I hold that the propositions embodied in natural science are not derived by any definite rule from the data of experience, and that they can neither be verified nor falsified by experience according to any definite rule.
Michael PolanyiWe could not, for example, arrive at a principle like that of entropy without introducing some additional principle, such as randomness, to this topography.
Michael PolanyiTo try to reform all the power structures at once would leave us with no power structure to use in our project. In any case, we will be able to see that absolute moral renewal could be attempted only by an absolute power and that a tyrannous force such as this must destroy the whole moral life of man, not renew it.
Michael PolanyiWe do not accept a religion because it offers us certain rewards. The only thing that a religion can offer us is to be just what it, in itself, is: a greater meaning in ourselves, in our lives, and in our grasp of the nature of things...a religion exists for us only if, like a piece of poetry, it carries us away. It is not in any sense a 'hypothesis.
Michael PolanyiWhile tacit knowledge can be possessed by itself, explicit knowledge must rely on being tacitly understood and applied. Hence all knowledge is either tacit or rooted in tacit knowledge. A wholly explicit knowledge is unthinkable.
Michael PolanyiThe amount of knowledge which we can justify from evidence directly available to us can never be large. The overwhelming proportion of our factual beliefs continue therefore to be held at second hand through trusting others, and in the great majority of cases our trust is placed in the authority of comparatively few people of widely acknowledged standing.
