Thomas Aquinas, who's following Aristotle), argued you couldn't have any of the cardinal virtues without having them all - but also (with Aquinas going beyond Aristotle) asserted that you need to receive the theological virtues (faith, hope and charity/love) to really have the cardinal virtues.I'd forgotten how I love this material - it's my first time teaching it in five years. By golly, I find I actually think it's true. (You can even be a religious naturalist about the theological virtues, I think, at least up to a point: you can't make yourself have hope or faith or love, but they evidently happen. Something makes them possible, something mysterious, bigger than us but of which we are a part.)
