The following is a passage which speaks for itself. I cannot add nor take from it without weakening it. The idea that it encapsulates is something that strikes me as important, and I figured you may perceive it in the same way. It is from Stephen Erikson’s Toll the Hounds and I hope you find it enlightening in some way.
“My finest student? A young man, physically perfect. To look upon him was to see a duellist by any known measure. His discipline was a source of awe; his form was elegance personified. He could snuff a dozen candles in successive lunges, each lunge identical to the one preceding it. He could spear a buzzing fly. Within two years I could do nothing more for him for he had passed my own skill.
I was, alas, not there to witness his first duel, but it was described to me in detail. For all his talent, his perfection of form, for all his precision, his muscle memory, he revealed one and only one flaw.
He was incapable of fighting a real person. A foe of middling skill can be profoundly dangerous, in that clumsiness can surprise, ill preparation can confound brilliant skills of defence. The very unpredictability of a real opponent in a life and death struggle served my finest student with a final lesson.
It is said that the duel lasted a dozen heartbeats. From that day forward, my philosophy of instruction changed. Form is all very well, repetition ever essential, but actual blood-touch practice must begin within the first week of instruction. To be a duellist, one must duel. The hardest thing to teach is how to survive.”
