Lately I have been thinking about the difference between learning things and learning about things.
The difference operates on several levels, I think. In the end, learning things is effortful but rewarding, while learning about things is effortless and much more fun.
I have always held that, if you cannot reconstruct a Chemistry equation from scratch, from pure reasoning, you really do not know the thing at all: You just know about it. (Yes, I am thinking at the moment about the Gas Laws.)
Had I a hundred free hours today, I would go on about the implications for psychotherapy, blogging, education, God, and life in general. But I don't.
