Animals exist in a world of struggle,
in which all that matters is one
result -- continuity of self and the
genetic line
Sapient beings dwell in nests of
obligations, to their colleagues,
patrons, clients, and ideals.
They may choose fealty to a cause,
to a godhead or philosophy, or to the
civilization that enabled them to
avoid living animal lives.
Knots of allegiance cling to us all,
even after treading down the Path of
Redemption.
Still, children of exile, remember
this ---
--- in the long run, the Universe
as a whole owes you nothing
