Abstract
Religion is a social ideology. Today the study of the history of the development of a religion as an ideology not only has a general significance but also a particular significance. It is possible for us to discern, from a plethora of evidence in places outside of China, that while scientific technology may be progressing and developing rapidly, progress has not brought about a decline in religious ideology but has indeed strengthened people's pursuit of religion. From our own domestic conditions, too, we can see that for all sorts of reasons, there is a growing trend among people to adhere to one religion or another. Such a phenomenon, therefore, suggests a number of theoretical questions related to religion that ought to be studied seriously, such as: What is the essence of religion? "Is it a psychological characteristic of human beings to need some kind of religious faith? Axe religion and religious belief one and the same thing? Can religious faith be of benefit to social life? Are religion and science mutually contradictory? Are they mutually supplementary? Can religion be modernized? Naturally, these problems do not fall within the scope of this essay. Nonetheless, there are, I believe, related questions that ought to be given consideration by those who write the history of religions, such as why we study the history of religions at all, whether a good study in the history of religions ought to have a strong sense of the times, and whether or not it is sufficient to bring the people who have read such a study to consider seriously and earnestly the religious questions that exist in the contemporary world
