Know how vs know what

I think he's proposing a basic question of "Intelligence vs. Common Sense"; that is, do you have more knowledge, but are unable to apply it all the time, or are you just able to do things, but are unsure as to the reasonings behind it? Personally, I carry far more intelligence than I do common sense. I know a lot about a lot, but when it comes to doing something, I take the directions out of my brain and think about it logically instead of being practical. Therefore, it sometimes takes me a while to do something that's pretty simple.

Jam it back in, in the dark.
