Yes but how is it senseing the real, if are minds are purely material?
Our minds are not merely physical. We have the matter that comprises the physical brain, but “mind” includes the soul also, that is the intellect and will. The soul is not material.
Yes.
Then the “noise” is the disturbed air molecules,and it would indeed be “made” by the falling tree even if no one was there to “interpret” it as noise.
If a man talks in the woods and there is no woman to hear him, is he still wrong?
The only true reality is a spiritual one. Everything here is dependent on things like perceivable wavelengths, quantum probabilities and subjective experiences that we convince ourselves are objective.
Yes, but the perception of red is really how the brain unscrambles certain wavelengths of light. For example, the wavelength range that I see as red, you could perceive as purple (in my world). But since you grew up with purple being red, that would BE red for you. I can never look at someone else and know if they are percieving the same “COLOR” as I am, merely because their brain might interpret it differently but the word association is the same with whatever color they percieve in that wavelength range.
Yes, absolutely. Red is a word. We can’t know something without having a word for it. Some cultures like the Piraha have no words for colours.
There have been some studies done (at least one at any rate) on how people ascribe color to various works of art that are physically colorless (like symphonies). They found correlations between the ascription of certain colors and the works of art. This is mentioned in a book called “Art in Action”
