Life instinct, in Freudian theory (4)

I believe the answer is:

eros

(Other definitions for eros that I've seen before include "Arrow shooter" , "Asteroid - Greek god of love" , "Greek love-god" , "Greek god of love - see statue in Piccadilly" , "God of love - example of 1 down" .)

I've seen this clue in The Wall Street Journal.
