What we're disagreeing on here is either how to define thought or how the
brain works. I just stored my books away for a while to move my office from
one place to another, but I will give you the quotes from neurologists as
soon as I have access again. Meanwhile, I think we may just be talking
about different things.
Categorizing, to my mind, is a form of thought. Perception does not take
place in the absence of it. Philosophical thought is something else
entirely. It means wondering about what you saw after the fact. The act of
categorization is so elementary and natural we are seldom aware of doing it.
But the reason we ignore most of what we see when driving (for example) is
because we have already seen it before and categorized it as something we
don't need to pay attention to. But that doesn't mean we don't see it.
With a little effort, the entire trip can be summoned up and reconstructed.
All of perception is that way. What you are calling seeing, I believe, is
perceptions that we pay attention to. The ones we are "conscious" of. But
a lot more is flooding our brains with signals than we are conscious of. We
simply choose to ignore one signal in order to pay more attention to
another. When I read a book, I sometimes don't hear people talking to me (a
trait my family often complains about). But that doesn't mean the sound was
not received and processed by my brain. It just took me a little while to
remove my attention from where it was fixed and turn it toward a competing
If you only regard the thoughts generated by what you are paying attention
to as "thought," then I might agree with that. But I consider what my brain
is processing through my five senses without fixing my attention on it to be
perception and thought as well. They both influence how I react to things.
Any sudden change in my environment can trigger a refocusing of my
attention. That's because my brain was keeping track of what was going on
around me but didn't see a need to fucus on it. It was thinking about it,
but choosing to ignore it.
If you're not calling that "thinking," I can work with that. It just wasn't
what I was talking about.
