It’s not the discipline that makes it part of liberal education, it’s the way you approach it. A liberal arts school is not about having lots of classics professors and no economics professors. It’s about teaching the subject in such a way that it broadens students’ perspectives rather than closing them down into specialization. At Wesleyan, for example, I’ve been trying to bring in engineering as a way of thinking and problem solving. Not just as a trade school. I’ve met with some real resistance, but you can teach engineering as part of a liberal education, just as you can teach it as part of technical training.
