Do you lift a roof over your head
or is the lifting
roof enough?

Do any of them keep the rain out?

ABSURD, THE. A term used by existentialists to describe that which one might have thought to be amenable to reason but which turns out to be beyond the limits of rationality. For example, in Sartre’s philosophy the ‘original choice’ of one’s fundamental project is said to be ‘absurd’, since, although choices are normally made for reasons, this choice lies beyond reason because all reasons for choice are supposed to be grounded in one’s fundamental
project. Arguably, this case in fact shows that Sartre is mistaken in supposing that reasons for choice are themselves grounded in a choice; and one can argue that other cases which are supposed to involve experience of the ‘absurd’ are in fact a *reductio ad absurdum of the assumptions which produce this conclusion. The ‘absurd’ does not in fact play an essential role within existentialist philosophy; but it is an important aspect of the broader cultural context of existentialism, for example in the ‘theatre of the absurd’, as exemplified by the plays of Samuel Beckett.
