PREFACE. This work is called the Critique of Practical Reason, not of the pure practical reason, although its parallelism with the speculative critique would seem to require the latter term. The reason of this appears sufficiently from the treatise itself. Its business is to show that there is pure practical reason, and for this purpose it criticizes the entire practical faculty of reason. If it... more...

INTRODUCTION The history of the evolution of life, incomplete as it yet is, already reveals to us how the intellect has been formed, by an uninterrupted progress, along a line which ascends through the vertebrate series up to man. It shows us in the faculty of understanding an appendage of the faculty of acting, a more and more precise, more and more complex and supple adaptation of the consciousness... more...

INTRODUCTION. OUR age is retrospective. It builds the sepulchres of the fathers. It writes biographies, histories, and criticism. The foregoing generations beheld God and nature face to face; we, through their eyes. Why should not we also enjoy an original relation to the universe? Why should not we have a poetry and philosophy of insight and not of tradition, and a religion by revelation to us, and... more...

ANTI-UTILITARIANISM. Having, by the heading of this essay, announced that it is intended to be partly controversial, I can scarcely begin better than by furnishing the reader with the means of judging whether I myself correctly apprehend the doctrine which I am about to criticise. If, then, I were myself an Utilitarian, and, for the sake either of vindicating my own belief, or of making converts of... more...

PROLOGUE What I am anxious to attempt in this anticipatory summary of the contents of this book is a simple estimate of its final conclusions, in such a form as shall eliminate all technical terms and reduce the matter to a plain statement, intelligible as far as such a thing can be made intelligible, to the apprehension of such persons as have not had the luck, or the ill-luck, of a plunge into the... more...

PERCY BYSSHE SHELLEY, AS A PHILOSOPHER AND REFORMER. A PAPER READ BEFORE THE NEW YORK LIBERAL CLUB, ON FRIDAY, AUGUST 6TH, 1875.  "Let us see the Truth, whatever that may be."—SHELLEY, 1822.   Mr. Vice-President and Members of the Liberal Club: "The Blood of the Martyr is the Seed of the Church." Persecution ever fails in accomplishing its desired ends, and as a rule lays the... more...

It may seem wonderful that language, which is the only method of conveying our conceptions, should, at the same time, be an hindrance to our advancement in philosophy; but the wonder ceases when we consider, that it is seldom studied as the vehicle of truth, but is too frequently esteemed for its own sake, independent of its connection with things. This observation is remarkably verified in the Greek... more...

THE PHILOSOPHY OF THE CONDITIONED. The reader of Plato’s Republic will readily recall to mind that wonderful passage at the end of the sixth book, in which the philosopher, under the image of geometrical lines, exhibits the various relations of the intelligible to the sensible world; especially his lofty aspirations with regard to “that second segment of the intelligible world, which reason of... more...

PREFACE This little work contains the chief ideas gathered together for a course of lectures on the theory and history of aesthetics given at Harvard College from 1892 to 1895. The only originality I can claim is that which may result from the attempt to put together the scattered commonplaces of criticism into a system, under the inspiration of a naturalistic psychology. I have studied sincerity... more...

CHAPTER I. INTRODUCTION. "Grau, theurer Freund, ist alle Theorie, Und grün des Lebens goldner Baum." (Faust.) There is a saying of Hegel's, frequently quoted, that "a great man condemns the world to the task of explaining him." The condemnation is a double one, and it generally falls heaviest on the great man himself, who has to submit to explanation; and, probably, the last... more...
