James believed that philosophy was meant to articulate, and help answer, a single existential question, one which lent itself to the title of one of his most famous essays: "Is life worth living?" Through examination of an array of existentially loaded topics covered in his works-truth, God, evil, suffering, death, and the meaning of life-James concluded that it is up to us to make life worth living. He said that our beliefs, the truths that guide our lives, matter-their value and veracity turn on the way they play out practically for ourselves and our communities. For James, philosophy was about making life meaningful, and for some of us, liveable. This is the core of his "pragmatic maxim," that truth should be judged on the bases of its practical consequences. Kaag shows how James put this maxim into use in his philosophy and his life and how we can do so in our own. .
