If someone extracts a pattern that, say, three arguments follow, which we can then call the "shape" of this kind of argument, which of the three arguments are you suggesting is imprecise? Or is your position that any actual argument which fits into any pattern at all is somehow imprecise? It's clear that we are miscommunicating regarding the meta vs object level of this essay, but I'm not sure exactly where the disconnect lies.
