Belief in human selfishness, deeply rooted in Western thought from figures like Machiavelli to Hobbes, is challenged in "Humankind." Author Rutger Bregman argues that assuming people are good can be both realistic and revolutionary, countering the prevailing narrative that humans are inherently selfish. Bregman reframes famous studies and events to showcase human kindness, suggesting that by expecting the best in others, we can inspire positive change in society. This book offers a new perspective on human nature, advocating for a belief in human goodness as a basis for societal progress.
