An Introduction to Philosophy

by George Stuart Fullerton

We are conscious of the Unknowable,
The Unknowable lies behind the veil of phenomena,
Hence, we are conscious of what lies behind the veil of phenomena.

It is only the critical reader who notices that the Unknowable in the first line is the "raw material of consciousness," and the Unknowable in the second is something not in consciousness at all. The two senses of the word "light" are not more different from one another. Such apparent arguments abound, and it often requires much acuteness to be able to detect their fallacious character.

When we take into consideration the two points indicated above, we see that the logician is at every turn forced to reflect upon our knowledge as men do not ordinarily reflect. He is led to ask: What is truth? He cannot accept uncritically the assumptions which men make; and he must endeavor to become very clearly conscious of the real meaning and the whole meaning of statements expressed in words. Even in the simple logic with which we usually begin our studies, we learn to scrutinize statements in a reflective way; and when we go deeper, we are at once in contact with philosophical problems. It is evidently our task to attain to a clearer insight into the nature of our experience and the meaning of proof than is attainable by the unreflective.

Logic, then, is a reflective science, and it is not surprising that it has held its place as one of the philosophical sciences.

CHAPTER XVII

PSYCHOLOGY

69. PSYCHOLOGY AND PHILOSOPHY.—I think I have said enough in Chapter II (section 10) about what we mean when we speak of psychology as a natural science and as an independent discipline. Certainly there are many psychologists who would not care to be confused with the philosophers, and there are some that regard philosophy with suspicion.

Nevertheless, psychology is commonly regarded as belonging to the philosophical group. That this is the case can scarcely be thought surprising when we see how the psychologist himself speaks of the relation of his science to philosophy.

"I have kept," writes Professor James[1] in that delightful book which has become the common property of us all, "close to the point of view of natural science throughout the book. Every natural science assumes certain data uncritically, and declines to challenge the elements between which its own 'laws' obtain, and from which its own deductions are carried on. Psychology, the science of finite individual minds, assumes as its data (1) thoughts and feelings, and (2) a physical world in time and space with which they coexist, and which (3) they know. Of course, these data themselves are discussable; but the discussion of them (as of other elements) is called metaphysics and falls outside the province of this book."

This is an admirable statement of the scope of psychology as a natural science, and also of the relations of metaphysics to the sciences. But it would not be fair to Professor James to take this sentence alone, and to assume that, in his opinion, it is easy to separate psychology altogether from philosophy. "The reader," he tells us in the next paragraph, "will in vain seek for any closed system in the book. It is mainly a mass of descriptive details, running out into queries which only a metaphysics alive to the weight of her task can hope successfully to deal with." And in the opening sentence of the preface he informs us that some of his chapters are more "metaphysical" than is suitable for students going over the subject for the first time.
