_The Sceptics_ is the first comprehensive, up-to-date treatment of Greek scepticism, from the beginnings of epistemology with Xenophanes, to the final full development of Pyrrhonism as presented in the work of Sextus Empiricus. Tracing the evolution of scepticism from 500 B.C to A.D 200, this clear and rigorous analysis presents the arguments of the Greek sceptics in their historical context and provides an in-depth study of the various strands of the sceptical tradition.

In this paper I argue that human pattern recognition can be simulated by automata. In particular, I show that gestalt recognition and recognition of family resemblances are within the capabilities of sufficiently complex Turing machines. The argument rests on elementary facts of automata and computability theory which are used to explicate our preanalytic, informal concepts concerning gestalt patterns and recognition. The central idea is that of a machine which "knows" its own structure. Although the paper thus aims to support mechanism, (...) especially as a framework hypothesis for perception, it contains suggestions for philosophy of science and philosophy of language as well. Some of these suggestions are sketched in the final section. (shrink)

In the Archaic Geek world of epic poetry, the causes of things are shrouded in divine mystery; the gods intervene in human affairs, and bring about events, in a cruel and capricious fashion, according to their whims; Apollo visits the devastating plague of Iliad 1 on the Greek host to avenge Agamemnon's ill-treatment of one of his priests; Poseidon shakes the earth and angers the sea, bringing to destruction those who have incurred his ire, as does Zeus himself with his (...) thunderbolts. The gods take on human shape and intervene in battle with devastating effect. In tragedy, the houses of Atreus and of Laius are brought low when men offend against the gods. This article focuses on the explorations of the fundamental concepts of reasons and causation, and the problems of explanation, and argues that it is indeed reasonable to see in Presocratic thought the foundations of Western scientific explanation.

Spinoza's concept of ?power? finds expression in every major topic of which he treats. Some of the ways to the understanding of that concept are: the metaphysical, the genetic, and the political. I. Metaphysically, Spinoza distinguishes power from force or energy and defines it as the ability of a system to survive. The most interesting application of this definition is to that system, man, for whom survival means realization of his essence, achievement of understanding. II. The depth and generality of (...) Spinoza's concept of power can be appreciated more clearly if we refer to its sources in (1) the classical analysis of ?virtue? beginning with Plato, (2) the traditional theological ponderings on the nature of God, and (3) the method and presuppositions of physical science. III. At the metaphysical level of analysis, power and liberty are shown to be all but synonymous. Spinoza's analysis of political power undermines previous authoritarian, hierarchical, and elitist theories of government and ends with a proof that both individual and social power flourish best under democratic government.

As the above quote clearly highlights, it is the responsibility of researchers and research supervisors to be certain that their research staff and students assistants are very familiar with all of the ethical principles and current standards relevant to the research they are conducting. Indeed, they must take an active role in being certain that their research staff and students complete appropriate training in these ethical principles and standards, and how they apply them to the research context in which they (...) are working. This is especially important in areas in which there may be physical harm such as chronic pain research. (shrink)

Patients who are dying of cancer usually give up eating and then stop drinking. This raises ethical dilemmas about providing nutritional support and fluid replacement. The decision-making process should be based on a knowledge of the risks and benefits of giving or withholding treatments. There is no clear evidence that increased nutritional support or fluid therapy alters comfort, mental status or survival of patients who are dying. Rarely, subcutaneous fluid administration in the dying patient may be justified if the family (...) remain distressed despite due consideration of the lack of medical benefit versus the risks. Some cancer patients who are not imminently dying become dehydrated from reversible conditions such as hypercalcaemia. This may mimic the effects of advanced cancer. These conditions should be sought and fluid replacement therapy should be given along with the specific treatments for the condition. (shrink)

To examine to what degree argumentation skills are mastered by pupils who attend the vocational, general and academic streams in Dutch secondary education various subtests were constructed. The theoretical study of argumentation as exposed by Van Eemeren and Grootendorst was the basis for this test construction. In this article tests for the identification of singular, multiple and subordinate argumentation are described. Also an account is given of a pretest of these three subtests.

The traditional view was that a concept must be immediate if anything is, i.e., it must be something possessed directly by my mind. To deny this seems to be saying "I think but I don't have ideas." This is of course what the proponents of the linguistic philosophy are in effect saying, and perhaps for them it is all right. Professor Price has argued ingeniously against the whole linguistic position: against the possibility of a purely linguistic solution to the problem. (...) Yet whether we follow Price or the language philosophers we are forced into a rather puzzling situation. One likes to say that one has ideas, thoughts, concepts, but there is a serious question as to whether we can ever actually cognize such entities. Indeed Price introspects and does not find them. Most of us--including our linguistic colleagues--would be quick to agree. A thought cannot be introspected like an image. There just does not seem to be anything there. As thinkers of thoughts, we are looking inward toward nothing; we are indeed living examples of "hollow men." So it is that we are faced with a dilemma. Either we say we think but do not really have ideas, or we must somehow show that such concepts are actually immediate after all. Neither alternative seems the least bit welcome. The latter seems utterly impossible. (shrink)

One cannot but notice Plato's interest in prophecy and divination. He speaks disparagingly of the art and of those who practised it, yet it seems to have held some fascination for him. Moreover, he frequently uses the language of prophecy in a metaphorical sense, and it is this which I am to examine. Often, of course, this use is facetious, especially with the nouns ‘prophet’ and ‘prophecy’: he is ridiculing obscurity or playfully lending dignity to an obvious inference. But I (...) suggest that this facetious usage is common enough to be in itself evidence for the familiarity of Plato with this way of thinking. (shrink)

This paper uses the case of solo doctors to explore whether working in relative isolation from one’s peers may be detrimental to ethical decision-making. Drawing upon the relevance of communication and interaction for ethical decision-making in the ethical theories of Habermas, Mead and Gadamer, it is argued that doctors benefit from ethical discussion with their peers and that solo practice may make this more difficult. The paper identifies a paucity of empirical research related to solo practice and ethics but draws (...) upon more general medical ethics research and a study that identified ethical isolation among community pharmacists to support the theoretical claims made. The paper concludes by using the literary analogy of Soderberg’s Doctor Glas to illustrate the issues raised and how ethical decision-making in relative isolation may be problematical. (shrink)

In 'A Note on “Scepticism and Absurdity”; ' (Inquiry, Vol. 10 [1967], No. 3), Zinkernagel has restated his attack on scepticism, maintaining that his approach, where we need only refer to a simple and inspectable fact of language, offers a decisive argument against scepticism. It is suggested that Zinkernagel's optimism is unwarranted because on close inspection his general theory reveals some serious complexities, and it is shown that in his own terms Zinkernagel's second rule is not a condition for description.

In this chapter, Hankinson discusses Aristotle's conceptions of nature, change, and potentiality; the four causes, spontaneity, and chance; teleology and hypothetical necessity; and also Aristotle's account of action, freedom, and responsibility. The choice facing Greek philosopher‐scientists is simple: show how a structured, regular world could arise out of undirected processes, or pursue a teleological explanation, insisting on the activity of divine intelligence in the cosmos. Aristotle, Hankinson writes, pursues a middle way between these options, although, ultimately, Aristotle takes the whole (...) structure of the cosmos to be teleologically organized. Aristotle rejects Plato's metaphysics of perfect hypostasized forms and divinely directed teleology: relying heavily on his concept of phusis or nature, Aristotle makes teleology an internal principle governing the development of natural objects. Aristotle distinguishes four causes or causal factors in explanation: matter, form, agent, and end, and he distinguishes sharply between regular natural events that can be explained by means of these causes, and chance events, which do not admit full explanation.

In this chapter, Hankinson discusses the major Hellenistic Medical theories and figures, from the Alexandrian doctors Herophilus and Erasistratus in the third century bc to the Empiricist, Rationalist, and Methodist schools of the early Imperial period. Hankinson argues that the practical basis of medical science broadened and deepened the debate about the nature of causal explanation. The Empiricists were sceptics in their attitude to causes, thinking that observation and report of evident conditions and their cures was sufficient for medical science, (...) and thus eschewing causal theory. Rationalist doctors attacked the inadequate methodology of the Empiricists, and they try to explain why the antecedent cause should bring on such and such an effect, while emphasizing the need to decide rationally the proper use of induction, and the relevancy of similarities. The Methodists treat as irrelevant antecedent causes or factors, and they recognized just two pathological conditions—relaxation and constriction; the doctor's concern is to determine by direct observation in which state is the body.
