Your personality, your thoughts. The ideas in your head, logic and mathematics, all immaterial, all affect us in huge ways on a daily basis.
I'm afraid you find yourself without reasonable argument.
You are merely quoting abstract concepts, none of which interact with us at all.
You don't interact with "maths".
You DO interact with the visual stimuli of the lines, drawings etc on the paper, crunch away in your head (all of which is a physical process), and arrive at an answer that you then physically visualise and probably store to memory, and probably write down.
The same with logic.
It is a tool - a concept.
We do not "interact" with it in any way.
These two words are merely abstract concepts to describe the physical thought process that goes on in the brain to arrive at the right answer.
We are taught that 1+1=2.
We see the physical stimuli of the letters either on the paper, the board etc. We get the physical stimuli of the teacher telling us etc.
So, in simple terms, our brain builds a physical connection in the brain such that when we see 1+1 again we know that the answer is 2.
"Maths" is an abstract concept - but at no point do we interact with it.
"Personality" is immaterial - but it is also not something that interacts. Personality is nothing more than a concept. It is the way, peculiar to each individual, in which our brain crunches all the inputs to achieve the outputs.
The inputs are physical.
The outputs are physical.
The processing is physical. It is this processing, peculiar to each of us, that is our personality.
There is no interaction with the immaterial at any point.
The fact that everyone processes the same inputs to achieve different outputs is what gives us our unique personality - but it is not something that interacts.
If you disagree with any of this, please detail to me exactly how it is that you interact with logic, with mathematics, with personality, with any of your examples.
