The Sinthome (n.) is defined against the symptom. Unlike a symptom, which xxxx, a sinthome, for instance a tic, is a minimal, elementary language we compulsively repeat which is permeated with enjoyment. It is the atom of enjoyment.
A Sinthome (n.) is the meaningless habit — drugs, drink, a perversion — that a happily married man with a good job will risk everything for, since only there does he meet the density of being; without it his universe is empty.
A Sinthome (n.) is an atom of enjoyment — the minimal synthesis of language and enjoyment, a sign permeated with jouissance, like a tic we compulsively repeat.
A Sinthome (n.) is the symptom as our only substance — the knot of enjoyment by which we avoid madness, choosing something instead of nothing; analysis ends when you identify with it.
The Sinthome (n.) is a knot of enjoyment, not a bearer of meaning; overidentifying with it, as Rammstein does, undermines ideological identification.
