To Martin a liberal education meant “the kind of education which setsthe mind free from the servitude of the crowd and from vulgar self-interests.”
He didn't have the framework to describe it in behavioral economic terms, but Everett Dean Martin's idea of a liberal education in 1926 was to encourage the use of Kahneman & Tversky's system two over system one. It takes more work, but system two thinking can generally beat out system one gut reactions for building a better life.
