All you have done is explain that concepts are immaterial and actual objects aren’t. And that a mental image of a mother is material and is found within the brain and a concept of a mother is not and it’s dealt with by the soul.
Exactly. And the argument is solid, which is why it will not snap.
The ratio of a circle’s diameter to it’s circumference would remain true even if there were no material circles. These are our universals. Concepts on tbe other hand are different.
No, sir. Unlike percepts, which are particular,
concepts are universal. My concept of “circle” applies to
any circle, not just
this circle or
that circle.
A concept doesn’t exist without someone holding that idea in their head. Using their brain.
A concept doesn’t exist without someone holding that idea in his head. But NOT just using his brain, but using his
intellect, which is an immaterial power. If all that we have is a brain and no intellect, then we will not be different from brute animals. What makes us different from brute animals is not because we have brains and they don’t have any. In fact, some animals have bigger brains than we have. What makes us different is our possession of an intellect, which gives us the power of conceiving abstract and universal concepts.
But a concept is an idea and even if that idea is immaterial the idea can’t exist unless it’s perceived by someone.
Concepts are not perceived, but
conceived by the intellect. However, it is true that a concept does not exist unless it is conceived by someone that has an intellect.
And that perception, just like any other thoughts about mothers or hopes or cats and dogs or unicorns takes place in the material brain.
Our
conceptions (not perceptions), just like any other thoughts about mothers, etc., take place
in the intellect, which is a power of the soul. The brain, being a material organ, is incapable of performing immaterial operations, such as understanding universals, distinguishing truth from error, and deductive reasoning. These are all functions of the intellect, not of the brain.
All the evidence points to everything connected to human thought being produced by physical and chemical and electrical changes in all that wet meat between your ears.
What is being produced by physical, chemical and electrical changes in the brain, is not our thought or universal concept itself, but the material “images” (in the form of neural networks) that
represent the concepts in the intellect. Just as words and vocal sounds can represent a meaning, neural networks can represent concepts. However, just as the sound of a word is NOT the meaning of the word, so the neural network is not the concept it represents. Being material, our brains cannot produce concepts that are universally free of matter. They can only produce the particular neural networks that represent the concepts.
