With over a quarter million copies in print in three editions, The Universe Next Door has established itself as the premier textbook on worldviews. In clear, readable prose, James W. Sire explains the basics of Christian theism, deism, naturalism, nihilism, existentialism, Eastern pantheistic monism, New Age philosophy and postmodernism. In an increasingly pluralistic academic environment, the ability to understand and evaluate various worldviews is vitally important.
