“Having no use” for something has less to do with that thing’s uselessness than the quality of one’s own understanding and hopes. To the extent one understands, everything may be relevant, and to the degree one hopes everything may be problematic.
As we realize that everything, every thing and everyone is potentially relevant and problematic we lose the capacity for violence — and for this reason understanding and hope should be tempered by humility. We are all living things, after all, and we must eat, defend ourselves, and fight for what matters to us. To deny this fact completely is hubris, but to surrender to this fact is base.
To aspire to humanity is to live suspended.
