“The pragmatist regards any theory as a mere mathematical machine for generating numbers which he then compares with experiment. A pragmatist is concerned with results, not reality. The pragmatist refuses on principle to speculate about deep reality, such a concept being meaningless from his point of view. Pragmatism is an intelectually safe but ultimately sterile philosophy.”

“Indeed, once Kant had discovered the Humean problem of skepticism about the universality and necessity of first principles, he generalized it not only to the first principles of “speculative philosophy,” that is, theoretical cognition, but also to the first principle of practical philosophy, the fundamental principle of morality. Thus, from a methodological point of view, Kant’s project in philosophy became that of undermining both Humean and Pyrrhonian skepticism in both theoretical and practical philosophy, and, much more incidentally, along the way refuting Cartesian skepticism about external objects as a nagging but by no means central problem in theoretical philosophy.”

“The formalists neglected the content altogether and made mathematics meaningless, the logicians neglected the form and made mathematics consist of any true generalizations; only by taking account of both sides and regarding it as composed of tautologous generalizations can we obtain an adequate theory.”

“No such luck. " He smiles. "For better or for worse, I don't have that kind of power. If I sound like I'm always predicting ominous things, it's because I'm a pragmatist. I use deductive reasoning to generalize, and I suppose this sometimes winds up sounding like unlucky prophecies. You know why? Because reality's just the accumulation of ominous prophecies come to life. All you have to do is open a newspaper on any given day and weigh the good news versus the bad news, and you'll see what I mean.”

“In war, theory is all right so far as general principles are concerned; but in reducing general principles to practice there will always be danger. Theory and practice are the axis about which the sphere of accomplishment revolves.”

“Generally speaking there is no irreducible taste or inclination. They all represent a certain appropriative choice of being. It is up to existential psychoanalysis to compare and classify them. Ontology abandons us here; it has merely enabled us to determine the ultimate ends of human reality, its fundamental possibilities, and the value which haunts it.”

“The 'physical' does not mean any particular kind of reality, but a particular kind of denoting reality, namely a system of concepts in the natural sciences which is necessary for the cognition of reality. 'The physical' should not be interpreted wrongly as an attribute of one part of reality, but not of the other; it is rather a word denoting a kind of conceptual construction, as, e. g., the markers 'geographical' or 'mathematical', which denote not any distinct properties of real things, but always merely a manner of presenting them by means of ideas.”

“How can it be that mathematics, being after all a product of human thought which is independent of experience, is so admirably appropriate to the objects of reality? Is human reason, then, without experience, merely by taking thought, able to fathom the properties of real things?”

“One of Collingwood's earliest attempts to define the aesthetic essence of art. His aim, he writes in the preface, is to state a general conception of art and develop its consequences. His conception is one already familiar through the writings of others -- "that art is as bottom neither more nor less than imagination" -- but from his observation he goes on to outline the various distinctions between subordinate conceptions of art, and to attempt to demonstrate their place in the general conception, and the place of both in life. He urges that the meaningfulness of art cannot be torn from the imaginative setting in which it is embedded, and that we must attempt to explain the process by which an artist reaches a particular point of view on reality.”
