Cliff of Better Than Food Book Reviews (YouTube channel) reviews Seneca's "On the Shortness of Life." I found the review particularly interesting and it was great to hear Cliff reflect on how the essay has impacted how he sees time, aging, and life in general.
I used the same essay in a first-year writing seminar (required of all freshmen at Moravian) that I opted to title, "What is the Good Life?" The central question was, of course, "What makes a life, a good life?" We used the Hadas Seneca book but the translation was dated enough that in the future when I teach the course I'd probably try to find another. Seneca is, however, particularly compelling for such a seminar and the students enjoyed him immensely.
We also covered Socrates, Plato, Aristotle, Epicurus, Epictetus, Montaigne, Schopenhauer, Nietzsche, and a few others.
While I'm thinking of it, several years ago when this blog first started (wow...it's been nearly seven years!) I wrote THIS piece on ancient ethics.
