I present two measures of information for both consistentand inconsistent sets of sentences in a finite language ofpropositional logic. The measures of information are based onmeasures of inconsistency developed in Knight (2002).Relative information measures are then provided corresponding to thetwo information measures.
I provide a method of measuring the inconsistency of a set of sentences from 1-consistency, corresponding to complete consistency, to 0-consistency, corresponding to the explicit presence of a contradiction. Using this notion to analyze the lottery paradox, one can see that the set of sentences capturing the paradox has a high degree of consistency (assuming, of course, a sufficiently large lottery). The measure of consistency, however, is not limited to paradoxes. I also provide results for general sets of sentences.
In this paper we present a probabilistic notion of entailment for finite sets of premises, which has classical entailment as a special case, and show that it is well defined; i.e., that the problem of whether a sentence is entailed by a set of premises is computable. Further we present a natural deductive system and prove that it is the strongest deductive system possible without referring to probabilities.
Aristotle is the most influential philosopher of practice, and Knight's new book explores the continuing importance of Aristotelian philosophy. First, it examines the theoretical bases of what Aristotle said about ethical, political and productive activity. It then traces ideas of practice through such figures as St Paul, Luther, Hegel, Heidegger and recent Aristotelian philosophers, and evaluates Alasdair MacIntyre's contribution. Knight argues that, whereas Aristotle's own thought legitimated oppression, MacIntyre's revision of Aristotelianism separates ethical excellence from social elitism and (...) justifies resistance. With MacIntyre, Aristotelianism becomes revolutionary. MacIntyre's case for the Thomistic Aristotelian tradition originates in his attempt to elaborate a Marxist ethics informed by analytic philosophy. He analyses social practices in teleological terms, opposing them to capitalist institutions and arguing for the cooperative defence of our moral agency. In condensing these ideas, Knight advances a theoretical argument for the reformation of Aristotelianism and an ethical argument for social change. (shrink)
The essays in this collection explore the implications of Alasdair MacIntyre's critique of liberalism, capitalism, and the modern state, his early Marxism, and the complex influences of Marxist ideas on his thought. A central idea is that MacIntyre's political and social theory is a form of revolutionary--not reactionary--Aristotelianism. The contributors aim, in varying degrees, both to engage with the theoretical issues of MacIntyre's critique and to extend and deepen his insights. The book features a new introductory essay by MacIntyre, "How (...) Aristotelianism Can Become Revolutionary," and ends with an essay in which MacIntyre comments on the other authors' contributions. It also includes Kelvin Knight's 1996 essay, "Revolutionary Aristotelianism," which first challenged conservative appropriations of MacIntyre's critique of liberalism by reinterpreting his Aristotelianism through the lens of his earlier engagement with Marx. "This is an excellent collection. Its particular strength is its sustained focus on Alasdair MacIntyre's political thought, in particular MacIntyre's complicated relation and indebtedness to Marxism. In their introduction, the co-editors say that the reception of MacIntyre within political philosophy has largely been reductive and one-sided, namely, that he is simply viewed as a conservative communitarian. In focusing on MacIntyre's radical heritage, this volume helps correct that simplistic misperception. --_Keith Breen, Queen's University Belfast_. (shrink)

Most of us take it for granted that we are free agents: that we can sometimes act so as to shape our own lives and those of others, that we have choices about how to do so and that we are responsible for what we do. But are we really justified in believing this? For centuries philosophers have argued about whether free will and moral responsibility are compatible with determinism or natural causation, and they seem no closer to agreeing about (...) it now than at any time in the past. Many contemporary philosophers have come to the conclusion that the intractability of the old argument about free will and determinism is caused by deep rooted illusions and inconsistencies in our unreflective attitudes about moral responsibility and freedom to act. Kevin Magill challenges this view and argues that the philosophical stalemate about free will has arisen through lack of attention to the content of the experiences that shape our understanding of free will and agency and through a mistaken belief that the concept of moral responsibility requires a moral and metaphysical justification. The book sets out an original account of the various ways we experience choosing, deciding and acting, which reconciles the apparently opposing intuitions that have fuelled the traditional dispute.

Li Da (1890–1966) was one of China’s most important Marxist intellectuals and a founding member of the Chinese Communist Party. He played a major role in the introduction of Marxist philosophy and theory to China and in its dissemination among Chinese revolutionaries. His works are now regarded in China as classics of Marxist philosophy, and he is numbered among the ten most influential Chinese intellectuals of this century. Yet, almost nothing has been written about Li Da in English.In this seminal (...) study, Knight analyzes Li Da’s contribution to the flowering of Marxist philosophy and theory in China, examining Li’s writings and placing them in the context of the Marxist tradition. Knight also explores Li Da’s philosophical relationship with Mao Zedong, who was heavily influenced by Li’s works. Through the lens of Li’s life and thought, this book provides a detailed assessment of the introduction and dissemination of Marxist philosophy and social theory in China. (shrink)
This paper considers issues raised by Elizabeth Anderson's recent critique of the position she terms luck egalitarianism. It is maintained that luck egalitarianism, once clarified and elaborated in certain regards, remains the strongest egalitarian stance. Anderson's arguments that luck egalitarians abandon both the negligent and prudent dependent caretakers fails to account for the moderate positions open to luck egalitarians and overemphasizes their commitment to unregulated market choices. The claim that luck egalitarianism insults citizens by redistributing on the grounds of paternalistic (...) beliefs, pity and envy, and by making intrusive and stigmatizing judgments of responsibility, fails accurately to characterize the luck egalitarians rationale for redistribution and relies upon luck egalitarians being insensitive to the danger of stigmatization. The luck egalitarian position is reinforced by the fact that Anderson's favoured conception of equality, democratic equality, is counterintuitively indifferent to all unchosen inequalities, including intergenerational inequalities, once bare social minima are met.

The changing world of health care finance has led to a paradigm shift in health care with health care being viewed more and more as a commodity. Many have argued that such a paradigm shift is incompatible with the very nature of medicine and health care. But such arguments raise more questions than they answer. There are important assumptions about basic concepts of health care and markets that frame such arguments.
In this review essay, Kathleen Knight Abowitz discusses three recent books related to democratic public life and schooling: Susan H. Fuhrman and Marvin Lazerson’s The Public Schools, Walter C. Parker’s Teaching Democracy: Unity and Diversity in Public Life, and Kevin McDonough and Walter Feinberg’s Education and Citizenship in Liberal‐Democratic Societies. Abowitz details how each text is inspired by meanings of liberal democracy that evolved during the Enlightenment era, in which individual rights were constitutionally coded and equality came to (...) be a powerful social and educational ideal, and how each book also takes up different sorts of Enlightenment traditions of public life and education, attempting to revitalize their meanings for public education today. Yet while these books are inspiring and instructive in numerous ways, they are also notable for the issues they fail to take into theoretical account, particularly the colonization of public spheres by the private and market‐based spheres of commerce, and the ways in which increasing ecological crisis calls for new ways of conceiving our political and educational frameworks.

Although students bring to medical school a fairly well established value system, the potential for moral growth through the medical school environment and experience is substantial. The educational environment poses a succession of developmental and adaptive tasks to be accomplished. Several of these tasks are discussed here, tasks that are value-laden and involve, directly or indirectly, the interplay of ethical theory and practice. During the past quarter century, the two influences that have had the greatest impact on the moral growth (...) and moral reasoning capacity of medical students have been the incorporation into the medical school curriculum of courses in medical humanities and the admission to medical school of an increasing number of female students. The female students have brought to medical school a level or dimension of moral reasoning (morality as care or responsibility for others) to augment the male students' focus on rights and justice considerations.
