Why should we believe in God without any evidence? How can there be meaning in life when death is final? Does a Godless universe imply moral relativism? With adherents including Einstein, Freud, Philip Pullman, and Frank Zappa, and often described as the thinking person's religion, Humanism aims to make sense of such questions by appealing to shared human values, rationality, and tolerance. This lively and provocative book is essential reading for atheists, agnostics, freethinkers, rationalists, sceptics, and believers alike. Peter Cave is a writer, presenter, and lecturer in philosophy at The Open University and City University, London.
