You: He could know many more things that he could do than maybe I could do, but does it make me smarter because I am the one actually able to do it?
Me: No
You: You're wrong
Me: Why does being physically able to do something make you any smarter than someone who understands how but can't?
I don't see the confusion. Are you speaking in terms of physical ability or mental ability? You can know that solving a Rubik's Cube involves pattern recognition without being able to figure out the steps, but then again, that's not knowing how - therefore you aren't 'smarter' than the guy that can actually do it. You can also know the exact steps necessary in order to solve one, but be a quadriplegic - therefore you are smarter than the healthy guy that doesn't have a clue.
