Welcome back, bbarr, I hope you and yours are all good!
Edit: “Well, I think your mind exists. Either your mind exists beyond mine, or it doesn't. If it does, your question is answered.”
I understand both your perspective and the logic of your argument. However methinks our case is not exhausted with a dilemma; instead of this approach, I am usi own this point of attention firmly established, your dualism will disappear on the spot
😵
You too, and it's good to be back!
If, as you say, my mind can
successfully refer to yours, then there is something other than my mind, namely, that to which I'm referring. The success conditions for reference are that something in the world is picked out, that the objects/properties I'm representing exist/are instantiated. So, if reference succeeds, then your original challenge has been met.
Of course I employ concepts in successfully referring to your mind. Mental representations are concepts, so of course my representation of your mind is conceptually articulated. It would have to be, in order for that representation to participate in propositional attitudes like thoughts and beliefs. Propositional attitudes are partially individuated by their content, and their content consists of concepts and their formal relations. But nothing follows from this about the existence of the putative referents of concepts or propositions.
To think otherwise is to commit the same fallacy at the heart of ontological arguments; the mistake of trying to read off metaphysical conclusions from premises regarding the conceptual content. It's just like the old saying that one shouldn't mistake the moon for the finger pointing at it. You're making a correlative error by inferring that because there is a pointing finger, there must be no actual moon!
Yes, I am familiar with constitutive and instantiated properties. An object X has P constitutively iff X is an X-type by virtue of having P. Instantiated properties are just the non-constitutive properties X also has.
Nagarjuna argues that since we can conceptualize objects differently, the set of properties that are constitutive or instantiated respectively can change. If I conceive of that as a chair, then 'sittable' may be constitutive and 'wooden' merely instantiated. If I conceive of that as a former tree, then 'wooden' may be constitutive and 'sittable' merely instantiated.
But, so what? I can conceive of your mind in a variety of ways, and for each of these ways my representation of your mind may be more or less accurate depending upon the correspondence between the properties I take your mind to have and the properties your mind actually has. But if I represent your mind in a fine-grained enough way to successfully refer to your mind, then it
doesn't at all matter what properties I must take as constitutive or instantiated.
This should be clear. After all, it's not part of the content of my conception of your mind that this or that property has itself a further property of being constitutive or instantiated. My representations may have modal entailments, but that doesn't mean that these entailments are part of their semantic content or sense. I mean, if I conceive of that thing as a zebra, then I am thereby committed to it not being a cleverly painted horse. But it simply doesn't follow that 'not a cleverly painted horse' is part of semantic content of the concept 'zebra'. If it did follow, then nobody could ever learn a concept, since the semantic content of any concept would consist of an infinite number of distinct propositions. Zebras aren't asteroids or rings of power either.
In any case, you should be suspicious of an argument that starts with a distinction, then denies that that distinction has any ontological import, then concludes with a claim about what actually exists! That's rhetorical hocus-pocus.
