An Introduction to Philosophy | Page 9

philosopher is the man to whom is committed what is left when we have taken away what has been definitely established or is undergoing investigation according to approved scientific methods. He is Lord of the Uncleared Ground, and may wander through it in his compassless, irresponsible way, never feeling that he is lost, for he has never had any definite bearings to lose.
Those who argue in this way support their case by pointing to the lack of a general consensus of opinion which obtains in many parts of the field which the philosopher regards as his own; and also by pointing out that, even within this field, there is a growing tendency on the part of certain sciences to separate themselves from philosophy and become independent. Thus the psychologist and the logician are sometimes very anxious to have it understood that they belong among the scientists and not among the philosophers.
Now, this answer to the question that we have raised undoubtedly contains some truth. As we have seen from the sketch contained in the preceding pages, the word philosophy was once a synonym for the whole sum of the sciences or what stood for such; gradually the several sciences have become independent and the field of the philosopher has been circumscribed. We must admit, moreover, that there is to be found in a number of the special sciences a body of accepted facts which is without its analogue in philosophy. In much of his work the philosopher certainly seems to be walking upon more uncertain ground than his neighbors; and if he is unaware of that fact, it must be either because he has not a very nice sense of what constitutes scientific evidence, or because he is carried away by his enthusiasm for some particular form of doctrine.
Nevertheless, it is just to maintain that the answer we are discussing is not a satisfactory one. For one thing, we find in it no indication of the reason why the particular group of disciplines with which the philosopher occupies himself has been left to him, when so many sciences have announced their independence. Why have not these, also, separated off and set up for themselves? Is it more difficult to work in these fields than in others? and, if so, what reason can be assigned for the fact?
Take psychology as an instance. How does it happen that the physicist calmly develops his doctrine without finding it necessary to make his bow to philosophy at all, while the psychologist is at pains to explain that his book is to treat psychology as "a natural science," and will avoid metaphysics as much as possible? For centuries men have been interested in the phenomena of the human mind. Can anything be more open to observation than what passes in a man's own consciousness? Why, then, should the science of psychology lag behind? and why these endless disputes as to whether it can really be treated as a "natural science" at all?
Again. May we assume that, because certain disciplines have taken a position of relative independence, therefore all the rest of the field will surely come to be divided up in the same way, and that there will be many special sciences, but no such thing as philosophy? It is hasty to assume this on no better evidence than that which has so far been presented. Before making up one's mind upon this point, one should take a careful look at the problems with which the philosopher occupies himself.
A complete answer to the questions raised above can only be given in the course of the book, where the main problems of philosophy are discussed, and the several philosophical sciences are taken up and examined. But I may say, in anticipation, as much as this:--
(1) Philosophy is reflective knowledge. What is meant by reflective knowledge will be explained at length in the next chapter.
(2) The sciences which are grouped together as philosophical are those in which we are forced back upon the problems of reflective thought, and cannot simply put them aside.
(3) The peculiar difficulties of reflective thought may account for the fact that these sciences are, more than others, a field in which we may expect to find disputes and differences of opinion.
(4) We need not be afraid that the whole field of human knowledge will come to be so divided up into special sciences that philosophy will disappear. The problems with which the philosopher occupies himself are real problems, which present themselves unavoidably to the thoughtful mind, and it is not convenient to divide these up among the several sciences. This will become clearer as we proceed.
