The author reviews the Confucian tradition through the two concepts, religion and humanities. Chinese scholars always adopt Zongjiao and Renwen from the ancient Chinese documents as the Chinese translation of religion and humanities. In respect of their own contexts of culture, the Chinese words and the English words share some similarities in meaning, but also have some vital differences. This book covers the major phases of the development of Confucianism, which have a wide historical span from the Pre-Qin period to the contemporary era with a focus on Confucianism in Song and Ming dynasties. Relevant ideas of modern Western disciplines such as philosophy of religion, religious studies and theology are employed by the author as references, not criteria, to illuminate key ideas in Confucian tradition and highlight the features of Confucianism as a religious or spiritual humanism. In some chapters, the author compares the eastern thinkers and theories with those western ones.
