Well, I mean, neither is non-group think.

That's the issue. No one can really systematize "discovery".

How many "group thinkers", "creatives", "non-group thinkers", "nihilists", "anarchists", "contemplatives" in the last - say, 500 years, 5000 years, whatever - have been occasioned by the fall of an Apple? Or the fall of a branch? Or a leaf? Or what have you?

Why did it spark a new flame in the mind of Newton? Science can't explain. If we could, we'd teach everyone to be that sort of contemplative.
