The author summarizes the ways psychoanalytical thinking conceptualized evil, seen as "what hurts" in the mind. She identifies three models: the first, called "hydrostatic" with its dynamic block versus dissolution; second: the "conflict", related to ideas of polarity and equi-librium; and last: minus K, Bion’s anti-thinking. The paper shows potential connections with the historical sequence and with changes in scientific and ethical paradigms. From the positiv-ism of the late ’800s to the experiences of two World Wars and the totalitarian regimes and tragedies that followed, there are connections with how we perceive "what hurts" in our and other’s minds.
