_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. (shrink)

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)

One of the most effective ways of winning an argument is to show that your opponent has begged the question. If you are sufficiently skilful in asking him leading questions and have a good sense of timing you can usually succeed in stripping him to his bare principles, with no ascertainable means for their support. That such a tactic of debate should be so effective suggests that it is more than just a ploy. Indeed some philosophers would say that it (...) takes advantage of a characteristic which is inherent in the nature of argument itself, for all arguments must be question-begging. However, few would voice this conviction publicly—for fear of being accused of begging the question. (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.

In lieu of an abstract, here is a brief excerpt of the content:386 HISTORY OF PHILOSOPHY species of pragmatism, it could be said that there is indeed some justification for discovering analogies between the Heideggerian theory of truth and pragmatism. What is deplored by Vers6nyi is the loss of the concrete significance of tIeidegger's early theory of truth (as Vers~nyi characterizes it) and its replacement by a conception of truth which is paradoxical and ultimately fruitless for an understanding of the (...) world in which man finds himself. If Being is the groundless Ground, the Wholly Other, and if Being is truth, then truth is inaccesible to man. Truth, in Heidegger's later works, is beyond the finitude of self-reflective thought and can only be approached by means of a via negativa. This, however, is described as the "abandonment of reason." This critical analysis of Heidegger's thought is an interesting and challenging work which attempts a much needed appraisal of Heidegger's philosophical "voyage" from Being and Time to Gelassenheit. Some will be angered by the author's incisiveness; some will applaud his hostility to the dissolution of reason in mysticism; none can be indifferent to this valuable contribution to the study of Heidegger. GEORGEJ. STACK Long Island University A Short History o] Ethics. By Alasdair MacIntyre. (New York: The Macmillan Co., 1966. Pp. viii + 280 $4.95.) Professor MacIntyre's Short History o] Ethics turned out, to my surprise and pleasure, to be a quite different book from what I had expected. I had assumed from its title that it would consist of an exposition, analysis, and perhaps criticism of the theories of the standard great figures from the history of Western moral philosophy, stitched together by a thin thread of historical narrative. It does contain this standard material and the quality of exposition and analysis is very high. But there is much more to the book than that. For in it MacIntyre devotes a great deal of space to political and social philosophy, with discussions of figures like Machiavelli, Locke, Montesquieu, Rousseau, and Marx. Another subject that gets a good deal of attention is religion, including such writers as Luther, Calvin, and Kierkegaard. Even further afield, Professor MacIntyre surveys the beliefs and activities of certain social reformers---for example, the Diggers and Levellers in 17th century England--and the developments and changes in the moral attitudes and relationships of people in certain societies--for example, in ancient Greece. The result is a book that is very rich and varied in content, fascinating to read, and informative. Anyone, student or teacher, who is interested in technical ethics would be well advised to study it. Maclntyre has reasons for giving his book the wide scope it has. For he believes that ethics is a broad subject, concerned with the whole range of man's activities as a practical being. He rejects the notion currently popular that ethics should be a second-order undertaking, morally neutral in itself and limiting its activities to the logical analysis of first-order moral utterances (p. 3). The ethicist cannot, he believes, divorce himself from the social setting in which he lives, taking up a neutral position above the fray, because the very concepts he uses in his thinking and writing are "embodied in and are partially constitutive of forms of social life" (p. 1). The moral philosopher, in other words, is and must be articulating a set of beliefs and ideals that arise out of the general social and historical setting of which he is a part. To understand and appreciate his theories, therefore, we must be conversant with the social organization, political structure, and religious faith of his society. For it is only within this broad context that the concepts that any given ethicist employs become intelligible. MacIntyre's view seems to have one very controversial implication, on which I should like to comment. If the concepts employed by the ethicist are embodied in a given form of social life, then no ethical theory can transcend its historical setting, hence the question, Is a given ethical theory true or false? cannot legitimately be asked. The result is historical BOOK REVIEWS 387 relativism. MacIntyre recognizes this implication and has a good deal to... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:205 TIME AND THE IDEA OF TIME Hume entitled Part II of Book I of the Treatise "Of the Ideas of Space and Time." Students of this most obscure Part of the Book are aware, however, that he spends little time in it on time. The main reason for his concentration on space. is polemical. In Part II his primary object is to exhibit the contradictions and absurdities implicit (...) in the science of his day with its postulation of empty space and of the mathematics with its notion of infinite divisibility, and then to show how these difficulties can be overcome by the adoption and implementation of the theory of ideas he had developed in Part I. As a result, with the exception of a discussion that occupies approximately three pages in Section III, most of his references to time in Part II are little more than brief appendages tacked on to his arguments concerning space. Hume commentators have generally taken their cue from him. Although the literature contains substantial analyses of his views about space, very little can be found on the subject of time. In this paper, I shall attempt to add something to that slim literature. As its title indicates, this paper will be concerned with two subjects, time and the idea of time. Hume accepts the ordinary distinction between thé two. Time and our idea of time are separate realities, the former being a part of the world independent of us and the latter being a part of the content of our consciousness. I shall observe this distinction, beginning with an account of what Hume means by time and following that with an explanation of his theory of the origin and nature of the idea of time. After finishing these two expository sections I shall devote 206 the remainder of the paper to a critical examination of Hume's views on both subjects, ending with a suggestion about a possible alternative route he might have followed in his argument about time and the idea of time in Part II. A final preliminary point: Although Hume devotes most of his attention to space in Part II, he makes it clear that, because space and time (as well as our ideas of them) are analogous to each other in certain vital respects, his views concerning the former can easily be transferred and applied to the latter. 1. Time Hume states or implies several things about the nature of time in Part II. (1)He equates time with duration, treating the two terms as equivalent throughout his discussion. (2)Time is an objective reality, or aspect of the external world. This interpretation may be questioned because Hume never asserts an objectivistic view of time unequivocally and in certain passages writes in a way that could be interpreted as implying that time is a characteristic of our conscious experience. "As 'tis from the disposition of visible and tangible objects we receive the idea of space, so from the succession of ideas and impressions we form the idea of time..." (T 35). But later he writes: "...time is nothing but the manner, in which some real objects exist..." (T 64). Also, in the titles of his first two sections he makes a clear distinction, labelling Section I "Of the infinite divisibility of our ideas of space and time" and Section II "Of the infinite divisibility of space and time." Since, in Section II, it is apparent that he is talking about space as a part 207 of the external world, the natural inference is that he is talking about time in the same way, as, for example, when he writes, "The infinite divisibility of space implies that of time, as is evident from the nature of motion" (T 31). (3)Time is not infinitely divisible but is made up of parts Hume calls 'moments' (T 31). These moments are the 'building blocks' of time and are ultimate and indivisible. They are analogous to the ultimate, indivisible parts of space, which Hume labels 'mathematical points' (T 40). (4)The moments of time are not co-existent but successive. In this respect time differs from space. "'Tis also evident, that these parts [of... (shrink)

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 lieu of an abstract, here is a brief excerpt of the content:192 HUME'S REFUTATION OF — WOLLASTON? Recently while rereading Book III of Hume's Treatise I was struck by an anomaly in the text that I had never noticed before. It consists in the juxtaposition of two arguments Hume offers regarding the source of the moral qualities of our actions. At first I dismissed Hume's arrangement of these arguments as being of little consequence — one of them appears in (...) a footnote — but the more I thought about the juxtaposition the more it intrigued and puzzled me. Expecting that it must have been noted by other readers I checked through the literature to find some discussion of it. Since after a long search I have failed to uncover anything, and believing the point, which relates to Hume's central view concerning morality, to be of some interest, I have decided to write this brief paper. Two passages from § 1, entitled "Moral Distinctions not deriv'd from Reason," of Part I, Book III, are involved. Hume begins the section by arguing that, because of the limited scope of its capacities, reason cannot distinguish between right and wrong or, as he puts it, between virtue and vice, and therefore that it is a mistake to speak of actions as being reasonable or unreasonable. Since Hume's views on this question are well-known and since they are not directly relevant to the point of my paper, I shall not pursue them further, but turn directly to the issue at hand. After having stated his argument at the beginning of § 1 and reached the conclusion that "actions may be laudable or blameable, but they cannot be reasonable or unreasonable," Hume turns to answer an objection that might be made against him by a rationalist ethicist. He writes: 193 But perhaps it may be said, that tho' no will or action can be immediately contradictory to reason, yet we may find such a contradiction in some of the attendants of the action, that is, in its causes or effects (T 459). Pursuing this objection, Hume first considers the causes of our actions. He acknowledges that we can be led astray in what we do in two ways; by making mistakes of fact, first, about the nature of some object we desire (e.g., thinking some fruit delicious when it really is not) and, second, about the means we should employ to gain the object (e.g., attempting to pluck the fruit when it is beyond our reach). Although these errors cause us to act in ways that may be termed unreasonable in a "figurative and improper way of speaking" (T 459), they cannot be the source of any immorality in what we do because they are committed involuntarily and innocently. A person who falls into such errors and acts on them is "more to be lamented than blam'd" (T 459). To conclude his answer to the rationalistic objection he has raised, Hume turns next to the issue of whether the immorality of our actions can be explained in terms of the unreasonableness of any of their effects. In a memorable passage he denies that the fact that false judgments are the effects of our actions can be the source of immorality in what we do. As to those judgments which are the effects of our actions, and which, when false, give occasion to pronounce the actions contrary to truth and reason; we may observe, that our actions never cause any judgment, either true or false, in ourselves, and that 'tis only on others they have such an influence. 'Tis certain, that an action, on many occasions, may give rise to false conclusions in others; and that a 194 person, who thro' a window sees any lewd behaviour of mine with my neighbour's wife, may be so simple as to imagine she is certainly my own. In this respect my action resembles somewhat a lye or falshood; only with this difference, which is material, that I perform not the action with any intention of giving rise to a false judgment in another, but merely to satisfy my lust and passion. It causes, however, a mistake and false judgment by accident; and the falshood... (shrink)

The essay is an exposition and critical analysis of Peter Unger's book Ignorance: A Case for Scepticism (Oxford, 1975). 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)

As its title indicates, this book is concerned with two different fields of philosophy, ethics and epistemology. The bulk of the argument is devoted to epistemological questions, as these arise within the context of morality. Hence, the conclusions I reach could probably best be described as prolegomena to the elaboration of a theory of ethics. I have plans, which I hope will be realized in the next few years, of elaborating such a theory. I started work on Moral Knowledge in (...) the summer of 1958 with the help of a University Faculty Fellowship, for which I am most grateful. of the research for the book, as well as a good bit of its writing, Much was done in two libraries, The University Library, Berkeley, and the Bodleian Library, Oxford. Members of the staffs of both libraries, by their courtesy and helpfulness, lightened immeasurably the task of my research. lowe a special debt of gratitude to four people-to Mr. (shrink)

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.

To know is to believe but to believe is not necessarily to know. The latter, unfortunate fact gives rise quite naturally to the question: How can we distinguish between those beliefs that qualify as items of knowledge and those that do not? The standard reply given to this question by philosophers is that knowledge is justified belief. Although the reply sounds eminently reasonable it does not really answer the question. Rather than settling the issue it succeeds instead in stirring up (...) a host of philosophical problems of the most thorny and baffling kind. So difficult do these problems become that they have driven many philosophers to the skeptical conclusion that it is impossible to provide any justification for our beliefs at all. My main object in this paper will be to pursue what seems to me to be the most important and difficult of these problems and to examine some of the recent solutions that philosophers have offered for it. Before beginning this task, however, it might be well to clarify the notion of knowledge a bit more fully. Just what qualifies a belief as a justified belief and thus as an item of knowledge?

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)
