Dear John, list: Thank you for your statement but I'm not sure to what you are objecting.
Is it that the pragmatic maxim does not achieve the stated goal: "Each abstraction is either pronounced to be gibberish or is provided with a plain, practical definition." ...or that *this* pragmatic maxim ("Consider what effects...") does not? That is, are you saying that this one, ("Consider...") is nominalist in essence? What then, in your opinion, is the best pragmatic maxim that does justice to the purposes of pragmaticism? Which maxim best summarizes the logic of abduction? Which is the strongest argument? Is CP 5.189 not a pragmatic maxim; the best one? Thank you for your time.
