Quote in context:
In 1945-46, Camus argued that, he says, 'I'm not a philosopher because I don't believe sufficiently in reason to sign up to a thought that would be seen as being philosophically systematic'. He says, 'What interests me is to know how one is to live, and this is more precisely how one is to live when one neither believes in God, nor totally in reason.'Looks like I really should go read The Myth of Sisyphus...
