In the trades, a weld either holds or it doesn't — there's no polite fiction about it. Aristotle called this kind of knowledge 'techne': the understanding that lives in your hands and eyes as much as your mind, built through repetition until judgment becomes instinct. But he made a crucial distinction: techne isn't just skill, it's the capacity to understand *why* something works, which is what separates a craftsman who can replicate from one who can solve. When you're fitting pipe in a confined space or reading heat color on a bead, you're not just executing procedure — you're exercising a form of intelligence that Aristotle considered fundamental to human flourishing, one that university philosophy departments spent centuries undervaluing.

Is there a technique you perform correctly every time but couldn't fully explain to someone else — and what would it take to close that gap?
