Humphrey Lyttelton and philosophy

A nice observation from Kieran Healy on Crooked Timber:

I first came across Lyttelton not on Radio 4, but in Peter Winch’s The Idea of a Social Science and its Relation to Philosophy, of all places.

He pops up there in an anecdote showing why some kinds of social practice are in principle not amenable to precise predictions derived from some (putative) social physics. Lyttelton was once asked if he knew where jazz was going, and replied “If I knew where jazz was going, I’d be there already.”
