Some time ago, an Innocent Bystander, after glancing through a copy of Mind, asked me, ‘Why do philosophers talk so much about Games? Do they play them a lot or something?’
Well, why do they? Broadly, because they are often discussing situations where there are rules, but where we are not now sure why the rules have to be obeyed. Treating them as Rules of a Game fends oﬀ this problem for the time. And should it turn out that the reasons for playing games are in fact perfectly simple, it might even solve it completely.
