 Binswanger's "Dream and Existence" — which was translated from German into French by Michel Foucault who added a substantial essay-introduction — highlighted in similar fashion the necessity of "steeping oneself in the manifest content of the dream - which, since Freud's epoch-making postulate concerning the reconstruction of latent thoughts, has in modern times receded all to[o] far into the background".Eugène Minkowski had earlier introduced Binswanger's ideas into France, influencing thereby among others the early work of Jacques Lacan.In his study of existentialism, his most famous subject was Ellen West, a deeply troubled patient whose case-study was translated into English for the 1958 volume "Existence".
