Scot asked:

God designed humans to be similar to each other, we all have arms, legs, a brain, and hair. But they
are all unique, no eyeball is the same color and definitely no two people look alike. If these minor
differences are present, then why wouldn't our sight, smell, and hearing work slightly different from
each other? Is my "blue" the same as your "blue"? Is my "F sharp" the same as your "F sharp"?

============

It's probably just as you say. In philosophy, this is the problem of "qualia". My problem is that I could
write 50 pages without blinking an eyelid on this topic, and yet everything I might write would surely
be contentious, because it's still a red hot issue at present. So my suggestion is that you consult a
philosophical dictionary under the heading of "qualia" and go on from there. Have fun!
