Nice post from Kate at Peace and Pekoe about manual labor and the mind.
It seems reasonable enough that there must be some real differences in cognitive development between the person who interacts with physical puzzles and products every day vs. those who only think and read and write and interact primarily with computers, pencil and paper. I see traits in my carpenter husband that seem organically connected with his trade, as though being a craftsman is a character trait like being introverted or optimistic, and I've learned to recognize some of these traits in other tradespeople as well – not that I find it easy to describe what exactly those traits are, without being guilty of over-generalization or romanticism. It's more a mode of being, thinking and doing, I think. In any case, I appreciate it and often envy it and I wonder sometimes whether anyone else has noticed this – this imprint one's work seems to make on one's soul – or whether I am alone in this.
Oh yeah, I've noticed it — I'm married to a process engineer, a very hands-on, problem-solving sort of person who loves his job and comes home dirty. I like to think I share a little bit of that mode of thinking, even though I always had a much more theoretical bent.
