Straying off topic a little again...
My maths/climbing analogy as regards ethics and that was inspired by Keats' Ode On A Gritstone Problem which finishes
O Attic shape! Fair attitude! with brede
Of smears and slopers overwrought,
With forest branches and the trodden weed;
Thou, silent form, dost tease us out of thought
As doth eternity: Cold Pastoral!
When old age shall this generation waste,
Thou shalt remain, in midst of other woe
Than ours, a friend to man, to whom thou say'st,
"Beauty is truth, truth beauty," - that is all
Ye know on earth, and all ye need to know.
I've underlined the important bit. The beauty of finding a clean proof in maths or logic is comparable with the beauty of climbing a route in good style (as it is experienced by the climber/prover). Which brings us nicely back to downclimbing.
1. climbing goes up mostly
1.1 climbing that goes across is acceptable because it is not-down
2. it is the not-downness of climbing that is important
2.1 downclimbing is anti-climbing
3. when climbing is achieved by enough downclimbing as to be worth mentioning, then it is no longer proper climbing.
Now, I've successfully put 8a.nu into bed with Keats and Wittgenstein. All that remains is to get Simon Cowell a job as a route setter and the apocalypse can begin as planned.
