This book is about the quest for order in a perplexing world. Ideas to Save Your Life follows Michael McGirr's much-admired Books that Saved My Life (2018). This time, instead of sharing his love of literature, McGirr shares his love of philosophy, focusing on the works of twenty-plus eminent thinkers across history. The book goes back to Pythagoras and comes forward to the contemporary Australian Frank Jackson; back to Mungo Woman and forward to Martha Nussbaum, by way of Simone Weil and Iris Murdoch. It is animated by two related questions- from where do we draw a sense of life's purpose? And how can philosophy make life better? It ranges widely across subjects-from solitude to community, language to order, experience to ecstasy, the idea of good to that of a good idea. McGirr's approach is warm and inviting. Drawing on his many years of teaching philosophy to teenagers, he shares stories from his life and the lives of others. Ideas to Save Your Life is often funny, but it is always serious about the task of philosophy. It makes the impenetrable accessible, the indescribable palpable, and invites you to change how you see the world.
