Beckett's favourite word, 'perhaps'.

Terry Eagleton in the London Review of Books points out that Samuel Beckett  understood that one could live and write well only by preserving a secret compact with failure. 'Fail, fail better'.

He felt te fewer words you spin, the less likely you are to lie.  so he made guerrilla raids on the inarticulable.  Ceratainty with its crazed assurances. Instability may be a cause for comfort as well as distress. with their crazed assurances. Determinacy is what kills. Moreover, indeterminacy is a source of hope as well as scepticism

i mean feck the ineffable (the idea that is too great or extreme to be expressed in words) the one idea that drags itself along limping like some wounded mangy dog.
 Language must lend shape to truth without betraying its essential indeterminacy. In the Beckettian phrase, it must keep trying to fail better. Perhaps, that is why his favourite word was 'perhaps'.
