"The Secular City" is a book written by theologian Harvey Cox in 1965. It explores the shift from traditional religious values to a more secular worldview in urban environments. Cox argues that modern cities are places where diverse beliefs coexist, leading to new forms of spirituality and community. The book discusses the implications of secularization for society, emphasizing the need for dialogue between faith and reason. Cox suggests that urban life can foster creativity and social justice, encouraging individuals to engage with the world around them without relying solely on religious frameworks.
