The 4 Keys to Happiness

In this book, Sam Harris challenges the traditional separation between scientific facts and human values. He argues that morality can be understood in terms of human and animal well-being, and that science can provide objective answers to moral questions. Harris contends that moral relativism is false and that science can tell us how we ought to live to achieve the greatest well-being. He uses his expertise in philosophy and neuroscience to make a case for a science of morality, emphasizing that moral values should be grounded in empirical facts about what causes people to flourish.

In this book, Jonathan Haidt draws on twenty-five years of research on moral psychology to explain why people's moral judgments are driven by intuition rather than reason. He introduces the Moral Foundations Theory, which posits that human morality is based on six foundations: care/harm, fairness/cheating, loyalty/betrayal, authority/subversion, sanctity/degradation, and liberty/oppression. Haidt argues that liberals tend to focus on the care/harm and fairness/cheating foundations, while conservatives draw on all six. The book also explores how morality binds and blinds people, leading to social cohesion but also to conflicts. Haidt aims to promote understanding and civility by highlighting the commonalities and differences in moral intuitions across political spectra.
