The agony of love is a classic trope of romantic literature and popular journalism. The suffering caused by failures in our personal lives seems timeless. But the sociologist, Eva Illouz, argues that the nature of romantic suffering has changed radically in the modern era. Her book 'Why Love Hurts' argues that the individual misery of the 'broken hearted' should be subjected to scrutiny by social scientists. Failures in our private lives are shaped by social forces much larger than ourselves; they can't be explained by our individual psyches and histories alone. Stephen Frosh, Professor of Psychosocial studies, also joins the discussion. Laurie Taylor puts love under the sociological microscope.
