A basic argument for panpsychism, as Strawson presents it, is that we know we are personally conscious.
Well, I know personally that I have a conscious mind. I experience myself directly.
However, I am incapable of experiencing another mind or proving that it exists.
You could be sitting across from me and still could not know or prove that you have a conscious mind.
I can measure your brain activity, but that isn't the same exact thing.
