I. Guiding Thoughts on the Method of Presentation
We can hope that such an examination can yield results concerning the nature of human soul development, and the writer of this book believes that in exploring the philosophical views of the occident he has found such results. Four distinctly discernible epochs in the evolution of the philosophical struggle of mankind presented themselves to his view. He had to recognize the difference of these epochs as distinct as the difference of the species of a realm of nature. This observation led him to acknowledge in the realm of the history of man's philosophical development the existence of objective spiritual impulses following a definite law of evolution of their own, independent of the individual men in whom they are observed. The achievements of these men as philosophers thus appear as the manifestation of these impulses that direct the courses of events under the surface of external history. The conviction is then suggested that such results arise from the unprejudiced observation of the historical facts, much as a natural law rests on the observation of facts of nature. The author of this book believes that he has not been misled by preconceptions to present an arbitrary construction of the historical process, but that the facts force the acknowledgment of results of the kind indicated.
