True courage is a bit like a good coffee in the cafeteria – you think you just need a shot of espresso, but you find there's a whole complex roast behind it. It's not merely flexing muscle, though that does show up when you confront a hostile question. What really matters, if we dig into the old footnotes from that 1983 metaethics paper, is whether you’re willing to accept the uncertainty of the argument without turning it into a spectacle. The real test is, can you stand in that silence and still say, “I’ve got no answer yet” without feeling the need to shout?
