We experience thoughts therefore they exists.
Perhaps, but we wouldn’t dare say that they “exist” in the same manner as a being. Thoughts, ideas, and all such abstractions are essences (or form, if you like); but they if they are soley essences then they cannot have being unless the essence was existence. But such is not the case for all things except the one of actus purus.
But something which exists must be a substance.
In the sense of them being a being, sure. But that which is soley essence does not
actually exist; they do not possess the same reality as you, me, or anything with being because we posses actualization in our essence, thus giving us existence. Soley essence is merely potentiality in that something may exist with that given essence but are not (such is the nature of definitions; they’re application is independent of the defined subjects existence, yet if the definition is met, the subject exists). So no, ideas do not “exist” really, though they do posses form or essencs which are immaterial and insubstantial realities; they may, therefore, only be possesed and “interacted with” by that which itself is immaterial in some way. I believe @Gorgias would call that the “soul”, though its nature I’m unfamiliar with, so comment on this part is sadly beyond my qualifications. In anycase, if I’m not mistaken, even a “spiritual” entity would be immaterial yet posses a substance of some sort, so even the immaterial could be subdivided.
Moreover we distinguish thoughts therefore they must have forms. We couldn’t possibly communicate thoughts in the form of sentences if they didn’t have forms.
Agreed. Thoughts and ideas must be form itself in some way.
quaestio45:
For one, forms do not posess the ability of interaction, yet a spiritual entity can.
Mind has the ability to experience. Experience what? Material.
Are you saying that the mind is ultimately a form? For, if you were, I’d have to object to this the same way I objected above; forms in and of themselves do not really exist, therefore they are inert and cannot experience.
Mind and matter are different substances.
Fair enough… how does rebut my argument that there must be a division between the forms and a spiritual entity in substance? Unless you claim there is only “mind and matter” but then you’d have to elaborate on what you mean by mind. Is it form? If so, then my objection above follows.
I cannot follow you here (bold part).
Out of what? A lack of understanding or disagreement? If its the former, then I basically say that there is a distinction between forms and a spiritual entity (like the mind), and as such, if the mind need only be simple in spiritual substance, then it very much can be composed in the holdin of forms.
