What is jealousy, actually? What motivates the feeling and why is it so easy to get whipped up into a frenzy of jealousy? It turns out that literature - specifically fiction - has given us a laboratory to explore the emotion. Sehgal gives examples from Proust to Sherlock Holmes, to show how envy and jealousy are not so different from a quest for knowledge.
It's a fascinating and thought-provoking talk (as all TED talks are), with great self-awareness and some humor. Ms. Sehgal clearly has a grasp of the breadth of fiction and is able to pull intelligent and specific examples out to illustrate her points.
One last thing that endears Sehgal to us: her website is subtitled incunabula. The astute Sherlockians among you will realize that Edgar W. Smith, BSI wrote The Incunabular Sherlock Holmes in 1958.
