Aim: Patients with advanced cancer need information about end-of-life treatment options in order to make informed decisions. Clinicians vary in the frequency with which they initiate these discussions.Patients and methods: As part of a long-term longitudinal study, patients with an expected 2-year survival of less than 50% who had advanced gastrointestinal or lung cancer or amyotrophic lateral sclerosis were interviewed. Each patient’s medical record was reviewed at enrollment and at 3 months for evidence of the discussion of patient wishes concerning (...) ventilator support, artificial nutrition and hydration , resuscitation and hospice care. A Kaplan–Meier analysis was also performed and 2-year survival calculated.Results: 60 cancer and 32 ALS patients were enrolled. ALS patients were more likely than cancer patients to have evidence of discussion about their wishes for ventilator support , ANH , DNR and hospice care . At 6 months, 91% of ALS patients were alive compared with 62% of cancer patients; at 2 years, 63% of ALS patients were alive compared with 23% of cancer patients .Conclusions: Cancer patients were less likely than ALS patients to have had documented advanced care planning discussions despite worse survival. This may reflect perceptions that ALS has a more predictable course, that advanced cancer has a greater number of treatment options, or differing views about hope. Nevertheless, cancer patients may be less adequately prepared for end-of-life decision-making. (shrink)

As we know, the category of practice is a focal point in Marxist philosophy. The revolutionary upheaval in philosophy carried out by Marxism involves the interpretation of the essence of practice and its role in the process of cognition. In the fifty years of the development of Soviet philosophy, much has been done to clarify the nature of this problem, to render it concrete and work it out. The development of Marxist philosophical thought in other countries has also yielded much.

This article, written in honor of Fritz Rohrlich, briefly surveys the role of topology in physics.

In lieu of an abstract, here is a brief excerpt of the content:Aristotle on the Etruscan Robbers:A Core Text of "Aristotelian Dualism"Abraham P. Bos (bio)1. A Non-Platonic Dualism in Aristotle's Lost WorksThe Soul of a Mortal on Earth is not "At Home," says Aristotle in his dialogue Eudemus. The story about the mantic dream of the expatriate Eudemus and his expectation that he "will return home"1 is well known. It makes clear that, in Aristotle's view, the death of the human (...) individual should be interpreted as the soul's "return to its homeland."2 This is strongly suggested by "the revelation of Silenus" which Plutarch (first century CE) passes down in a literal quotation from the Eudemus.3 It contains the theme of human life on earth as a punishment (timôria). The motif of human life as a punishment is central to two texts by Iamblichus (250-325 CE) and Augustine (354-430 CE), which are usually connected with Aristotle's Protrepticus.4 I want to examine these texts in more detail here. My intention in the following exposition is to propose a non-Platonistic explanation of these texts. In my opinion they have wrongly been read as testimonies of a "Platonistic" phase in Aristotle. The existence of such a phase in Aristotle's development has never been proved. Besides, the interpretation of these texts suffered from the fact that [End Page 289] Aristotle's De anima had also been explained in an unhistorical way since Alexander of Aphrodisias in the third century CE.2. Revising the Modern View of AristotleWe have to make a different assessment of Aristotle's contribution to the discussion on the soul compared with what was current until recently. For after W. Jaeger5 and F. Nuyens6, modern scholars became inclined to leave Aristotle's dialogues out of consideration, because they regarded them as "Platonizing." But a fundamental correction is necessary on this point.7 Jaeger led modern Aristotle studies in a wrong direction by assuming a sharp distinction between Aristotle's lost dialogue Eudemus and his surviving treatise De anima. Although nowadays Jaeger's theory for many scholars is something of a dead horse, nevertheless a real alternative has not been proposed. We still have to get rid of the consequences of the Jaegerian paradigm and develop a unitary interpretation of Aristotle's entire oeuvre. Even more consistently than O. Gigon has already done,8 we should assume that Aristotle's lost works and his surviving biological writings and De anima did not propose two (or more) different psychological theories but one and the same. Because this one Aristotelian psychology was a non-Platonistic but nevertheless dualistic psychology, we have much more reason than could be recognized in the past to assume Aristotelian influence on this discussion.On one essential issue Aristotle disagreed with his teacher Plato: the soul,9 more particularly the indissoluble bond of the soul with a body. Aristotle radically and [End Page 290] consistently argued for the distinction between nous and psychè.10 For Aristotle the nous-in-act is always wholly incorporeal. But he considered it characteristic of the soul that it cannot carry out its functions "without body."11However, the crucial question is: what body does Aristotle mean when he says that the soul cannot perform its specific activities "without body"? Jaeger and Nuyens were wholly convinced that Aristotle was referring to the visible, external body of a human being, animal, or plant. Hence they saw a yawning gap between Aristotle's views in De anima and his position in the dialogue the Eudemus. In the Eudemus Aristotle had clearly argued that the soul can perform its own functions very well, indeed better, without the galling and oppressive visible body.12 But in De anima II 1, in his famous definition of "the soul," Aristotle says that the soul is inextricably bound up with a "sôma physikon organikon."13 Jaeger and Nuyens, following an almost unanimous tradition since Alexander of Aphrodisias in the third century CE, interpreted this sentence in the sense that the soul is the formal principle or entelechy of an "organic body" or a "natural body equipped with organs," i.e., the visible body...

The criminal law presently distinguishes between actions and omissions, and only rarely proscribes failures to avert consequences that it would be an offense to bring about. Why? In recent years it has been persuasively argued by both Glover and Bennett that, celeris paribus, omissions to prevent a harm are just as culpable as are actions which bring that harm about. On the other hand, and acknowledging that hitherto “lawyers have not been very successful in finding a rationale for it,” Tony (...) Honoré has sought to defend the law's differential treatment. He proposes a “distinct-duties theory” that in addition to the general duties we owe to everyone, we also owe distinct duties to a more limited collection of people and associations, specified by features of our relationship with them. Where a distinct duty holds, breach by omission may well be no better than breach by positive action. But absent a distinct duty, omissions, per Honoré, are less culpable. They are mere failures to intervene and improve or rectify things, whereas actions are positive interventions which make things worse. And, thus, the law has good reason to differentiate between them. (shrink)

In 1956, a few writings of Wittgenstein that he didn't publish in his lifetime were revealed to the public. These writings were gathered in the book Remarks on the Foundations of Mathematics (1956). There, we can see that Wittgenstein had some discontentment with the way philosophers, logicians, and mathematicians were thinking about paradoxes, and he even registered a few polemic reasons to not accept Gödel’s incompleteness theorems.

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

Relativistic quantum mechanics has been formulated as a theory of the evolution ofevents in spacetime; the wave functions are square-integrable functions on the four-dimensional spacetime, parametrized by a universal invariant world time τ. The representation of states with spin is induced with a little group that is the subgroup of O(3, 1) leaving invariant a timelike vector nμ; a positive definite invariant scalar product, for which matrix elements of tensor operators are covariant, emerges from this construction. In a previous study (...) a second-order equation was introduced similar to the second-order Dirac equation, based on a quadratic function of two operators which are the self-adjoint parts, in this new scalar product, of γμpμ. It is shown in this paper that one of these operators, in fact the one from which the gyromagnetic moment is obtained, can be used to construct a first-order equation. The corresponding quantum theory is somewhat analogous to Dirac's spinor form; the Hamilton equations appear to describe dynamical degrees of freedom in a spacelike hyperplane orthogonal to nμ (in Dirac's theory the motion appears to be lightlike). It is shown that the integration over nμ required by unitarity results in timelike motion (as in the expectation value of Dirac's α). Explicit forms are obtained for the wave functions and currents for free motion. The general form of the theory is written for the (five-dimensional) pre-Maxwell fields required by gauge invariance.

In 1992, Law and Philosophy published an account of the paradigm case of intended action; one which gestured at, and did not pursue, an explanation of the requirement that a person be an agent in respect of her behaviour before that behaviour can constitute intended action. This paper completes that account by supplying an analysis of agency. The paper falls into three parts. It begins by casting doubt upon the possibility of specifying a causal account along the lines once envisaged (...) by Davidson. An alternative approach is adopted: one that involves modifications to Frankfurt's depiction of action as behaviour under the agent's guidance, including a rejection of the view held by many writers that action requires intentional movement. Doubts about conventional wisdoms are also raised in the conclusion, which considers why philosophers and lawyers should be interested in the issue of agency at all. (shrink)

In a recent article on the Vettius affair Professor Lily Ross Taylor has tried to show that this letter should be dated to mid-July 59, and that it is therefore antecedent to 2. 20, 21, and 22. According to the hitherto accepted view the letters 2. According to the hitherto accepted view the letters 2. 18–25 are given by the manuscripts in the right chronological order, and since 21 is certainly later than Pompey's contio on 25 July , 23 and (...) 24 must fall later in the year; a terminus ante quem for the description of the Vettius affair in 24 is to be found in in Vat. 25, which shows that L. Lentulus, one of the persons Vettius implicated, was then a candidate for the consulship and that the letter is therefore antecedent to the consular elections, postponed by Bibulus' edict to 18 October . The purpose of this note is to defend this view and show that Professor Taylor's new dating is wrong. (shrink)
