One of the most interesting and important 'concepts' in "Being and Time" is that of "Das Man", for which there is no exact English translation; different translations and commentators use different conventions. It is often translated as "the They" or "People" or "Anyone" but is more accurately translated as "One" (as in "'one' should always arrive on time"). "Das Man" derives from the impersonal singular pronoun "man" ('one', as distinct from 'I', or 'you', or 'he', or 'she', or 'they'). Both the German "man" and the English 'one' are neutral or indeterminate in respect of gender and, even, in a sense, of number, though both words suggest an unspecified, unspecifiable, indeterminate plurality. The semantic role of the word "man" in German is nearly identical to that of the word "one" in English.
