Let us give a counterpart explanation of causation. My first problem set is in the extension of F. Outlining the Frege-Mill theory, Socrates is mortal. I have to capture access problems. I have to show that there can be a model in which Socrates is true. I will go to work with the whole part in my head, the sum of which is null.
Let b be a part of itself, and let q be a part of itself. Let us consider what we get if we move to a polar framework. Moving between the biggest poles, we have a path between variables. For higher arities, our polar journeys make stops. Making stops is a matter of having a certain sort of constitution, together with a host of environmental constraints.
But this cannot be. For if the Frege-Mill theory is true, then the problem set is not in the extension of F, and Socrates may not be mortal in this scenario. Therefore our counterpart explanation has failed.
