However the novel features a twist ending which makes it clear that Martin actually drowned shortly after his ship was sunk, and this changes the work into an allegory of purgatory and damnation.
When asked about his intentions in Pincher Martin by Archie Campbell in a BBC interview shortly after the novel's appearance, Golding gave a clear and unambiguous paraphrase of the novel's theme:
'To achieve salvation, individuality--the persona--must be destroyed. But suppose the man is nothing but greed? His original spirit, God-given, the Scintillans Dei, is hopelessly obscured by his thirst for separate individual life. What can he do at death but refuse to be destroyed? Inhabit a world he invents from half-remembered scraps of physical life, a rock which is nothing but the memory of an aching tooth-ache? To a man greedy for life, tooth-ache is preferable to extinction, and that is the terrible secret of purgatory, it is all the world that the God-resisting soul cannot give up.'
