We investigated the automaticity of implicit sequence learning by varying perceptual load in a pure perceptual sequence learning paradigm. Participants responded to the randomly changing identity of a target, while the irrelevant target location was structured. In Experiment 1, the target was presented under low or high perceptual load during training, whereas testing occurred without load. Unexpectedly, no sequence learning was observed. In Experiment 2, perceptual load was introduced during the test phase to determine whether load is required to express (...) perceptual knowledge. Learning itself was unaffected by visuospatial demands, but more learning was expressed under high load test conditions. In Experiment 3, we demonstrated that perceptual load is not required for the acquisition of perceptual sequence knowledge. These findings suggest that perceptual load does not mediate the perceptual sequence learning process itself, supporting the automaticity of implicit learning, but is mandatory for the expression of pure perceptual sequence knowledge.

Peter Abelard was one of the most influential writers and thinkers of the twelfth century, famed for his skill in logic as well as his romance with Heloise. His Collationes - or Dialogue between a Christian, a Philosopher, and a Jew - is remarkable for the boldness of its conception and thought.
In an oft-quoted passage from The Principles of Morals and Legislation, Jeremy Bentham addresses the issue of our treatment of animals with the following words: ‘the question is not, Can they reason? nor, can they talk? but, Can they suffer?’ The point is well taken, for surely if animals suffer, they are legitimate objects of our moral concern. It is curious therefore, given the current interest in the moral status of animals, that Bentham's question has been assumed to be merely (...) rhetorical. No-one has seriously examined the claim, central to arguments for animal liberation and animal rights, that animals actually feel pain. Peter Singer's Animal Liberation is perhaps typical in this regard. His treatment of the issue covers a scant seven pages, after which he summarily announces that ‘there are no good reasons, scientific or philosophical, for denying that animals feel pain’. In this paper I shall suggest that the issue of animal pain is not so easily dispensed with, and that the evidence brought forward to demonstrate that animals feel pain is far from conclusive.

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 philosopher. He championed the use of reason in matters of faith (he was the first to use ‘theology’ in its modern sense), and his systematic treatment of religious doctrines are as remarkable for their philosophical penetration and subtlety as they are for their audacity. Abelard seemed larger than life to his contemporaries: his quick wit, sharp tongue, perfect memory, and boundless arrogance made him unbeatable in debate — he was said by supporter and detractor alike never to have lost an argument — and the force of his personality impressed itself vividly on all with whom he came into contact. His luckless affair with Héloïse made him a tragic figure of romance, and his conflict with Bernard of Clairvaux over reason and religion made him the hero of the Enlightenment. For all his colourful life, though, his philosophical achievements are the cornerstone of his fame. (shrink)
Histories of philosophy frequently depict the later eleventh century as the scene of a series of bouts between dialecticians and anti-dialecticians — Berengar vs. Lanfranc, Roscelin vs. Anselm — preliminaries to the twelfth century welterweight contest between Abelard and St. Bernard and — dare one say? — the thirteenth century heavy-weight championship between St. Thomas and St. Bonaventure.The bouts took place — no question about that — but whether the contestants can properly be characterized as dialecticians and anti-dialecticians is less (...) certain. Dialectics is logic, the third part of the trivium, and increasingly cultivated in the eleventh century; men like Berengar and Roscelin were plainly eager to apply the logical tools with which they had been equipped to the solution of intellectual problems. In particular they undertook the solution of certain central problems of theology — Berengar that of the Eucharist and Roscelin that of the Trinity — and it was this, we are told, that aroused the ire of the anti-dialecticians: if the aim of the dialecticians was to lay bare the mysteries of faith to the light of reason that of the anti-dialecticians was to protect those same mysteries from profanation.

The doyen of living English philosophers, by these reflections, took hold of and changed the outlook of a good many other philosophers, if not quite enough. He did so, essentially, by assuming that talk of freedom and responsibility is talk not of facts or truths, in a certain sense, but of our attitudes. His more explicit concern was to look again at the question of whether determinism and freedom are consistent with one another -- by shifting attention to certain personal (...) rather than moral attitudes, first of all gratitude and resentment. In the end, he arrived at a kind of Compatibilist or, as he says, Optimist conclusion. That is no doubt a recommendation but not the largest recommendation of this splendidly rich piece of philosophy. (shrink)
Peter Singer is probably the best-known and most controversial ethicist in the world today. He rigorously applies utilitarian moral theory to issues such as world poverty, the environment, abortion, euthanasia and, most famously, animal welfare. He has also written a book about his grandfather, David Oppenheim, who died in Theresienstadt concentration camp. He is Ira W. DeCamp Professor of Bioethics at Princeton University.

The primary aim of this important study is to produce a reliable account of Peter Martyr’s life before he left Italy in 1542. Earlier biographers had been content to follow the Swiss Calvinist Josiah Simler, who knew Peter Martyr in later years, delivered his funeral oration and published it in 1563. Dr McNair has tried ‘to delve beneath Simler to contemporary records’. He has discovered, for example, that Peter Martyr was born in 1499 not, as is usually (...) said, in 1500. He has been concerned to find out when Peter Martyr left his order and his Church, suggesting that there is little reason to believe that his apostasy began in his years at the University of Padua, 1518-26; it was in Naples, between 1537 and 1540, when he came to know Juan de Valdés, that Peter Martyr’s conversion took place. ‘He arrived a reformer after the order of Ximénez, he left a reformer after the order of Zwingli’, writes Dr McNair, meaning by this the Zwingli of the years immediately before 1523, when he wished to go further than Erasmus but not so far as Luther.

Alan C. LoveDarwinian calisthenicsAn athlete engages in calisthenics as part of basic training and as a preliminary to more advanced or intense activity. Whether it is stretching, lunges, crunches, or push-ups, routine calisthenics provide a baseline of strength and flexibility that prevent a variety of injuries that might otherwise be incurred. Peter Bowler has spent 40 years doing Darwinian calisthenics, researching and writing on the development of evolutionary ideas with special attention to Darwin and subsequent filiations among scientists exploring (...) evolution . Therefore, we would expect that when Bowler engages in a counterfactual history—imagining a world without Darwin—he is able to avoid historical injury and generate novel insights. My assessment is that the results are mixed. Before we can see why, it is necessary to walk briskly through the main contours of his argument.Bowler begins with an apologia for a counterfactual appr .. (shrink)
The paper discusses al-Kindī's response to doctrines held by contemporary theologians of the Mu‘tazilite school: divine attributes, creation, and freedom. In the first section it is argued that, despite his broadly negative theology, al-Kindī recognizes a special kind of “essential” positive attribute belonging to God. The second section argues that al-Kindī agreed with the Mu‘tazila in holding that something may not yet exist but still be an object of God's knowledge and power. Also it presents a new parallel between al-Kindī (...) and John Philoponus. The third section gives an interpretation of al-Kindī as a compatibilist, in other words as holding that humans may be free even though their actions are necessitated. In all three cases, it is argued, al-Kindī is close to the Mu‘tazilite point of view, though he departs from them in the arguments he gives for that point of view. (shrink)
Define ‘het’ as a predicate that truly applies to itself if and only if it does not truly apply to itself and which also truly applies to any predicate that does not truly apply to its own name. We know that the attempted definition of ‘hes’ is a failure, and so a fortiori is that of ‘het’. Similarly, there is no Qussell class which contains itself as a member if and only if it does not contain itself as a member, (...) so a fortiori there is no Russell Class which contains itself as a member if and only if it does not contain itself as a member and which also contains all and only non-self-membered classes (such as the class of dogs). The second conjunct in both the definition of ‘het’ and of the Russell class cannot revive a definition doomed to failure. Likewise, the ‘definition’ of n as ‘n > 1 iff n < 1’ fails, and the attempted definition of m as ‘m > 1 iff m < 1 and m is prime’ is hopeless too; its final clause buys it no respectability. (shrink)
You don't say much about who you are teaching, or what subject you teach, but you do seem to see a need to justify what you are doing. Perhaps you're teaching underprivileged children, opening their minds to possibilities that might otherwise never have occurred to them. Or maybe you're teaching the children of affluent families and opening their eyes to the big moral issues they will face in life — like global poverty, and climate change. If you're doing something like (...) this, then stick with it. Giving money isn't the only way to make a difference. (shrink)
