Body integrity identity disorder is a very rare condition in which people experience long-standing anguish because there is a mismatch between their bodies and their internal image of how their bodies should be. Most typically, these people are deeply distressed by the presence of what they openly acknowledge as a perfectly normal leg. Some with the condition request that their limb be amputated. 1 We and others have argued that such requests should be acceded to in carefully selected patients.1–4 Consistent (...) with this view, a group at the University of Sydney is developing a programme to better understand and treat BIID and to offer amputation if appropriate. In a recent paper, Patrone argues that such amputations should be prohibited.5 He suggests that authors supporting amputation in BIID depend on analogies with more familiar conditions and then claim that the ‘the desires, choices and requests of BIID patients should be held to exactly the same standards and treated with exactly the same respect as the desires, choices and requests of any more conventional patient’.5 He believes that these analogies are invalid and that therefore the arguments for amputation are invalid.Patrone concentrates a great deal upon whether a decision to have a particular medical intervention is to be regarded as ‘rational’. Unfortunately, he makes no attempt to define what he …. (shrink)

The central project of the Critique of Pure Reason is to answer two sets of questions: What can we know and how can we know it? and What can't we know and why can't we know it? The essays in this collection are intended to help students read the Critique of Pure Reason with a greater understanding of its central themes and arguments, and with some awareness of important lines of criticism of those themes and arguments.

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)
