Stuart Sim starts with the proposition that pessimists simply have a more realistic world view. Tracing how pessimism has developed over time and exploring its multifaceted nature, he shows that many thinkers throughout history--including philosophers, theologians, authors, artists, and even scientists--have been pessimists at heart, challenging us to face up to the desperations that define human existence. Spanning cultures and moving across eras, he assembles a grand discourse of pessimism. Ultimately he offers the provocative argument that pessimism should be cultivated and vigorously defended as one of our most useful and ever-relevant dispositions.
