That’s partly my title, anyway. I thoroughly enjoyed this very insightful and humorous lecture (72 minutes). Excellent. The summary posted at the YouTube video:
Twenty-first century depictions of love and marriage are shaped by a set of Romantic myths and misconceptions and with his trademark warmth and wit, Alain de Botton explores the complex landscape of a modern relationship, presenting a realistic case study for marriage and examining what it might mean to love, to be loved – and to stay in love.
If you want to listen to the lecture, as I did, e.g, in the car, convert the video at a site such as SaveTube.
How Romanticism Ruined Love, and corresponding video, which is a five-minute summary of the above lecture.
