Professor Breyer argues for the essential role that luck plays in our lives, considering how luck affects our views of happiness, success, justice, responsiblity, and even knowledge. Using fascinating stories (some fictional, others real life), Breyer explores what philosphers and pscyhologists, both past and present, have said about luck, while making the case that thinking about luck should change how we see the world. Along the way, you will consider fascinating cases of so-called moral luck that just might convince you to reconsider your most basic moral judgments. And you will even explore the science of luck (yes, there is such a thing), as well as epistemic luck—a kind of luck that threatens to undermine knowledge itself.
