This study examined the hypothesis that conditional reasoning involves visual short-term memory resources (Johnson-Laird, 1985). A total of 147 university students were given measures of verbal and visual short-term memory capacity and a series of concrete and abstract conditional reasoning problems. Results indicate that there is a positive correlation between verbal working memory capacity and reasoning with both concrete and abstract premises. A positive correlation was also obtained between visual working memory capacity and reasoning with concrete premises.

Because of the difficulty posed by the contrast between the search for truth and truth itself, Michael Polanyi believes that we must alter the foundation of epistemology to include as essential to the very nature of mind, the kind of groping that constitutes the recognition of a problem. This collection of essays, assembled by Marjorie Grene, exemplifies the development of Polanyi's theory of knowledge which was first presented in Science, Faith, and Society and later systematized in Personal Knowledge. Polanyi (...) believes that the dilemma of the modern mind arises from the peculiar relation between the positivist claim for total objectivity in scientific knowledge and the unprecedented moral dynamism characterizing the social and political aspirations of the last century. The first part of Knowing and Being deals with this theme. Part two develops Polanyi's idea that centralization is incompatible with the life of science as well as his views on the role of tradition and authority in science. The essays on tacit knowing in Part Three proceed directly from his preoccupation with the nature of scientific discovery and reveal a pervasive substructure of all intelligent behavior. Polanyi believes that all knowing involves movement from internal clues to external evidence. Therefore, to explain the process of knowing, we must develop a theory of the nature of living things in general, including an account of that aspect of living things we call "mind." Part Four elaborates upon this theme. (shrink)

In various areas of Anglo-American law, legal liability turns on causation. In torts and contracts, we are each liable only for those harms we have caused by the actions that breach our legal duties. Such doctrines explicitly make causation an element of liability. In criminal law, sometimes the causal element for liability is equally explicit, as when a statute makes punishable any act that has “ caused … abuse to the child….” More often, the causal element in criminal liability is (...) more implicit, as when criminal statutes prohibit killings, maimings, rapings, burnings, etc. Such causally complex action verbs are correctly applied only to defendants who have caused death, caused disfigurement, caused penetration, caused fire damage, etc. (shrink)

Michael Ridge presents an original expressivist theory of normative judgments--Ecumenical Expressivism--which offers distinctive treatments of key problems in metaethics, semantics, and practical reasoning. He argues that normative judgments are hybrid states partly constituted by ordinary beliefs and partly constituted by desire-like states.

Freud justified his extensive theorizing about dreams by the observation that they were “the royal road” to something much more general: namely, our unconscious mental life. The current preoccupation with the theory of excuse in criminal law scholarship can be given a similar justification, for the excuses are the royal road to theories of responsibility generally. The thought is that if we understand why we excuse in certain situations but not others, we will have also gained a much more general (...) insight into the nature of responsibility itself. Nowhere has this thought been more evident than in the century-old focus of criminal law theoreticians on the excuse of insanity, a focus that could not be justified by the importance of the excuse itself. In this paper I wish to isolate two theories of excuse, each of which instantiates its own distinctive theory of responsibility. One is what I shall call the choice theory of excuse, according to which one is excused for the doing of a wrongful action because and only because at the moment of such action's performance, one did not have sufficient capacity or opportunity to make the choice to do otherwise. Such a choice theory of excuse instantiates a more general theory of responsibility, according to which we are responsible for wrongs we freely choose to do, and not responsible for wrongs we lacked the freedom to avoid doing. The second I shall call the character theory of excuse, according to which one is excused for the doing of a wrongful action because and only because such action is not determined by those enduring attributes of ourselves we call our characters.

In the Trolley Case, as devised by Philippa Foot and modified by Judith Jarvis Thomson, a runaway trolley is headed down a main track and will hit and kill five unless you divert it onto a side track, where it will hit and kill one.

This paper deals with Ludwik Fleck’s theory of thought styles and Michael Polanyi’s theory of tacit knowledge. Though both concepts have been very influential for science studies in general, and both have been subject to numerous interpretations, their accounts have, somewhat surprisingly, hardly been comparatively analyzed. Both Fleck and Polanyi relied on the physiology and psychology of the senses in order to show that scientific knowledge follows less the path of logical principles than the path of accepting or rejecting (...) specific conventions, where these may be psychologically or sociologically grounded. It is my aim to show that similarities and differences between Fleck and Polanyi are to be seen in the specific historical and political context in which they worked. Both authors, I shall argue, emphasized the relevance of perception in close connection to their respective understanding of science, freedom, and democracy. (shrink)

In this work the distinguished physical chemist and philosopher, Michael Polanyi, demonstrates that the scientist's personal participation in his knowledge, in both its discovery and its validation, is an indispensable part of science itself. Even in the exact sciences, "knowing" is an art, of which the skill of the knower, guided by his personal commitment and his passionate sense of increasing contact with reality, is a logically necessary part. In the biological and social sciences this becomes even more evident. (...) The tendency to make knowledge impersonal in our culture has split fact from value, science from humanity. Polanyi wishes to substitute for the objective, impersonal ideal of scientific detachment an alternative ideal which gives attention to the personal involvement of the knower in all acts of understanding. His book should help to restore science to its rightful place in an integrated culture, as part of the whole person's continuing endeavor to make sense of the totality of his experience. In honor of this work and his The Study of Man Polanyi was presented with the Lecomte de Noüy Award for 1959. (shrink)

In this book Michael McKenna advances a new theory of moral responsibility, one that builds upon the work of P.F. Strawson.

Michael S. Brady offers a new account of the role of emotions in our lives. He argues that emotional experiences do not give us information in the same way that perceptual experiences do. Instead, they serve our epistemic needs by capturing our attention and facilitating a reappraisal of the evaluative information that emotions themselves provide.

Michael Ryan (d. 1840) remains one of the most mysterious figures in the history of medical ethics, despite the fact that he was the only British physician during the middle years of the 19th century to write about ethics in a systematic way. Michael Ryan’s Writings on Medical Ethics offers both an annotated reprint of his key ethical writings, and an extensive introductory essay that fills in many previously unknown details of Ryan’s life, analyzes the significance of his (...) ethical works, and places him within the historical trajectory of the field of medical ethics.

Michael Ignatieff draws on his extensive experience as a writer and commentator on world affairs to present a penetrating account of the successes, failures, and prospects of the human rights revolution. Since the United Nations adopted the Universal Declaration of Human Rights in 1948, this revolution has brought the world moral progress and broken the nation-state's monopoly on the conduct of international affairs. But it has also faced challenges. Ignatieff argues that human rights activists have rightly drawn criticism from (...) Asia, the Islamic world, and within the West itself for being overambitious and unwilling to accept limits. It is now time, he writes, for activists to embrace a more modest agenda and to reestablish the balance between the rights of states and the rights of citizens.Ignatieff begins by examining the politics of human rights, assessing when it is appropriate to use the fact of human rights abuse to justify intervention in other countries. He then explores the ideas that underpin human rights, warning that human rights must not become an idolatry. In the spirit of Isaiah Berlin, he argues that human rights can command universal assent only if they are designed to protect and enhance the capacity of individuals to lead the lives they wish. By embracing this approach and recognizing that state sovereignty is the best guarantee against chaos, Ignatieff concludes, Western nations will have a better chance of extending the real progress of the past fifty years. Throughout, Ignatieff balances idealism with a sure sense of practical reality earned from his years of travel in zones of war and political turmoil around the globe.Based on the Tanner Lectures that Ignatieff delivered at Princeton University's Center for Human Values in 2000, the book includes two chapters by Ignatieff, an introduction by Amy Gutmann, comments by four leading scholars--K. Anthony Appiah, David A. Hollinger, Thomas W. Laqueur, and Diane F. Orentlicher--and a response by Ignatieff. (shrink)

Human beings act together in characteristic ways that matter to us a great deal. This book explores the conceptual, metaphysical and normative foundations of such sociality. It argues that appeal to the planning structures involved in our individual, temporally extended agency provides substantial resources for understanding these foundations of our sociality.

In _Reconstructing the Cognitive World_, Michael Wheeler argues that we should turn away from the generically Cartesian philosophical foundations of much contemporary cognitive science research and proposes instead a Heideggerian approach. Wheeler begins with an interpretation of Descartes. He defines Cartesian psychology as a conceptual framework of explanatory principles and shows how each of these principles is part of the deep assumptions of orthodox cognitive science. Wheeler then turns to Heidegger's radically non-Cartesian account of everyday cognition, which, he argues, (...) can be used to articulate the philosophical foundations of a genuinely non-Cartesian cognitive science. Finding that Heidegger's critique of Cartesian thinking falls short, even when supported by Hubert Dreyfus's influential critique of orthodox artificial intelligence, Wheeler suggests a new Heideggerian approach. He points to recent research in "embodied-embedded" cognitive science and proposes a Heideggerian framework to identify, amplify, and clarify the underlying philosophical foundations of this new work. He focuses much of his investigation on recent work in artificial intelligence-oriented robotics, discussing, among other topics, the nature and status of representational explanation, and whether cognition is computation rather than a noncomputational phenomenon best described in the language of dynamical systems theory. Wheeler's argument draws on analytic philosophy, continental philosophy, and empirical work to "reconstruct" the philosophical foundations of cognitive science in a time of a fundamental shift away from a generically Cartesian approach. His analysis demonstrates that Heideggerian continental philosophy and naturalistic cognitive science need not be mutually exclusive and shows further that a Heideggerian framework can act as the "conceptual glue" for new work in cognitive science.

This is an obituary for Michael H. Robins.

If observation is ‘theory-laden’, how can there be ‘observationally equivalent theories’? How can the observations ‘laden’ by one theory be ‘the same as’ those ‘laden’ by another? The answer might lie in the expressibility of observationally equivalent theories in a common mathematical formalism.

Miranda Fricker appeals to the idea of moral-epistemic disappointment in order to show how our practices of moral appraisal can be sensitive to cultural and historical contingency. In particular, she thinks that moral-epistemic disappointment allows us to avoid the extremes of crude moralism and a relativism of distance. In my response I want to investigate what disappointment is, and whether it can constitute a form of focused moral appraisal in the way that Fricker imagines. I will argue that Fricker is (...) unable to appeal to disappointment as standardly understood, but that there is a more plausible way of understanding the notion that she can employ. There are, nevertheless, significant worries about the capacity of disappointment in this sense to function as a form of moral appraisal. I will argue, finally, that even if Fricker can address these worries, her position might end up closer to moralism than she would like. (shrink)
