Language Lost and Found takes as its starting-point Iris Murdoch’s claim that we have suffered a general loss of concepts. By means of a thorough reading of Iris Murdoch’s philosophy in the light of this difficulty, it offers a detailed examination of the problem of linguistic community and the roots of the thought that some philosophical problems arise due to our having lost the sense of our own language. But it is also a call for a radical reconsideration of how philosophy and literature relate to each other on a general level and in Murdoch’s authorship in particular.
