Wittgensteinian readings of Being and Time, and of the source of the intelligibility of Dasein's world, in terms of language and the average everyday public practices of das Man are partly right and partly wrong. They are right in correcting overly individualist and existentialist readings of Heidegger. But they are wrong in making Heidegger into a proponent of language or everydayness as the final word on intelligibility and the way the world is disclosed to us. The everydayness of das Man and language are partial sources of intelligibility but only insofar as they are comprehended within the greater unitary structure of care and temporality. Care and temporality constitute the foundational underpinnings for disclosure and the intelligibility of"that wherein Dasein dwells."
