It might seem odd that we remember Scott's failure more vividly than Amundsen's success, but really it's not that surprising. Scott's mistakes and pathetic end speak more eloquently to us about the human condition- it's "dying as an art" to quote Sylvia Plath. Or as Derek Mahon says, in his poem echoing the last words of Captain Oates, at the heart of the ridiculous there really was something sublime.
He takes leave of the earthly pantomime
Quietly, knowing it is time to go:-
‘I am just going outside and may be some time.’
At the heart of the ridiculous, the sublime.
