sort of claims. In other words, we shall show what is the relation between epistemological questions which we call classical or theoretical and those occurring within cybernetics, and more in particular in the work of McCulloch. McCulloch was clearly an advocate of experimental epistemology. He emphasized, in contrast with Kant for instance, that the experimental inquiry into the functioning, the emergence and the consequences of knowledge can be important for epistemology in general. Furthermore, we shall inquire how McCulloch’s experimental epistemology may be relevant to classical epistemology.²

Firstly, we shall discuss the position of McCulloch within cybernetics. Secondly, we shall deal with the meaning of his net of formal neurons and with the meaning of the heterarchic nets. This will allow finally us to illustrate in what sense McCulloch is to be situated outside first cybernetics and how he anticipates second order cybernetics. It will also allow us to show that the experimental epistemology which he defends can get an interpretation beyond the frame of a traditional reductionism. What we are proposing here is a minimalistic interpretation: the epistemology, insofar as it tends to be experimental, doesn’t have to serve as a support for reductionism, but rather aims at pointing out concrete limits within which a theoretical epistemology can be developed.
