42. It is the same with love and wisdom, the only difference being that the substances and forms that are love and wisdom are not visible to our eyes as are the organs of our external senses. Still, no one can deny that those matters of love and wisdom that we call thoughts, perceptions, and feelings are substances and forms. They are not things that go floating out from nothing, remote from any functional and real substance and form that are their subjects. There are in fact countless substances and forms in the brain that serve as the homes of all the inner sensation that involves our discernment and volition.

What has just been said about our external senses points to the conclusion that all our feelings, perceptions, and thoughts in those substances and forms are not something they breathe out; they themselves are functional and substantial subjects. They do not emit anything, but simply undergo changes in response to the things that touch and affect them. There will be more later [210, 273] on these things that touch and affect them.

210. Since we can think about volition and discernment, about feeling and thought, and about charity and faith apart from the substantial realities that are their subjects, and since we have thought about them in this way, we have lost any appropriate concept of them, any realization that they refer to the states of substantial realities or forms. Exactly the same principle applies to sensations and actions, which are not things in the abstract apart from our sensory and motor organs. In the abstract, or apart from their organs, they are theoretical constructs only. They are like sight with no eye, hearing with no ear, taste with no tongue, and so on.
