According to the Preface: "The purpose of the book will in part account for those shortcomings that immediately reveal themselves to the eye of the scholar. ... I have sought to introduce the general stand-point and problem of philosophy through its implication in practical life, poetry, religion, and science. But in so doing it has been necessary for me to deal shortly with topics of great independent importance, and so risk the disfavor of those better skilled in these several matters. This is evidently true of the chapter which deals with natural science. But the problem which I there faced differed radically from those of the foregoing chapters, and the method of treatment is correspondingly different. In the case of natural science one has to deal with a body of knowledge which is frequently regarded as the only knowledge. To write a chapter about science from a philosophical stand-point is, in the present state of opinion, to undertake a polemic against exclusive naturalism, an attitude which is itself philosophical, and as such is well known in the history of philosophy as positivism or agnosticism. I have avoided the polemical spirit and method so far as possible, but have, nevertheless, here taken sides against a definite philosophical position. This chapter, together with the Conclusion, is therefore an exception to the purely introductory and expository representation which I have, on the whole, sought to give."
