Sport works on the nerves- and wakes the tribal instinct. I would like to think I watch tennis as a display of skills- and am indifferent as to the outcome of matches- but the fact is I did want Roger to win.
Or- to use less regenerate language- to "beat" Rafa. Not very high consciousness: to enjoy watching one man "beat" another. And not so far from what went on in the Roman circuses.
Here's the essential difference between sport and art- that no-one ever came out of the theatre wanting to beat someone up because Lear and Cordelia are dead.
