An Introduction to Philosophy Part 30

Professor Aikins writes: "Thus, in so far as logic tries to make us reason correctly by giving us correct conceptions of things and the way in which their relations involve each other, it is a kind of simple metaphysics studied for a practical end."

Professor Creighton says, "Although in treating the syllogistic logic I have followed to a large extent the ordinary mode of presentation, I have both here, and when dealing with the inductive methods, endeavored to interpret the traditional doctrines in a philosophical way, and to prepare for the theoretical discussions of the third part of the book."

John Stuart Mill tried not to be metaphysical; but let the reader examine, say, his third chapter, "Of the Things denoted by Names," or look over Book VI, in his "System of Logic."

Professor Sigwart's great work, "Logik" (Freiburg, 2d edition, Volume I, 1889, Volume II, 1893), may almost be called a philosophy of logic.

CHAPTER XVII, section 69. Compare with Professor James's account of the scope of psychology the following from Professor Baldwin: "The question of the relation of psychology to metaphysics, over which a fierce warfare has been waged in recent years, is now fairly settled by the adjustment of mutual claims. . . . The terms of the adjustment of which I speak are briefly these: on the one hand, empirical investigation must precede rational interpretation, and this empirical investigation must be absolutely unhampered by fetters of dogmatism and preconception; on the other hand, rational interpretation must be equally free in its own province, since progress from the individual to the general, from the detached fact to its universal meaning, can be secured only by the judicious use of hypotheses, both metaphysical and speculative. Starting from the empirical we run out at every step into the metempirical." "Handbook of Psychology," Preface, pp. iii and iv.

CHAPTER XVIII, section 71. The teacher might very profitably take extracts from the two chapters of Whewell's "Elements of Morality"

referred to in the text, and read them with the cla.s.s. It is significant of the weakness of Whewell's position that he can give us advice as long as we do not need it, but, when we come to the cross-roads, he is compelled to leave the matter to the individual conscience, and gives us no hint of a general principle that may guide us.

Section 72. Wundt, in his volume "The Facts of the Moral Life" (N.Y., 1897), tries to develop an empirical science of ethics independent of metaphysics; see the Preface.

Compare with this: Martineau's "Types of Ethical Theory" (London, 1885), Preface; T. H. Green's "Prolegomena to Ethics," Introduction; Muirhead's "The Elements of Ethics" (N.Y., 1892); Mackenzie's "A Manual of Ethics" (London, 1893); Jodl's "Gesduchte der Ethik" (Stuttgart, 1882), Preface. I give but a few references, but they will serve to ill.u.s.trate how close, in the opinion of ethical writers, is the relation between ethics and philosophy.

CHAPTER XIX, section 74. The student who turns over the pages of several works on metaphysics may be misled by a certain superficial similarity that is apt to obtain among them. One sees the field mapped out into Ontology (the science of Being or Reality), Rational Cosmology, and Rational Psychology. These t.i.tles are mediaeval landmarks which have been left standing. I may as well warn the reader that two men who discourse of Ontology may not be talking about the same thing at all. Bear in mind what was said in section 57 of the different ways of conceiving the "One Substance"; and bear in mind also what was said in Chapter V of the proper meaning of the word "reality."

I have discarded the above t.i.tles in my "System of Metaphysics,"

because I think it is better and less misleading to use plain and unambiguous language.

Section 75. See the note to Chapter XVI.

CHAPTER XX, sections 76-77. One can get an idea of the problems with which the philosophy of religion has to deal by turning to my "System of Metaphysics" and reading the two chapters ent.i.tled "Of G.o.d," at the close of the book. It would be interesting to read and criticise in cla.s.s some of the theistic arguments that philosophers have brought forward. Quotations and references are given in Chapter x.x.xIV.

CHAPTER XXI, sections 78-79. What is said of the science of logic, in Chapter XVI, has, of course, a bearing upon these sections. I suggest that the student examine a few chapters of "The Grammar of Science"; the book is very readable.

CHAPTER XXII, sections 80-82. The reader will find in lectures I and II in Sir William Hamilton's "Lectures on Metaphysics" a discussion of the utility of philosophy. It has a pleasant, old-fas.h.i.+oned flavor, and contains some good thoughts. What is said in Chapters XVI-XXI of the present volume has a good deal of bearing upon the subject. See especially what is said in the chapters on logic, ethics, and the philosophy of religion.

CHAPTER XXIII, sections 83-87. There is a rather brief but good and thoughtful discussion of the importance of historical study to the comprehension of philosophical doctrines in Falckenberg's "History of Modern Philosophy" (English translation, N.Y., 1893); see the Introduction.

We have a good ill.u.s.tration of the fact that there may be parallel streams of philosophic thought (section 87) when we turn to the Stoics and the Epicureans. Zeno and Epicurus were contemporaries, but they were men of very dissimilar character, and the schools they founded differed widely in spirit. Zeno went back for his view of the physical world to Herac.l.i.tus, and for his ethics to the Cynics. Epicurus borrowed his fundamental thoughts from Democritus.

On the other hand, philosophers may sometimes be regarded as links in the one chain. Witness the series of German thinkers: Kant, Fichte, Sch.e.l.ling, Hegel, Schopenhauer; or the series of British thinkers: Locke, Berkeley, Hume, Mill. Herbert Spencer represents a confluence of the streams. The spirit of his doctrine is predominantly British; but he got his "Unknowable" from Kant, through Hamilton and Mansel.

At any point in a given stream there may be a division. Thus, Kant was awakened to his creative effort by Hume. But Mill is also the successor of Hume, and more truly the successor, for he carries on the traditional way of approaching philosophical problems, while Kant rebels against it, and heads a new line.

CHAPTER XXIV, sections 88-93. I hardly think it is necessary for me to comment upon this chapter. The recommendations amount to this: that a man should be fair-minded and reasonable, free from partisans.h.i.+p, cautious, and able to suspend judgment where the evidence is not clear; also that where the light of reason does not seem to him to s.h.i.+ne brightly and to illumine his path as he could wish, he should be influenced in his actions by the reflection that he has his place in the social order, and must meet the obligations laid upon him by this fact. When the pragmatist emphasizes the necessity of accepting ideals and living by them, he is doing us a service. But we must see to it that he does not lead us into making arbitrary decisions and feeling that we are released from the duty of seeking for evidence. Read together sections 64, 91, and 93.
