O livro almeja ser representativo nos principais debates contemporâneos, oferecendo uma visão panorâmica sobre o campo na atualidade e permitindo-se aprofundar em algumas discussões selecionadas.O ambiente não pode ser reduzido ao “meio ambiente”, à natureza não humana. Ele não é meramente algo que “nos envolve”, um envoltório: o ambiente somos também nós, seres humanos, histórica e culturalmente situados. Quanto aos territórios, eles se estabelecem em íntima conexão com os ambientes em suas dimensões paisagística e material, quer sejam os processos geoecológicos, (...) quer sejam as formas e as dinâmicas socialmente produzidas. Analisar os territórios significa examinar como, a cada momento, os ambientes, seus recursos e significados são disputados e viram objeto de conflitos.O público-alvo principal são os estudantes dos últimos anos da graduação, além daqueles em nível de pós-graduação, de todas as áreas que lidam com problemas e conflitos ambientais. Afora os pesquisadores iniciantes e os jovens universitários em geral, porém, podemos presumir que profissionais experientes também poderão tirar proveito do material de diversos capítulos. É razoável, por fim, nutrir a expectativa de que muito do que este livro contém possa (retro)alimentar o ativismo ambiental crítico e a prática de combater as iniquidades e as distorções que se acumulam em nossas sociedades, principalmente as muitas situações de flagrante injustiça ambiental.

Originally published in Proceedings of the British Academy 60 (1974), 339-359.

The idea of a 'logic of quantum mechanics' or quantum logic was originally suggested by Birkhoff and von Neumann in their pioneering paper [1936]. Since that time there has been much argument about whether, or in what sense, quantum 'logic' can be actually considered a true logic (see, e.g. Bell and Hallett [1982], Dummett [1976], Gardner [1971]) and, if so, how it is to be distinguished from classical logic. In this paper I put forward a simple and natural semantical framework (...) for quantum logic which reveals its difference from classical logic in a strikingly intuitive way, viz. through the fact that quantum logic admits (suitably formulated versions of) the characteristic quantum-mechanical notions of superposition and incompatibility of attributes. That is, precisely the features that distinguish quantum from classical physics also serve, within this framework, to distinguish quantum from classical logic. Some light is shed on the question of whether quantum logic is a genuine logical system by introducing a natural entailment relation for quantum-logical formulas with the implication symbol. The novelty is that, although implication behaves as it should (i.e. the 'deduction theorem' holds), the order of introduction of premises is significant. The fact that a reasonable entailment relation can be formulated for quantum logic supports the view that it is a genuine logical system and not merely an algebraic formalism. (shrink)

The paper defends the thesis that for S to V intentionally is for S to V as (in the way) S intended to. For the normal agent the relevant sort of intention is an intention that one's intention to V generate an instance of one's V-ing along some (usually dimly-conceived) productive path. Such an account allows us to say some actions are intentional to a greater or lesser extent (a desirable option for certain cases of wayward causal chains), preserves the (...) intuitive link between intention and intentionally, and supports the common sense view that the concept of intending is more basic than those of acting with an intention and of acting intentionally. The remainder of the paper responds to certain apparent counter-examples offered by Audi, Harman, and Bratman. In the course of this, I discuss connections between intending to V and hoping to V, and I argue that one can intend to do what one doesn't expect to do, and that one always intends what one attempts.

_The Foundations of Arithmetic_ is undoubtedly the best introduction to Frege's thought; it is here that Frege expounds the central notions of his philosophy, subjecting the views of his predecessors and contemporaries to devastating analysis. The book represents the first philosophically sound discussion of the concept of number in Western civilization. It profoundly influenced developments in the philosophy of mathematics and in general ontology.

Criticises G. E. Moore’s highly influential proposal that ascriptions of agent ability implying freedom of choice or action, what the agent could do, are analyzable as conditional statements regarding what the agent would do under certain circumstances. Austin objects against Moore that some uses of ‘if’ are non-conditional and goes on to examine the uses of these non-conditional cases. Moore’s proposal also lies at the heart of some compatibilist theories of free will and determinism. Austin argues determinism to be a (...) pseudo-problem, so long as it remains a notion that is not itself clear cut. (shrink)

This paper argues that, while there is a difference between personal and sub‐personal explanation, claims of autonomy should be treated with scepticism. It distinguishes between horizontal and vertical explanatory relations that might hold between facts at the personal and farts at the sub‐personal level. Noting that many philosophers are prepared to accept vertical explanatory relations between the two levels, I argue for the stronger claim that, in the case of at least three central personal level phenomena, the demands of explanatory (...) adequacy require postulating horizontal explanatory relations.

Austin takes on the problem of other minds, of how to respond to the question ‘how do you know?’, if this question is raised with regard to the thoughts, feelings, sensations, minds of other creatures. This problem has traditionally been understood as the problem of justifying our belief in the existence of other minds. Austin argues that believing in other persons, in authority and testimony, is an essential part of the act of communicating, and as such is an irreducible part (...) of our experience. While we can state certain advantages of communicative performances, there is no justification for our doing them as such. (shrink)

In this paper I discuss a neglected form of argument against religious belief -- generically, 'the probabilistic argument from pluralism'. If the denial of a belief is equivalent to the disjunction of its alternatives, and if we may gain some idea as to the probabilities of such disjunctions by adding the separate probabilities of their mutually exclusive disjuncts, and if, moreover, the denials of many religious beliefs are disjunctions known to have two or more mutually exclusive members each possessing a (...) significant degree or probability, then at any rate in many such cases, the denial of a religious belief can be shown to be more probable than it is -- which is to say that the belief can be shown to be improbable. I consider a large number of responses to arguments of this form, concluding that none suffices to overthrow it altogether. Indeed, the argument remains as a significant threat to any religious belief confronted by a plurality of alternatives. (shrink)

2. The Contingency and A posteriority Constraint: A formulation of the thesis must make physicalism come out contingent and a posteriori. First, physicalism is a contingent truth, if it is a truth. This means that physicalism could have been false, i.e. there are counterfactual worlds in which physicalism is false, for example, counterfactual worlds in which there are miracle -performing angels.[9] Moreover, if physicalism is true, our knowledge of its truth is a posteriori. This is to say that there are (...) ways the world could turn out to be such that physicalism is false. For example, if there are miracle -performing angels, then physicalism is false. So there are worlds considered as actual in which physicalism is false.[10] For short, call this ‘the a posteriority constraint’.[11]. (shrink)

The evolutionary implications of environmental change due to organismic action remain a controversial issue, after a decades—long debate on the subject. Much of this debate has been conducted in qualitative fashion, despite the availability of mathematical models for organism–environment interactions, and for gene frequencies when allele fitness can be related to exploitation of a particular environmental resource. In this article we focus on representative models dealing with niche construction, ecosystem engineering, the Gaia Hypothesis and community interactions of Lotka–Volterra type, and (...) show that their quantitative character helps bring into sharper focus the similarities and differences among their respective theoretical contexts.

In this paper (a sequel to [4]) I put forward a "local" interpretation of mathematical concepts based on notions derived from category theory. The fundamental idea is to abandon the unique absolute universe of sets central to the orthodox set-theoretic account of the foundations of mathematics, replacing it by a plurality of local mathematical frameworks - elementary toposes - defined in category-theoretic terms.

I first sketch an account of humility as a character trait in which we are unimpressed with our good, envied, or admired features, achievements, etc., where these lack significant salience for our image of ourselves, because of the greater prominence of our limitations and flaws. I situate this view among several other recent conceptions of humility (also called modesty), dividing them between the inward-directed and outward-directed, distinguish mine from them, pose problems for each alternative account, and show how my understanding (...) of humility captures truths present but exaggerated in several of them. Responding to some problems for my view, including what I call “Driver’s Paradox”(i.e., the strangeness of someone’s proclaiming ‘I’m humble!’), I suggest that some over-ambitious claims about our moral responsibilities may indicate a lack of proper humility. I discuss the relationship of the character trait of humility both to what humiliates and to what humbles, concluding with consideration of the background assumptions against which, and the circumstances in which, humility may reasonably be classified as a moral virtue.

In this paper I argue that moral virtue is sometimes causally necessary both for theistic belief and for nonbelief. I then argue for some further connectionsbetween these results and the Calvinist view, recently revived in the philosophy of religion, according to which theistic belief is typically warranted and all those who dissent from such belief persist in their nonbelief because of sin. Specifically, I maintain that the virtue of belief militates against its being warranted, and that the virtue of nonbelief (...) renders the Calvinist generalization concerning nonbelief and sin implausible.

This study empirically examines the association between certain director characteristics and the extent of voluntary audit committee disclosure in annual reports. Results suggest that Singapore's publicly traded firms are more likely to voluntarily disclose audit committee related information as: the number of board members increases; different individuals occupy the roles of CEO and board chairperson; and the proportion of independent directors serving on the board increases. Findings, however, fail to show any association between the amount of voluntary audit committee disclosure (...) and the percentage of executive directors' ownership. Documented findings are of interest and benefit to various parties including regulators, corporate governance reformists, and corporate management. For instance, findings imply that a positive by-product of implementing major corporate governance reforms currently championed by corporate governance reformists will be an increase in audit committee disclosures. As a result, there will be less pressure on regulators to develop, introduce, and enforce mandatory audit committee disclosures that may be potentially intrusive to a firm's management. (shrink)

Austin discusses the existence, origin, and resemblance of concepts, primarily by discussing the meaning of ‘concept’ and ‘universal’. He argues that, although sometimes it may not be harmful to talk about concepts, we neither understand the meaning of ‘concept’, nor the meaning of ‘acquiring and possessing concepts’, nor a view of concept resemblance as non-sensuous acquaintance or awareness, challenging philosophers who couch their theories in such terms to illuminating them first.

Addresses Bedford’s attack on appeals to introspection in the identification of emotions, which lead him to raise the question of how to draw the line between genuine and pretended anger. Austin demonstrates, through a close examination of the speech acts of ‘pretending’ and ‘really being’, that none of the supposed conditional relations between these two notions actually holds. The essay further introduces Austin’s distinction between ‘pretending to do’ and ‘pretending to be’ and emphasises the complex and diverse forms speech acts (...) involving ‘pretending’ can take.

A reconstruction based on previously unpublished notes, of Austin’s views of the Line and Cave allegories in Plato’s Republic. In these drafts, Austin discusses the prominent issues that arise in the context of Plato’s Line allegory, e.g. the questions of division and continuity, and shows how the different stages in the Cave allegory correspond to individual sections of the Line.

This essay rebuts Gary Seay's efforts to show that committing euthanasia need not conflict with a physician's professional duties. First, I try to show how his misunderstanding of the correlativity of rights and duties and his discussion of the foundation of moral rights undermine his case. Second, I show aspects of physicians' professional duties that clash with euthanasia, and that attempts to avoid this clash lead to absurdities. For professional duties are best understood as deriving from professional virtues and the (...) commitments and purposes with which the professional as such ought to act, and there is no plausible way in which her death can be seen as advancing the patient's medical welfare. Third, I argue against Prof. Seay's assumption that apparent conflicts among professional duties must be resolved through "balancing" and argue that, while the physician's duty to extend life is continuous with her duty to protect health, any duty to relieve pain is subordinate to these. Finally, I show that what is morally determinative here, as throughout the moral life, is the agent's intention and that Prof. Seay's implicitly preferred consequentialism threatens not only to distort moral thinking but would altogether undermine the medical (and any other) profession and its internal ethics.

Technology has expanded genomic research and the complexity of extracted gene-related information. Health-related genomic incidental findings pose new dilemmas for nurse researchers regarding the ethical application of disclosure to participants. Consequently, informed consent specific to incidental findings is recommended. Critical Social Theory is used as a guide in recognition of the changing meaning of informed consent and to serve as a framework to inform nursing of the ethical application of disclosure consent in genomic nursing research practices.
