Michael Polanyi's thought has received increasing attention from theologians over the last few years. He offers both an historical and a critical analysis of the intellectual roots of contemporary Western culture. One aspect of this is his diagnosis of Locke's contribution to the emergence in Western epistemological theory of the supremacy of demonstrative knowledge over faith. This is reported, for instance, by Professor Thomas Torrance, quoting, first, this passage from Locke's Third Letter on Toleration:
For whatever is not capable of demonstration … is not, unless it be self-evident, capable to produce knowledge, how well grounded and great soever the assurance of faith may be wherewith it is received; but faith it is still, and not knowledge; persuasion, and not certainty. This is the highest the nature of the thing will permit us to go in matters of revealed religion, which are therefore called matters of faith; a persuasion of our own minds, short of knowledge, is the last result that determines us in such truths.
