The belief that Aristotle opposes potency (dunamis) to actuality (energeia or entelecheia) has gone untested. This essay defines and distinguishes forms of the Opposition Hypothesis—the Actualization, Privation, and Modal—examining the texts and arguments adduced to support them. Using Aristotle’s own account of opposition, the texts appear instead to show that potency and actuality are compatible, while arguments for their opposition produce intractable problems. Notably, Aristotle’s refutation of the Megarian Identity Hypothesis applies with equal or greater force to the Opposition Hypothesis. (...) For Aristotle, then, potency and actuality are compatible.

Jeffrey Friedman credits Popper for calling attention to our scientific ignorance, but faults him for failing to recognize that we are at least as ignorant about politics as we are about science. He also credits Hayek for realizing that the public could not successfully engage in piecemeal economic regulation, but faults him for not recognizing that this is due to the public's ignorance of economic theory. Friedman suggests that the types of ignorance overlooked by Popper and Hayek compromise the very (...) possibility of democracy—or at least social democracy. He assumes, however, that the success of social democracy and “piecemeal social engineering” depend upon their ability to produce “good” policies. This does not do justice to Popper's views about democracy and piecemeal engineering, and it also presumes an underlying economism that Popper criticized—but to which Friedman and Hayek adhere.

For more than a quarter of a century, Hubert L. Dreyfus has been the leading voice in American philosophy for the continuing relevance of phenomenology, particularly as developed by Edmund Husserl, Martin Heidegger, and Maurice Merleau-Ponty. Dreyfus has influenced a generation of students and a wide range of colleagues, and these volumes are an excellent representation of the extent and depth of that influence.In keeping with Dreyfus's openness to others' ideas, many of the essays in this volume take the form (...) of arguments with various of his positions. The essays focus on the dialogue with the continental philosophical tradition, in particular the work of Heidegger, that has played a foundational role in Dreyfus's thinking. The sections are Philosophy and Authenticity; Modernity, Self, and the World; and Heideggerian Encounters. The book concludes with Dreyfus's responses to the essays.Contributors : William D.

Weak emergence has been offered as an explication of the ubiquitous notion of emergence used in complexity science (Bedau 1997). After outlining the problem of emergence and comparing weak emergence with the two other main objectivist approaches to emergence, this paper explains a version of weak emergence and illustrates it with cellular automata. Then it explains the sort of downward causation and explanatory autonomy involved in weak emergence.

Weak emergence is the view that a system’s macro properties can be explained by its micro properties but only in an especially complicated way. This paper explains a version of weak emergence based on the notion of explanatory incompressibility and “crawling the causal web.” Then it examines three reasons why weak emergence might be thought to be just in the mind. The first reason is based on contrasting mere epistemological emergence with a form of ontological emergence that involves irreducible downward (...) causation. The second reason is based on the idea that attributions of emergence are always a reflection of our ignorance of non-emergent explanations. The third reason is based on the charge that complex explanations are anthropocentric. Rather than being just in the mind, weak emergence is seen to involve a distinctive kind of complex, macro-pattern in the mind-independent objective micro-causal structure that exists in nature. The paper ends by addressing two further questions. One concerns whether weak emergence applies only or mainly to computer simulations and computational systems. The other concerns the respect in which weak emergence is dynamic rather than static. (shrink)
