Poets are apt to formalise their ideas in twisted syntax and clanging words, but I would rather chat my ideas to some wandering mythical shepherd and have them turn up again carved into some rude block on a sheer mountain top. But when the twisting is topological enough and the clanging bright enough, then there may be a medium that the shepherd can't carry, as though some mathematical expression from one age shown to a former. So some ideas might depend on the teaching of that expressivity.
