In [1] Michael Polanyi argues that in order to understand how scientists come to recognize problems as problems, we must invoke a concept of “tacit knowing.” Tacit knowledge is a kind of knowledge of which we are aware but which cannot be made explicit. Polanyi argues that a paradox discussed in the Meno cannot be solved without appeal to this notion of tacit knowledge. Here I want to argue, quite simply, that Polanyi's formulation of the “paradox” can be easily subverted (...) without an appeal to tacit knowing. Polanyi puts the paradox thus:... to search for the solution of a problem is an absurdity; for either you know what you are looking for, and then there is no problem; or you do not know what you are looking for, and then you cannot expect to find anything.
