When The Universe Next Door was first introduced more than twenty years ago, it set the standard for a clear, readable introduction to worldviews. In concise, easily understood prose, James W. Sire explained the basics of theism, deism, naturalism, nihilism, existentialism, Eastern monism and the new consciousness. Later editions have updated and expanded to include important sections on Marxism, secular humanism, New Age philosophy, and postmodernism. The Universe Next Door has been translated into many languages and has been used as a text at over one hundred colleges and universities in courses ranging from apologetics and world religions to history and English literature. This latest edition will continue to aid students, teachers and anyone who wants to understand the variety of worldviews that compete with Christianity.
