    Unintended Changes in Cognition, Mood, and Behavior Arising from Cell-Based Interventions for Neurological Conditions: Ethical Challenges
    with P. S. Duggan, A. W. Siegel, D. M. Blass, H. Bok, J. T. Coyle, R. Faden, J. Finkel, J. D. Gearhart, H. T. Greely, A. Hillis, A. Hoke, R. Johnson, M. Johnston, J. Kahn, and D. Kerr
    American Journal of Bioethics 9 (5): 31-36. 2009.
    The prospect of using cell-based interventions to treat neurological conditions raises several important ethical and policy questions. In this target article, we focus on issues related to the unique constellation of traits that characterize CBIs targeted at the central nervous system. In particular, there is at least a theoretical prospect that these cells will alter the recipients' cognition, mood, and behavior—brain functions that are central to our concept of the self. The potential for such…Read more

    This book considers how a dwelling can protect and promote both our anxieties and our relationships. Both essays use a non-traditional literature to explore being alone and being with others, rather than relying on the social science literature, and offer a distinct and original contribution to the housing studies literature.

    Peter Abelard
    Stanford Encyclopedia of Philosophy. 2008.
    Peter Abelard (1079 – 21 April 1142) [‘Abailard’ or ‘Abaelard’ or ‘Habalaarz’ and so on] was the pre-eminent philosopher and theologian of the twelfth century. The teacher of his generation, he was also famous as a poet and a musician. Prior to the recovery of Aristotle, he brought the native Latin tradition in philosophy to its highest pitch. His genius was evident in all he did. He is, arguably, the greatest logician of the Middle Ages and is equally famous as the first great nominalist philos…Read more

    Abelard on Mental Language
    American Catholic Philosophical Quarterly 81 (2): 169-187. 2007.
    I argue that Abelard was the author of the first theory of mental language in the Middle Ages, devising a “language of thought” to provide the semantics for ordinary languages, based on the idea that thoughts have linguistic character. I examine Abelard’s semantic framework with special attention to his principle of compositionality (the meaning of a whole is a function of the meanings of the parts); the results are then applied to Abelard’s distinction between complete and incomplete expression…Read more

    Augustine on testimony
    Canadian Journal of Philosophy 39 (2). 2009.
    Philosophical work on testimony has flourished in recent years. Testimony roughly involves a source affirming or stating something in an attempt to transfer information to one or more persons. It is often said that the topic of testimony has been neglected throughout most of the history of philosophy, aside from contributions by David Hume (1711–1776) and Thomas Reid (1710–1796).1 True as this may be, Hume and Reid aren’t the only ones who deserve a tip of the hat for recognizing the importance …Read more

    Duns Scotus on Singular Essences
    Medioevo 30 111-137. 2005.
    Socrates, for example, has an essence that includes more than his human nature, which is his specific essence; he has an essence proper to himself alone, an essence that cannot be had by anyone else. Although Socrates does have singular (individualized) forms, his singular essence is not a form—there is no form Socrateity for the singular essence parallelling the form humanity for the specific essence. Instead, Socrates has his singular essence in consequence of being an individual, that is, in …Read more

    That it is: According to the Commentator, Met. 7 com. 11 ([Iuntina 8 fol. 76r]): The definition is the same as the substance of the thing. Hence it is in some way outside the soul, and consequently all its parts are in some way outside the soul. But the definition is composed of universals. Hence [the universal is outside the soul]

    In one corner Socrates; in the other, on the mat, his cat Felix. Socrates, of course, thinks (correctly) that Felix the Cat is on the mat. But there’s the rub. For Socrates to think that Felix is on the mat, he has to be able to think about Felix, that is, he has to have some sort of cognitive grasp of an individual — and not just any individual, but Felix himself. How is that possible? What is going on when we think about things?

    Mediaeval psychological theory was a “faculty psychology”: a confederation of semiautonomous sub-personal agents, the interaction of which constitutes our psychological experience. One such faculty was intellective appetite, that is, the will. On what grounds was the will taken to be a distinct faculty? After a brief survey of Aristotle's criteria for identifying and distinguishing mental faculties, I look in some detail at the mainstream mediaeval view, given clear expression by Thomas Aquinas,…Read more

    [1] In twelve quite demanding chapters, outstanding scholars provide an overall view of the key issues of Scotus’s philosophical thought. To this a very concise introduction is added, concerning the life and works of John Duns (very good, especially the survey of works and the information on critical editions etc.). Throughout the book, I find the information clear and the difficult topics well explained. Moreover, the volume gives a quick entrance to the vast literature. Among the topics discus…Read more

    Aristotle was the first thinker to devise a logical system. He drew upon the emphasis on universal definition found in Socrates, the use of reductio ad absurdum in Zeno of Elea, claims about propositional structure and negation in Parmenides and Plato, and the body of argumentative techniques found in legal reasoning and geometrical proof. Yet the theory presented in Aristotle’s five treatises known as the Organon—the Categories, the De interpretatione, the Prior Analytics, the Posterior Analyti…Read more

    B      opens his discussion of the problem of universals, in his second commentary on Porphyry’s Isagoge, with a destructive dilemma: genera and species either exist or are concepts; but they can neither exist nor be soundly conceived; therefore the enquiry into them should be abandoned (In Isag. maior . ). Boethius’ strategy to get around this dilemma is well known. He follows the lead of Alexander of Aphrodisias, distinguishing several ways in which genera and species can be conceive…Read more

    In the first volume of Capital, Marx introduces a labor theory of value. The theory is supposed to form the basis of his “laying bare” the “inner workings” of capitalism. The theory rests on two claims, and at the outset Marx uses it to explain four features of capitalist production. Yet by the end of the final volume of Capital, he abandons both claims and offers alternative accounts of all four features of capitalism. We hold that Marx’s introduction of the labor theory of value is not the presen…Read more

    The works translated here deal with two major themes in the thinking of St Augustine : free will and divine grace. On the one hand, free will enables human beings to make their own choices; on the other hand, God's grace is required for these choices to be efficacious. 'On the Free Choice of the Will', 'On Grace and Free Choice', 'On Reprimand and Grace' and 'On the Gift of Perseverance' set out Augustine's theory of human responsibility, and sketch a subtle reconciliation of will and grace. Thi…Read more

    Abelardo eredita dall'Isagoge di Porfirio una questione filosofica fondamentale, relativa al problema degli universali, posto al centro della metafisica. Abelardo si pone subito fuori da questa linea interpretativa. L'A. esamina le risposte di Abelardo ai quattro quesiti di Porfirio formulati all'inizio dell'Isagoge punto per punto, attraverso l'esame di Dialectica, Logica «Ingredientibus» nella parte relativa al commento all'Isagoge, in rapporto con il Commentarius maior in Isagogen Porphyrii d…Read more

    If we do stop to think on housing, what do we see? What is housing and what does it do? These seem deceptively simple questions, but they are often left unanswered. The reason for this is that a lot of discourse on housing is really a concern for policy-making and the critical evaluation of existing policies. Discourse, is not, properly speaking, on housing at all. It is concerned with provision, distribution and access, but this thinking on housing stops at the front door. It is only concerned …Read more
