Most of all, this book introduces readers to a genuine lover of wisdom, a philosopher who used ordinary English to address traditional problems of philosophy.

The research project described in this report represents one of the most extensive studies of character education ever undertaken, including over 10,000 students and 255 teachers in schools across England, Scotland, Northern Ireland and Wales. Research techniques consisted of a mixture of surveys, moral dilemmas and semi-structured interviews. This report explores: - The current situation in character education, both in the UK and internationally - How developed British students are with respect to moral character and the extent to which they (...) are able to understand and apply moral virtues, especially those aged 14 and 15 - How teachers in the UK understand their role in terms of students’ moral and character development - What helps or hinders the development of children’s characters according to teachers in UK schools.

“Arthur Prior’s Formal logic has been familiar to students for twenty years, but the historical section that was originally meant to accompany it was never published. In this book P. T. Geach and A. J. P. Kenny have selected from those parts of the material that were not superseded by Prior’s later publications a self-contained study of the philosophical prehistory of contemporary logic. Like Prior’s early work Logic and the Basis of Ethics the material here presented is both historical (...) and critical: Prior was not concerned to decide for us the controverted questions of logical doctrine which he discusses. He may be compared to an experienced judge summing up in a complicated civil action: the case for each side is clearly and fairly presented, and although on some issues the summing-up amounts to a pretty clear direction of the jury, the jurymen themselves are left to decide the issues. The value of such an historical survey is to be measured by the ill effects of ignoring our predecessors’ labours. The course of the philosophy of logic in the decades since Prior wrote these pages has continued to illustrate the saying that those who will not learn the history of philosophy are compelled to relive it.” - Publisher.

The eagerly-awaited second volume of The Cambridge Translations of Medieval Philosophical Texts will allow scholars and students access for the first time in English to major texts in ethics and political thought from one of the most fruitful periods of speculation and analysis in the history of western thought. Beginning with Albert the Great, who introduced the Latin west to the challenging moral philosophy and natural science of Aristotle, and concluding with the first substantial presentation in English of the revolutionary (...) ideas on property and political power of John Wyclif, the seventeen texts in this anthology offer late medieval treatments of fundamental issues in human conduct that are both conceptually subtle and of direct practical import. Special features of this volume include copious editorial introductions, an analytical index, and suggestions for further reading. This is an important resource for scholars and students of medieval philosophy, history, political science, theology and literature. (shrink)

Cannabis use in some individuals can meaningfully introduce de novo risk for the initiation of opioid use and development of opioid use disorder. These risks may be particularly high during adolescence when cannabis use may disrupt critical periods of neurodevelopment. Current research studying the combination of genetic and environmental factors involved in substance use disorders is poorly understood. More research is needed, particularly to identify which adolescents are most at risk and to develop effective interventions addressing contributing factors such as (...) trauma and psychiatric comorbidity.

Philosophical discussions of akrasia over the last fifteen years have focused on certain skeptical arguments which purport to question the possibility of a kind of akratic action which, following Pears, I call 'last ditch akrasia' (Pears [38]). An agent, succumbing to last ditch akrasia, freely, knowingly, and intentionally performs an action A against his better judgment that an incompatible action B is the better thing to do. (See Audi [1] for a detailed analysis.) Last ditch akrasia is not the only (...) kind that has been discussed. Some philosophers (Mele [32], Scaltas [48]) have been concerned with a more extreme form of akratic action, viz. one in which the agent not only judges that action B is best, but in addition intends (chooses, decides) to B. Some have even questioned whether freely acting against one's better judgment is sufficient for akratic action (Schiffer [49]: 201-3).1 Weaker types of akratic action have been discussed, though to a much lesser extent, since they are thought less problematic. Pears distinguishes last ditch akrasia from what he calls, "motivated irrational action" ([38]: 160). In cases of the latter, the akrates' rebellious desire infects his prior reasoning and thinking in such a way that his contemplated action seems to him warranted, and he acts accordingly. (For a taxonomy of cases of akratic action, see Rorty ([44])). Nor has the discussion of akrasia been restricted to akratic action. Philosophers have discussed whether akrasia can be exhibited in the formation of intentions, wants (See Audi [1]: 181-185), and beliefs (Mele [32]: ch. 8; Heil [19]). The primary focus in this paper is on last ditch akratic action. (shrink)

DUALISM AND THE PHYSICAL WORLD 257 IX. THE NATURE OF KNOWING AS A NATURAL EVENT . . 303 INDEX 323 PREFACE The principal purpose of this volume is not to present ...

(Accepted for an edition of Synthese that never saw light of day, and remained on my website. Written 2005.) Noting the status of the Law of Continuity as one of Leibniz’s most cherished axioms, Bertrand Russell charged that his philosophy nevertheless amounted to “a complete denial of the continuous”. Georg Cantor made a similar accusation of inconsistency about Leibniz’s philosophy of the actual infinite. But I argue that neither doctrine is inconsistent when the subtleties of Leibniz’s syncategorematic interpretation are properly (...) taken into account. Leibniz rejects the existence of infinite wholes: an infinite aggregate of actual things forms only a fictitious whole. Analogously, infinitesimals are only fictitious parts, this time of ideal wholes. That is, just as an actual infinity of terms can be understood syncategorematically as more terms than can be assigned a number, without there being any infinite numbers, so too the infinitely small can be given a syncategorematic interpretation by means of the Law of Continuity, without there existing any actual infinitesimals. By examining Leibniz’s justification of infinitesimals in his calculus, I argue that the syncategorematic interpretation is also applicable to series of changes, and thus exonerates Leibniz from Russell’s criticism: on this interpretation all naturally occurring transitions are continuous in that the difference between neighbouring states is smaller than any assignable. This means not that there exists a least difference, but that for any assignable finite difference, there exists a smaller one. Thus there is a true continuous transition, even though the states themselves and all assignable differences between them are actually discrete. (shrink)

Gottfried Leibniz is well known for his claim to have “rehabilitated” the substantial forms of scholastic philosophy, forging a reconciliation of the New Philosophy of Descartes, Mersenne and Gassendi with Aristotelian metaphysics (in his so-called Discourse on Metaphysics, 1686). Much less celebrated is the fact that fifty years earlier (in his Hypomnemata Physica, 1636) the Bratislavan physician and natural philosopher Daniel Sennert had already argued for the indispensability to atomism of (suitably re-interpreted) Aristotelian forms, in explicit opposition to the rejection (...) of substantial forms by his fellow atomist Sébastien Basson.1..

One of the most puzzling features of Leibniz’s deep metaphysics is the apparent contradiction between his claims that the law of continuity holds everywhere, so that in particular, change is continuous in every monad, and that “changes are not really continuous,” since successive states contradict one another. In this paper I try to show in what sense these claims can be understood as compatible. My analysis depends crucially on Leibniz’s idea that enduring states are “vague,” and abstract away from further (...) changes occurring within them at a higher resolution—consistently with his famous doctrine of "petites perceptions." As Leibniz explains further in a recently transcribed unpublished manuscript, these changes are dense within any actual duration, which is conceived as actually divided by them into states that are syncategorematically infinite in number and unassignably small. The correspondence between these unassignably small intervals between changes and the differentials of his calculus allows processes to be conceived as continuous, despite the discontinuity of the changes that occur in actuality.

One observes regulation at every biological level. Organisms, cells, and biochemical processes operate efficiently, normally wasting neither material nor energy, and adjusting their functions to external influences. Nature evidently has evolved mechanisms specifically dedicated to regulation at many levels. What is the molecular basis of this control?In the 1950s these molecular control mechanisms began to be explored seriously. The discoveries of feedback inhibition of enzyme activity were important because they gave an initial example of how regulation is achieved at the (...) molecular level. We showed that certain enzymes are composed of two parts, one for catalysis and another distinct part present only to regulate this catalysis. Catalytic activity can be either stimulated or inhibited when a small molecule in the environment combines with the enzyme's regulatory site. In particular, a final product of a metabolic pathway generates a feedback loop which automatically limits its own excessive production, by combining with the regulatory site of an early enzyme in that pathway. Later studies showed that catalytic and regulatory structures of some enzymes could be separated physically.The discovery of regulatory sites and their interaction with molecules unrelated to their substrates was the basis for the generalized allosteric concept. This concept extends the regulatory site idea to a wide variety of processes such as control of gene expression, hormone action, and cellular growth. (shrink)

The Pajama (Pardee, Jacob, Monod) experiment provided a breakthrough in our understanding of the molecular mechanisms by which gene expression is regulated. Today, twenty‐five years later it provides a paradigm for thinking about problems of gene expression, such as growth regulation and differentiation. From this experiment emerged entities such as repressors, regulatory genes, the operon as a group of jointly controlled genes, and messenger RNA.
