Sublimation (n.) is a defense mechanism whereby one satisfies an impulse with a socially acceptable substitute object.
Sublimation (n.) is best understood along the lines of kantian beauty, a free play of imagination and understanding in a purposiveness without purpose or a finality without end.
Sublimation (n.) is the redirecting of excess sexual energy toward non-sexual, socially acceptable artistic creation and intellectual work.
Sublimation (n.) is the best later mental trends can do with infantile wishes: fall in with their compelling force, or divert it to higher aims.
Sublimation (n.) shifts the instinct's aim beyond the reach of frustration; its joys are 'finer and higher', but they do not convulse the body, and only the gifted few can have them.
Sublimation (n.) may always pass through the ego: desire first turned back onto the self, then perhaps given a new aim.
Sublimation (n.) is a way out: the ideal heightens the ego's demands and favours repression, while sublimation meets those demands without repression.
Sublimation (n.) turns sexual impulses away from sexual aims toward others socially higher — an unstable arrangement, since the instincts are only half tamed.
Sublimation (n.) swaps a sexual aim for a social one, its kin, and is called higher because social aims are ranked above self-interested ones — but it can only take a fraction of the libido.
Sublimation (n.) is the sexual instinct's capacity to replace its immediate aim by other, more highly valued aims that are not sexual.
Sublimation (n.) has a limit, like a steam engine that cannot turn all its heat into work; most people still need some direct sexual satisfaction.
