_Skepticism and Cognitivism_ addresses the fundamental question of epistemology: Is knowledge possible? It approaches this query with an evaluation of the skeptical tradition in Western philosophy, analyzing thinkers who have claimed that we can know nothing. After an introductory chapter lays out the central issues, chapter 2 focuses on the classical skeptics of the Academic and Pyrrhonistic schools and then on the skepticism of David Hume. Chapters 3 through 5 are devoted to contemporary defenders of skepticism—Keith Lehrer, Arne Næss, and (...) Peter Unger. In chapter 6, author Oliver A. Johnson dons the mantle of skeptic himself and develops and adds theories to the skeptical arsenal. He closes with an examination of the relationship between skepticism and cognitivism, reaching and defending conclusions on the nature and extent of possible human knowledge.

In his essay “Logical Empiricism”, in the anthology Twentieth Century Philosophy, Professor Feigl writes: “All forms of empiricism agree in repudiating the existence of synthetic a priori knowledge.” Schlick makes the same point even more forcibly: “The empiricism which I represent believes itself to be clear on the point that, as a matter of principle, all propositions are either synthetic a posteriori or tautologous; synthetic a priori propositions seem to it to be a logical impossibility.” The denial of synthetic a (...) prioris is a major thesis of the logical empiricist position, being found in the writings of most of the leaders of the movement. The reason for its importance is fairly clear. It provides a formula on which the empiricists can base their critique of traditional philosophy. To use Ayer's phrase, denial of the synthetic a priori results in “the elimination of metaphysics”. The philosophical tradition to which the empiricists are opposed and whose “metaphysics” they wish to eliminate can be called, somewhat loosely, rationalism. (shrink)
The paper is a combination of criticism and defense of ethical intuitionism, Meaning by this the view that we have insights about such matters that we can know to be true. Although the thesis is accepted that intuition is an authentic source of ethical knowledge, Many of the claims of intuitionists are subjected to critical scrutiny.

Brand Blanshard devotes a substantial part of his book Reason and Goodness to a discussion of ethical subjectivism. It need hardly be said that his discussion is critical; Blanshard is a thoroughgoing ethical objectivist. Nevertheless, although he rejects subjectivism as an ethical theory, he is fully appreciative of the importance of subjective elements—emotions, feelings, attitudes—in our ordinary, practical moral activities. He recognizes these, along with reason, to be essential parts of the good life for human beings.
In my various introductions, in addition to offering a humanistic setting for the selections presented, I have endeavored to provide an intellectual and historical context as well, and survey of the main problems with which they are concerned plus a review of the alternative solutions to these problems that philosophers have offered.
Finding descriptive titles for books devoted to central issues in philosophy can often become a problem; it is very difficult to be original. Thus the title that I have given to this book is far from novel, having already been used several times by other authors. Nevertheless, I think that I can fairly claim to have employed it in a way that no one else has done before. Concerning my subtitle, some comments are in order. I have added it to (...) emphasize my views regarding the nature and scope of epistemology. In particular, I wish to draw attention to the fact that I conceive its subject matter quite broadly. Rather than equating it, as is often done, with "theory of knowledge," I believe that epistemology should concern itself with the philosophical investigation of human belief in general. The two categories of human belief of most importance to the epistemologist are knowledge and what I shall call in the book "reasonable belief. " In my opinion a complete epistemology must take account of both, attempting to resolve the problems that are peculiar to each. For reasons that I give in the book I believe that knowledge and its problems must be the first concern of the epistemologist. Only after he has developed a satisfactory theory of knowledge can he tum, with any hope of success, to the formu lation of a theory of reasonable belief. (shrink)
The essay is an exposition and critical analysis of Peter Unger's book Ignorance: A Case for Scepticism. In the introductory chapter my main object, in addition to defining terms, is to distinguish the two forms of scepticism Unger defends in Ignorance, which he calls, respectively, scepticism about knowledge and scepticism about rationality. Chapter II is devoted to an exposition, analysis, and evaluation of the latter and Chapter III of the former. In Chapter IV I consider a second-order argument that informs (...) Unger's case throughout the book, his "ancestor language" hypothesis. In the final chapter I assess his scepticism as a whole and attempt to develop some of its implications concerning both the possibility and actuality of knowledge. (shrink)
