I liked this bit from Seneca:
Nothing, however outstanding and however helpful, will ever give me any pleasure if the knowledge is to be for my benefit alone. If wisdom were offered to me on the one condition that I should keep it shut away and not divulge it to anyone, I should reject it.
I agree with this idea, and I think that it informs my decision to be a teacher and is part of the joy I find in blogging, not to say that I’m a dispenser of wisdom, exactly, but that I need an outlet of some sort for sharing the things I learn. I’m happy learning things on my own; I always liked school but don’t feel that I need it to learn things and often think I can learn better by myself. But what to do with knowledge I’ve gained? There’s something depressing about learning things and doing nothing with them. I think I’ve said this before, but still, it doesn’t hurt to say it again: blogging is a wonderful way do something with all the books I read and the ideas I encounter.
