In his book 'Philosophy and the Mirror of Nature' Richard Rorty claims that some projects of philosophy or philosophy -as theory of knowledge, as he calls it, are optional and contingent. In the first place, the author tries to show Rorty's strategy which leads him to that thesis. Secondly, he attempts to critically investigate his 'crucial premise' according to which the adequate model of knowledge is not a model of 'confrontation' but of 'conversation'. In the end he also considers a perspective in which both models do not rule out each other, but become two equally important aspects of knowledge.
