This book draws on fields as diverse as biochemistry, physiology, pharmacology, psychology, psychiatry, and ethology, to form a fascinating synthesis of information on the nature of fear and of panic and anxiety disorders. Dr. Marks offers both a detailed discussion of the clinical aspects of fear-related syndromes and a broad exploration of the sources and mechanisms of fear and defensive behavior. Dealing first with normal fear, he establishes a firm, scientific basis for understanding it. He then presents a thorough analysis (...) of the development, symptoms and treatment of fear-related syndromes. Phobic and obsessive-compulsive disorders are examined in detail. The book is illustrated with examples of fear and defensive behavior in other living organisms. By drawing provocative analogies between animal and human behavior, it sheds new light on the origins of fears, phobias, and obsessive-compulsive problems, as well as on their treatment by drugs and psychological means. Clinical psychologists, ethologists, and anyone interested in the mechanisms of behavior will be fascinated by this authoritative study. The text is intriguing and informative, and the bibliography of over 2,100 entries makes it an invaluable reference. (shrink)

Once upon a time, modal logic was castigated because it ‘had no semantics.’ Kripke, Hintikka, Kanger, and others changed all that. In a similar way, when Relevant Logic was introduced by Anderson and Belnap, it too was castigated for ‘having no semantics.’ The present overview marks a culmination of that effort. The semantic approach described here brings together a number of hitherto disparate efforts to set out formal systems for logics of relevant implication and entailment. It also makes clear (despite (...) some of our hopes and utterances) that the One True Logic does not exist. This is as true for relevant logics as Kripke et al., showed it to be for modal logics. In both cases, subtle (and not so subtle) variations on semantical postulates produce different logics in the same family. The question of which semantical postulates are correct makes no sense without further context, i.e., the questioner needs to answer the question: Correct for what? The question that does remain is: What motivates the relevant family of logics? And this is the question that is the main job for this chapter to investigate. (shrink)

The Logic R4 is obtained by adding the axiom □ → to the modal relevant logic NR. We produce a model theory for this logic and show completeness. We also show that there is a natural embedding of a Kripke model for S4 in each R4 model structure.

This Handbook defines, illustrates, and challenges the field of environmental political theory. Through a broad range of approaches, it shows how scholars have used concepts, methods, and arguments from political theory and closely related disciplines to address contemporary environmental problems. Topics include the relationship of EPT to traditions of political thought; EPT conceptualizations of nature, the environment, community, justice, responsibility, rights, and flourishing; explorations of the structures that constrain or enable the achievement of environmental ends; and analyses of methods for (...) fostering environmental change.

Cet article débute par quelques brèves considérations sur la notion même de l'économie dirigée et sur les limitations inévitables d'une économie dirigée du type capitaliste. Les auteurs cherchent ensuite à démontrer que dans les conditions actuelles une économie dirigée socialiste est parfaitement possible au point de vue économique. Ils étudient les principaux types d'essais de solutions, différenciant entre les deux types fondamentaux („Verwaltungssozialismus“ et „Marktsozialismus“) ainsi que pour chaque type entre les formes pures et les formes modifiées. Il n'y a (...) pas d'opposition irréductible entre ces deux types ; T article montre au contraire F existence de relations entre eux. Dans une exposition objective des problèmes essentiels, il examine en détail la question de savoir si et comment on peut établir des calculs économiques dans les différentes conditions et assurer un développement sans crises deFéconomie. L’analyse est complétée par des recherches sur la productivité d’une économie dirigée socialiste et sur les principes de l’intégration de l’individu, en tant que consommateur et bénéficiaire de revenus, dans l’économie planée. Il résulte de l’étude que les objections de principe soulevées par la critique libérale ne se justifient aucunement. Les différences existant entre les divers types sont purement de nature „technique“, et les véritables oppositions dans la théorie du socialisme ne résident pas du tout dans le mode d’organisation de l’économie dirigée, mais dans les conditions sociologiques et politiques préalables. Pour terminer, les auteurs critiquent sévèrement l’introduction dans le socialisme d’un „secteur d’économie privée“.After a short exposition of the concept of economic planning, and of the definite limits to capitalist planning, it is shown how on the basis of present-day suppositions, socialist planning is economically possible. A typology of the most important solutions offered distinguishes between „administrative“ and „market“ socialism, and between the pure and modified forms in both types. Between these two main types there does not exist an opposition that cannot be bridged — indeed passages of contact run from one to the other. A positive analysis of the main problems offered in reply to a criticism treats in detail of the problem of whether and how under several suppositions we can economically calcutate and ensure a planned economic society free from crises. There then follow investigations into the productivity of a socialistically planned society, and into the principles governing individuals as consumers and income receivers in the totality of economic life. It is seen that the basic objections raised by liberal criticism do not meet the case. The differences between the types are only of a technical nature. The essential antitheses in the theory of socialism is not to be sought in the kind of organization of the planned economy, but in fundamental sociopolitical suppositions. Finally concessions towards a private economy section under socialism receive a thorough criticism. (shrink)

A perennial question in the philosophy of time concerns the relation between the objective “physical time” that features in empirical theories of motion and the subjective “human time” in which our own experiences unfold. This article is about one facet of this broader question: whether the phenomenon of consciousness allows us to make a principled distinction between the present and other times. A number of authors have argued that, without conscious observers, there would be no distinctions of past, present, and (...) future. This paper defends the opposing thesis that there is no interesting connection between consciousness and presentness. (shrink)

In this chapter, we consider the relationships between democracy, equality, and justice and the ways in which those relationships define the territory of contemporary political philosophy.

Business students are taught only technical knowledge without concern for holistic engagement; the reputation of business managers is declining due to their disregard for acting ethically. This graduate textbook introduces a business ethics from the.
