Being human as distinct from merely mortal is to be native to a complex social world in which everything matters, but where your knowledge is confined to a sliver, the direct out-facing view from a single point on a single determinate and homogeneous trajectory. And even your your own relatively constant internal world is experienced in the same limited and perspectival way. It is about a particular setting of awareness which is such that it can only directly grasp a small fraction of what it needs to, or would like to, know. It is a thrownness, indeed, but not into a barren rock-strewn landscape, not even a lush natural landscape, or a Greek amphitheatre, but a social landscape of multiple parallaxes and foreshortenings, of calls and responses - whatever that all might ultimately mean. It is also too simple to call it a world of semblables, as if they were merely disquieting objects of some kind, obliquely challenging to the self, and you could puff at your pipe and meditate on "the problem of other minds". But if not semblables, then what? Alter-egos? Well, no, because you are not fully formed apart from your relationships to social fact which you in no way understand, but which makes un-evadable demands on you, demands which precede and succeed you. Whatever you do, whether comporting a belief free-will or not, whether a speech act or the most intimate personal realisation, is already a response.
