Abstract
Both Polanyi and many of his interpreters saw the implications of tacit knowing for restoring the Augustinian principle that faith precedes understanding. Polanyi’s contribution to the rediscovery of the essential role of faith in the achievement of knowledge has, however, had a limited impact in science, philosophy, and in Christian theology. Polanyi’s epistemological contribution, nevertheless, is much more than a restoration and a reformulation of tradition. Tacit knowing provides a new vehicle for deeper interpersonal understanding.
