In Natural Goodness, Philippa Foot is haunted by Wittgenstein:
“For one recalls [which she does several times in her short book] Wittgenstein's famous death-bed insistence that he had had a wonderful life....Interpreted in terms of happy states of mind it would, however, have been very puzzling indeed if a life as troubled as his had been described as a good life. What Wittgenstein said rang true because of
the things he had done, with rare passion and genius, and especially
on account of his philosophy. Did he not say elsewhere ‘The joy
of my thoughts is the joy of my own strange life’?”
(p. 85 of NG, quoting Norman Malcolm quoting LW)
