And what does this mean for the habits of mind we cultivate? I return often to the ideas of Jack Miles in this essay—also about generalists and specialists, with a key useful heuristic: that specialists tend to embody all the disposition of farmers, while generalists tend to embody the virtues of hunters. Both are necessary, and both need each other. The careful tending to a field whose needs are more or less known, protected, and nurtured further, on the one hand. And the more landscape-crossing, round-the-next-bend pursuit of the not yet known and its promised nourishment, on the other.

I want students to try out and value both operative modes, no matter where their own career paths take them. Knowing that others are also asking valuable questions in different disciplinary ways ideally breeds humility: a sense that what one has to offer could be enriched when conjoined in conversation with others whose expertise may not be immediately legible from within a silo.

And not just humility: I want students in engineering to know that their practices can be both private and public, that their status as citizens can be catalyzed through making things.
