What's good about an individual human life can't be boiled down to any single value. Pluralist theories are more plausible postulating a variety of relevant values, including well being and justice. One interesting aspect is that for humans, and no other creature, what's typically negative can become positive. Being afraid in a safe environment can be a source of joy - just like anger and sadness.
We go to movies that make us cry, or scream, or gag. We poke at sores, eat spicy foods, immerse ourselves in hot baths, run marathons. Some of us even seek out pain and humiliation in sexual role-play. Why do we so often seek out physical pain and emotional turmoil? Where do these seemingly perverse appetites come from? In his latest book, The Sweet Spot: The Pleasures of Suffering and the Search for Meaning, Bloom aims to understand how people find meaning in their lives, and, moreover, to explore what he calls, “the sweet spot” — the proper balance between pleasure and suffering. As one of the world’s leading psychologists, drawing on groundbreaking findings from psychology and brain science, Bloom shows how the right kind of suffering sets the stage for enhanced pleasure.
