"Put together one of the world's best science writers with one of the universe's most fascinating subjects and you are bound to produce a wonderful book.... The subject of complexity is vital and controversial. This book is important and beautifully done."--Stephen Jay Gould "[Complexity] is that curious mix of complication and organization that we find throughout the natural and human worlds: the workings of a cell, the structure of the brain, the behavior of the stock market, the shifts of political (...) power.... It is time science... thinks about meaning as well as counting information.... This is the core of the complexity manifesto. Read it, think about it... but don't ignore it."--Ian Stewart, "Nature" This second edition has been brought up to date with an essay entitled "On the Edge in the Business World" and an interview with John Holland, author of "Emergence: From Chaos to Order.".

From Thomas Hobbes to Jeremy Bentham, 'British Moralists' have questioned whether being virtuous makes you happy. Roger Crisp elucidaties their views on happiness and virtue, self-interest and sacrifice, and well-being and morality, and highlights key themes such as psychological egoism, evaluative hedonism, and moral reason in their thought.

It is often supposed that in order to refute the view that laws of nature are necessary truths it is sufficient to appeal to Hume's argument from the conceivability of to the possibility of their being false. But while Hume's argument does present the necessitarian with insuperable difficulties it needs to be made clear just what these are. The mere appeal to Hume is quite insufficient for what he says can be interpreted in more than one way. And if it (...) constitutes an argument rather than a mere assertion Kneale has given reason to suppose that it is at least not obviously valid. The upshot of this article is that Hume's argument may be seen as a direct challenge to the notion that there could be propositions whose modal value is necessarily "opaque to the human intellect".

Gottfried Wilhelm Leibniz (1646-1716) was one of the seventeenth century's most important thinkers. A philosopher, mathematician and scientist, his work is comparable in scope and importance only to that of Newton and Descartes. His work dominated German philosophy until Kant, and was revived in the early part of this century when his important work on logic was re-discovered. This four volume set contains 97 of the most important essays ever written about Leibniz's work. The selection has been made to bring (...) out the scope of Leibniz's work in all the areas he wrote upon, as well as its importance to contemporary philosophy and the history of philosophy. It will be an essential reference work for anyone concerned with seventeenth century philosophy and science, as well as to all Leibniz specialists. (shrink)

This is the text of the Lindley Lecture for 2018 given by Roger Crisp, a Professor of Moral Philosophy at St. Anne’s College, Oxford.

I argue that Descartes and the Cartesians are likely in agreement that logic is an ars cogitandi whose aim is to perfect the ingenium by the exercise of its operations: ideating, judging, discoursing, and ordering. We can see that these elements are the underpinning of both the Regulae and the Discourse on Method, and thus, like Adrien Baillet and others in the seventeenth century, we can understand these two works as embodying Descartes’ “logic,” despite Descartes’ notorious anti-logic Renaissance rhetoric in (...) both writings.

Philosophers have turned their attention in recent years to many previously unmined topics, among them love and friendship. In this collection of new essays in philosophical and moral psychology, philosophers turn their analytic tools to a topic perhaps most resistant to reasoned analysis: erotic love. Also included is one previously published paper by Martha Nussbaum.Among the problems discussed are the role that qualities of the beloved play in love, the so-called union theory of love, intentionality and autonomy in love, and (...) traditional issues surrounding jealousy and morality.

A brief, radical defense of human uniqueness from acclaimed philosopher Roger Scruton In this short book, acclaimed writer and philosopher Roger Scruton presents an original and radical defense of human uniqueness. Confronting the views of evolutionary psychologists, utilitarian moralists, and philosophical materialists such as Richard Dawkins and Daniel Dennett, Scruton argues that human beings cannot be understood simply as biological objects. We are not only human animals; we are also persons, in essential relation with other persons, and bound (...) to them by obligations and rights. Our world is a shared world, exhibiting freedom, value, and accountability, and to understand it we must address other people face to face and I to I. Scruton develops and defends his account of human nature by ranging widely across intellectual history, from Plato and Averroës to Darwin and Wittgenstein. The book begins with Kant's suggestion that we are distinguished by our ability to say "I"—by our sense of ourselves as the centers of self-conscious reflection. This fact is manifested in our emotions, interests, and relations. It is the foundation of the moral sense, as well as of the aesthetic and religious conceptions through which we shape the human world and endow it with meaning. And it lies outside the scope of modern materialist philosophy, even though it is a natural and not a supernatural fact. Ultimately, Scruton offers a new way of understanding how self-consciousness affects the question of how we should live. The result is a rich view of human nature that challenges some of today's most fashionable ideas about our species. (shrink)

We examine Duhem's critique of Maxwell, especially Duhem's complaints that Maxwell's theory is too bold or not systematic enough, that it is too dependent on models, and that its concepts are not continuous with those of the past. We argue that these complaints are connected by Duhem's historical criterion for the evaluation of physical theories. We briefly compare Duhem's criterion of historical continuity with similar criteria developed by "historicists" like Kuhn and Lakatos. We argue that Duhem's rejection of theoretical pluralism (...) was a primary factor preventing him from recognizing Maxwell's work as an autonomous tradition. (shrink)

Among other interesting proposals, Juan Comesaña’s _Being Rational and Being Right_ makes a challenging case that one’s evidence can include falsehoods. I explore some ways in which we might have to rethink the roles that evidence can play in inquiry if we accept this claim. It turns out that Comesaña’s position lends itself to the conclusion that while false evidence is possible and not even terribly uncommon, I can be rationally sure that I don’t currently have any and perhaps also (...) that I won’t get any, and (absent certain evidence to the contrary) you are not afflicted with any either. This conclusion might seem too good to be true. I finish by raising a puzzle about one of the main motivations for Comesaña’s view. (shrink)

Objectives – To propose a neuropsychological study of the various aspects of self-consciousness (SC) in Alzheimer’s disease. Methods – Forty-five patients with probable mild or moderate AD were included in the study. Severity of their dementia was assessed by the Mini Mental State (MMS). Fourteen questions were prepared to evaluate SC. Results – No (...) significant correlations were found between SC score and educational level, age, and duration of disease. A significant correlation was found between SC score and the severity of dementia, whereas frontal disturbances were just short of the significance threshold. The various aspects of SC were not impaired to the same degree. The most disturbed ones were awareness of cognitive deficiencies, moral judgements and prospective memory. The least disturbed aspects were awareness of identity and of mental representation of the body. Items relating to anosognosia and moral judgements were significantly correlated with the MMS score, whereas affective state, body representation disorders, prospective memory, and capacities for introspection were not related to the severity of the dementia. Consciousness of identity was sound, regardless of MMS score. Conclusions – AD clearly induces an heterogeneous impairment of SC. SC requires a convergence of many neural networks. In AD, neuronal alterations involve many cortical areas and information sent to the associative frontal cortex from memory, language and visuospatial areas is lacking or disturbed. Thus, the sequential order of successive stimuli cannot be maintained by the heteromodal associative cortex (dorsal convexity of the prefrontal cortex), and the supramodal associative cortex (located rostrally in the frontal lobes) is unable to provide reliable monitoring and assessment of simultaneous neural cognitive networks carrying insufficient and inadequate input. The core deficiency in AD patients might be impaired SC equated with the disability to maintain sequential and simultaneous ‘‘attention to life’’. The Self-Consciousness Questionnaire, a clinical scale providing multidimensional measurement, indicates that different aspects of consciousness are not correlated with overall cognitive deficiency as determined by the MMSE.

Conjecture (1) of [Ma83] is confirmed here by the following result: if $3 \leq \alpha < \omega$, then there is a finite relation algebra of dimension α, which is not a relation algebra of dimension α + 1. A logical consequence of this theorem is that for every finite α ≥ 3 there is a formula of the form $S \subseteq T$ (asserting that one binary relation is included in another), which is provable with α + 1 variables, but not (...) provable with only α variables (using a special sequent calculus designed for deducing properties of binary relations).

Health professionals do not always have the luxury of making “right” choices. This article introduces the “devil's choice” as a metaphor to describe medical choices that arise in circumstances where all the available options are both unwanted and perverse. Using the devil's choice, the paper criticizes the principle of double effect and provides a re-interpretation of the conventional legal and ethical account of symptom relief in palliative care.

The work of the later Wittgenstein has had a vast influence in the field of social science. This is hardly surprising as the effect of that philosophy has been an emphasis on the priority of the social. Empiricist philosophy started with the private experience of the individual and from there built up an inter-subjective picture of the world. Wittgenstein, on the other hand, began with the rule-governed practices of a community. Both the nature of private experience, and of an objective (...) world, was deemed to depend on concepts all could share. Society is the source of such concepts and thus becomes the key notion in our understanding of ourselves and our relation to the world. (shrink)

. Prospects for uniting religion and science are brightened by recently changed views of consciousness and mind‐brain interaction. Mental, vital, and spiritual forces, long excluded and denounced by materialist philosophy, are reinstated in nonmystical form. A revised scientific cosmology emerges in which reductive materialist interpretations emphasizing causal control from below upward are replaced by revised concepts that emphasize the reciprocal control exerted by higher emergent forces from above downward. Scientific views of ourselves and the world and the kinds of values (...) upheld by scientific belief undergo basic transformations, making them more compatible with religious motivation and moral responsibility.

The Platonic view that art is incapable of providing us with knowledge is sufficiently widely held as to merit a serious attempt at refutation. Once it is acknowledged that there are alternative forms of knowledge other than propositional, then it is possible to establish the truth of the claim that the knowledge which art affords has a value on a par with that provided by other disciplines. Art, it is argued, has a unique potential to provide imaginative insights by reference (...) to which we may understand what it is like to experience and to feel, in ways very different from those with which we may be familiar. It is shown to be instrumental in enabling us to refine our moral concepts as well as in determining what is salient from the moral point of view. As a powerful tool in the education of the emotions, artworks have the power to increase our moral sensitivity and to sharpen our perception of what is required of us inways that are otherwise unobtainable.

Distinguished scholars discuss the problem of self-deception, or rather, self and deception.

In Death-Devoted Heart Roger Scruton argues that Tristan und Isolde has profound religious meaning. Blending philosophy, criticism and musicology, he shows the work is as relevant today as it was to Wagner's contemporaries. Scruton's analysis touches on the nature of tragedy, the significance of ritual sacrifice, and the meaning of redemption.

This paper grew out of a reaction to Elisabeth Selkirk's contribution to the Handbook of Phonology (Goldsmith 1996). Section 1.2 of that article is concerned with syntactic and semantic aspects of the placement of pitch accents in English. As will be seen in the data to be presented below, the constellation of pitch accents in an utterance is determined in part by properties of the preceding discourse, including the distinction between new and old information. This means for example, that a (...) phrase containing accent is appropriate in a different set of contexts than that same phrase unaccented. Since accents are assigned within words but the pragmatics can make reference to phrases, the following question arises. Given a word that is accented, which phrases count as containing accent as far as the pragmatics is concerned and which not? This question is known as the projection problem, though I have characterized it in slightly different terms than is normally done, for reasons to be made clear below. As Selkirk shows, projection is sensitive to argument structure and other syntactic notions (see Gussenhoven(1984), Rochement(1986), Schmerling(1976) and Selkirk 1984)). In Selkirk's system, a sentence can have one or more foci and these foci are marked with an F in the syntactic tree. Focussing a phrase leads to a certain kind of.. (shrink)

SubStance is pleased to present, for the first time in English, the Prologue and Epilogue from Roger Caillois's Pierres réfléchies. Pierres réfléchies is the last, and least cited, of Caillois's singular writings on stones, which are being rediscovered and reread in the contemporary geologic-philosophical-aesthetic context. Here, Caillois provides a final articulation of his mystical materialism and diagonal science, his hermetic reading of a cosmos composed of hieroglyphic signs, in which "stone… speaks… the most convincing language in the universe." These (...) ruminations from Pierres réfléchies display a deeper methodological discernment, and more somber humor, than the earlier works. Perhaps this is... (shrink)

There is a class of speech-acts employing expressions such as ‘can't, ‘must’, and ‘meant to’, which have a paradigm role in stating the rules that govern a practice. Elizabeth Anscombe called such expressions stopping (or forcing) modals. Although “You can't phi”, etc., are not implicit hypothetical imperatives, it nevertheless makes prima facie sense to ask of a given practice why we go in for it, what the point of it is. Various questions are discussed in connection with these facts, e.g. (...) What distinguishes a rule's applying to someone from its having force (for that person)? Where the practice at issue is a ‘language-game’, does the question “Why do we do this?” still makes sense? (shrink)

This study explores how the integration of environmental practices in gastronomic tourism can increase the competitiveness of tourist destinations in Latin America. Through the analysis of cases in Mexico, Peru and Colombia, sustainable strategies are identified, such as the use of local products and the reduction of waste, which not only contribute to sustainable tourism development, but also improve the image and attractiveness of destinations. The results show that destinations that implement sustainable environmental practices are perceived as more attractive and (...) competitive in a tourism market that is increasingly aware of ecological impacts.
