: If it’s your position that the brain’s cortex = cognitive states, then ‘cortex’ and ‘cognitive states’ are logically equivalent terms and mean exactly the same thing.

: So when I perceive a red square, my cortex IS red and square and exists only as a first-person fact. This is a radical idealist’s view.

<JT>You need to be more precise in your wording. When you perceive a red square, your cortex remains gray and squishy.</JT>

: If this is not how you understand it, and the terms are not logically identical, you will need to explain in what ontological sense ‘cortex’ and ‘cognitive states’ differ. You have not done this.

<JT>You're trying to make me sound ridiculous by dropping the context in which we speak. Of course my brain isn't a red apple when I look at or imagine a red apple! I can't reach up into my skull and expect to grab fruit. What I believe is that when you perceive or imagine something, there is a specific, corresponding physical change in your brain, and that without that physical change perception, thought, consciousness, are all impossible.</JT>
