The Unaccountable Element in Science1

Michael Polanyia1

a1 Merton College, Oxford.

I hope that it will become clear in the course of this paper what I mean by calling some elements of science unaccountable. Let me now say only that I shall speak of the contributions made to scientific thought by acts of personal judgment which cannot be replaced by the operation of explicit reasoning. I shall try to show that such tacit operations play a decisive part not only in the discovery, but in the very holding of scientific knowledge. I shall outline the structure of these acts and indicate to what extent this structure offers a justification for relying on such acts.
