According to the ambitious Predictive Theory of the Mind the brain generates models that it tests against experience and corrects to makes them evermore probably accurate of encountered experience. It neatly explains why we cannot tickle ourselves. The convincingness of that example is compromised by its essentially non-cognitive nature whereby an explanation not involving predictive models might do just as well. More telling confirmation of the theory is the essentially cognitive phenomenon of our inability to play chess against ourselves. This (...) may stand as a paradigm of the power of the theory in explaining the central mental phenomenon of abstract cognition. (shrink)

The purpose here is to cast doubt on some utilitarian non‐rights‐based arguments that are generally thought to be decisive objections to voluntary and non‐voluntary euthanasia. The aim is not to prove that euthanasia is morally vindicated (although I think rights‐based arguments can do this) but rather to contend that such arguments, far from being decisively anti‐euthanasia, can be made to point equally in the opposite direction.

Recent studies indicate that mammalian chromosomes contain discretecis‐acting loci that control replication timing, mitotic condensation, and stability of entire chromosomes. Disruption of the large non‐coding RNA gene ASAR6 results in late replication, an under‐condensed appearance during mitosis, and structural instability of human chromosome 6. Similarly, disruption of the mouse Xist gene in adult somatic cells results in a late replication and instability phenotype on the X chromosome. ASAR6 shares many characteristics with Xist, including random mono‐allelic expression and asynchronous replication timing. (...) Additional “chromosome engineering” studies indicate that certain chromosome rearrangements affecting many different chromosomes display this abnormal replication and instability phenotype. These observations suggest that all mammalian chromosomes contain “inactivation/stability centers” that control proper replication, condensation, and stability of individual chromosomes. Therefore, mammalian chromosomes contain four types ofcis‐acting elements, origins, telomeres, centromeres, and “inactivation/stability centers”, all functioning to ensure proper replication, condensation, segregation, and stability of individual chromosomes.

A historical investigation of the exclusion of Africa and Asia from modern histories of philosophy.

Any attempt to describe a "best health service' must make political assumptions. For example, should it help everyone? Do different people have different entitlements to its support? Should its help be offered according to need, value for money or ability to benefit? These assumptions are not always clear to health service decision-makers immersed in clinical and economic technicalities, so HCA invited two philosophers --John Shand and David Seedhouse -- to engage in conversation about the political philosophy of health care.

Philosophy makes no progress. It fails to do so in the way science and mathematics make progress. By “no progress” is meant that there is no successive advance of a well-established body of knowledge—no views are definitively established or definitively refuted. Yet philosophers often talk and act as if the subject makes progress, and that its point and value lies in its doing so, while in fact they also approach the subject in ways that clearly contradict any claim to progress. (...) This article presents evidence for, and a theoretical explanation of, the view that philosophy makes no progress, concluding with an account of what philosophy is and what the point and value of it is. Philosophy should not be shy about being what it is, nor should it pretend to be what it is not. What it is should be reflected in philosophizing and the way it is taught. (shrink)

Vaesen infers unique properties of mind from the appearance of specific cultural innovation – a correlation without causal direction. Shifts in habitat, population density, and group dynamics are the only independently verifiable incentives for changes in cultural practices. The transition from Acheulean to Late Stone Age technologies requires that we consider how population and social dynamics affect cultural innovation and mental function.

The first English translation of Fichte’s second set of 1804 lectures on the Wissenschaftslehre.

Philosophy and Philosophers is an important introduction to Western philosophy aimed at those who are unfamiliar with the nature of philosophy and its history. It is organized around the main schools of philosophical thought and ranges from ancient Greece, through the explosion of ideas in the seventeenth century, to the Enlightenment and the challenge of twentieth-century philosophy. In each chapter John Shand assesses the contribution of a single philosopher, paying particular attention to the key areas of the theory of (...) knowledge, the nature of reality, and the nature of philosophy itself. An extensive annotated bibliography serves as a helpful guide to works by and about the philosophers discussed. Accessible and clearly written, this survey of the ideas of the major thinkers of the western world will be invaluable as a reference source. (shrink)

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.

The primary focus here is romantic love, but it may be applied to other cases of love such as those within a family. The first issue is whether love is a non-rational occurrence leading to a state of affairs to which the normative constrains of reason do not apply. If one assumes that reasons are relevant to determining love, then the second issue is the manner in which love is and should be reasonable and governed by the indications of reason. (...) It is contended that our conception of love is inherently contradictory. Depending on circumstances, we want love to be both a non-rational occurrence beyond reason and something normative such that the indications of reasons are relevant to determining and assessing it. We alternate between the two treatments of love and in so doing love can function in our lives. The incoherence is accommodated by each treatment or view of love being one of as if. This allows us to live with love in a manner whereby we do not have to definitively commit to either alternative, so we have a dipolar as if concept of love. Sometimes we view love as if reasons were beside the point and at others we view love as if it were rightly subject to the indications of reason. (shrink)

In this attempt to deal with the problem of free will Tallis identifies intentionality as a feature of our lives that cannot be explained by deterministic, natural, physical, causal laws. Our ability to think about the world, and not merely be objects subject to it, gives us room for manoeuvre for free thought and action. Science, far from being antagonistic to the possibility of free will as it is usually presented through its deterministic explanations, is a manifestation of our freedom (...) and could not exist without it. However, doubts arise for the argument owing to a lack of explanation as to how freedom is possible no matter how persuasively we are shown that it appears to be. That is, what kind of world would it have to be for freedom to exist and be explicable. I conclude with my own view, alluded to by Tallis, but not followed up, that the problem with the scientific worldview is that it is wedded to objectivity as the only stance deemed veridical as to the nature of reality, one which therefore cannot by necessity allow subjects or freedom. As freedom is a property of subjects, the scientific worldview cannot allow for freedom. Once the condition is dropped that only the objectively knowable can be real, freedom also may be real, defined as a knowable property of our subjectivity. There is no need to deny physicalism if the definition of it is released from the epistemic bonds of objectivity and we hold that some physical properties may be known subjectively, namely those that characterize our subjective life.

The ‘hard’ problem of consciousness is the seemingly intractable one of explaining the properties of consciousness in terms of the properties of physical objects. This is often seen mistakenly as a metaphysical problem, whereby the properties of physical things are of such a nature and so unlike mental properties that it is difficult to understand how the physical could ever explain consciousness. This view of the physical is not however the true reason for the hardness of the problem, rather it (...) is epistemic, that of defining the physical as those features of the world that may be known objectively, coupled with the contention that only those objectively known properties are real. This makes the explanation of subjective consciousness in terms physical properties not just hard but impossible. The answer is to hold that the world is indeed all physical, but have the physical no longer defined as what may be known only objectively, and hold that some physical properties may be known subjectively. This eliminates the hard problem of consciousness as it is no longer required that the explanation of subjective properties of physical things be in terms of the objective properties of physical things.

Scientists and laypeople alike use the sense of understanding that an explanation conveys as a cue to good or correct explanation. Although the occurrence of this sense or feeling of understanding is neither necessary nor sufficient for good explanation, it does drive judgments of the plausibility and, ultimately, the acceptability, of an explanation. This paper presents evidence that the sense of understanding is in part the routine consequence of two well-documented biases in cognitive psychology: overconfidence and hindsight. In light of (...) the prevalence of counterfeit understanding in the history of science, I argue that many forms of cognitive achievement do not involve a sense of understanding, and that only the truth or accuracy of an explanation make the sense of understanding a valid cue to genuine understanding.

The purpose of this text is to draw attention to eight forgotten heroes: William C. Bagley, Charles DeGarmo, David Felmley, William Torrey Harris, Isaac L. Kandel, Charles McMurry, William C. Ruediger, and Edward Austin Sheldon. They have been marginalized from our profession, and drawing upon their legacy is the best hope for restoring the profession of teaching today. This work also includes a chapter at the end of the book entitled "John Dewey's Forgotten Essays." The audience for this book includes: (...) 1) classroom teachers, 2) school administrators, 3) teacher educators, 4) deans and other university administrators, 5) college and university presidents, 6) legislators, 7) historians of education, 8) curriculum specialists, 9) specialists in teacher training, and 10) the general public.

Knowledge, like other things of value, can be faked. According to Hawley (2011), know-how is harder to fake than knowledge-that, given that merely apparent propositional knowledge is in general more resilient to our attempts at successful detection than are corresponding attempts to fake know-how. While Hawley’s reasoning for a kind of detection resilience asymmetry between know-how and know-that looks initially plausible, it should ultimately be resisted. In showing why, we outline different ways in which know-how can be faked even when (...) a given performance is successful; and in doing so, we distinguish how know-how can be faked (no less than know-that) via upstream and downstream indicators of its presence, and within each of these categories, we’ll distinguish (in connection with detection resilience) both faking symptoms and (various kinds of) criteria. The unappreciated resilience of faked knowledge-how to successful detection highlights a largely overlooked dimension of social-epistemic risk – risk we face not just in our capacity as recipients of testimony, but in our capacity as both (would-be) apprentices and clients of knowledge-how.
