The phenomenology of religion concerns the experiential aspect of religion, describing religious phenomena in terms consistent with the orientation of worshippers. It views religion as made up of different components, and studies these components across religious traditions in order to gain some understanding of them. A different approach is that of typological or classifying phenomenology, which seeks to describe and explain religion in general by analyzing the many diverse 'phenomena' of religions, such as rituals, holy places, narratives, religious roles, and the many other modes of religious expression. In this respect, the phenomenology of religion takes the generalizing role that linguistics has over philologies or that anthropology has in relation the specific ethnographies: where the history of religions produces insights into specific religious traditions, the phenomenology of religion becomes the general scholarly (or scientific) enterprise that explains and interprets religious phenomena in general. Chantepie de la Saussaye The first explicit use of the phrase "phenomenology of religion" occurs in the Lehrbuch der Religionsgeschichte (Handbook of the History of Religions), written by Pierre Daniël Chantepie de la Saussaye in 1887, wherein he articulates the task of the science of religion and gives an "Outline of the phenomenology of religion". Employing the terminology of Georg Wilhelm Friedrich Hegel, Chantepie divides his science of religion into two areas of investigation, essence and manifestations, which are approached through investigations in philosophy and history, respectively. However, Chantepie's phenomenology "belongs neither to the history nor the philosophy of religion as Hegel envisioned them". For Chantepie, it is the task of phenomenology to prepare historical data for philosophical analysis through "a collection, a grouping, an arrangement, and a classifying of the principal groups of religious conceptions". This sense of phenomenology as a grouping of manifestations is similar to the conception of phenomenology articulated by Robison and the British; however, insofar as Chantepie conceives of phenomenology as a preparation for the philosophical elucidation of essences, his phenomenology is not completely opposed to that of Hegel. Kristensen Chantepie's Lehrbuch was highly influential, and many researchers began similar efforts after its publication and its subsequent translation into English and French. One such researcher was William Brede Kristensen. In 1901, Kristensen was appointed the first professorship relating to the phenomenology of religion at the University of Leiden. Some of the material from Kristensen's lectures on the phenomenology of religion was edited posthumously, and the English translation was published in 1960 as
