Identifying my errors relieves me of the awful burden of omniscience. I stole that form John McIntyre's blog, which I read with relish: http://twitter.com/johnemcintyre
Thursday in Humanities class, my attentive students pointed out a couple errors on hand-outs, etc. I beg fallibility. I'm not God. I'm just tryin' to teach some of what I've learned.
I love this attitude...can you imagine the awful burden of omniscience? I suppose when we start teaching, we think we have to know all. It's so nice to be old enough not to worry about that.
