Heidegger’s characterization of Dasein as Being-in-the-world suggests a natural relation to environmental philosophy. Among environmentalists, however, closer inspection must raise alarm, both since Heidegger’s approach is in some senses inescapably anthropocentric and since Dasein discovers its environment through its usability, serviceability, and accessibility. Yet Heidegger does not simply adopt a traditionally modern, instrumental view. The conditions under which the environment appears imply neither that the environment consists only of tools, nor that what is true of the parts is also true (...) of the whole, nor that an orientation to use—where appropriate—precludes any other orientation. Heidegger’s anthropocentric commitments thus do not rule out the possibility of a non-instrumental perspective on the natural world. (shrink)

Experimental work has revealed causal links between physical cleansing and various psychological variables. Empirically, how robust are they? Theoretically, how do they operate? Major prevailing accounts focus on morality or disgust, capturing a subset of cleansing effects, but cannot easily handle cleansing effects in non-moral, non-disgusting contexts. Building on grounded views on cognitive processes and known properties of mental procedures, we propose grounded procedures of separation as a proximate mechanism underlying cleansing effects. This account differs from prevailing accounts in terms (...) of explanatory kind, interpretive parsimony, and predictive scope. Its unique and falsifiable predictions have received empirical support: Cleansing attenuates or eliminates otherwise observed influences of prior events across domains and across valences. Cleansing manipulations produce stronger effects the more strongly they engage sensorimotor capacities. Reversing the causal arrow, motivation for cleansing is triggered more readily by negative than positive entities. Conceptually similar effects extend to other physical actions of separation. On the flipside, grounded procedures of connection are also observed. Together, separation and connection organize prior findings relevant to multiple perspectives and open up new questions. Their predictions are more generalizable than the specific mappings in conceptual metaphors, but more fine-grained than the broad assumptions of grounded cognition. This intermediate level of analysis sheds light on the interplay between mental and physical processes. (shrink)

Although other quasi-Kantian theories have been adapted, Jürgen Habermas’s discourse theory has been largely ignored in discussions of environmental ethics. Indeed on some versions of what an environmental philosophy must entail, Habermas’s anthropocentric approach must be disqualified from the start. Yet, there are some environmentally friendly implications of his discourse theory. They may not give us everything we would wish, but in the contemporary political context we must treasure any moral theory that can draw on the still-extensive theoretical and political (...) resources of liberalism.

In two shocking articles that appeared in 1968 and 1974, Garrett Hardin argued that the population explosion was producing a “tragedy of the commons.” Since we lack an effective method of sharing common resources, the strong incentive for individuals to appropriate them selfishly would soon lead to their collapse. To mitigate this danger, Hardin proposed a “lifeboat ethic”: less populated and -polluted Western countries should deny food aid to developing nations, where it would save lives only to increase population pressure, (...) and they should close their borders to immigration to prevent their lifeboats from becoming overcrowded and going down with the rest. This paper challenges and complicates Hardin’s account of the tragedy. While there is something right about his view, its vulnerability to a series of empirical challenges reflects its conceptual limitations. I argue that we need to develop a broadly ethical and arguably religious solution to the twin challenges of population growth and pollution. If the liberal commitment to negative freedom is, ironically, largely responsible for our current ecological bind, our only hope of escape is to build bridges between traditions in search of a thicker sense of ethicopolitical obligation.

Since the appearance of Dodds's edition of Gorgias a number of the dialogues in tetr. I-VII have benefited from a re-examination of the evidence for the Platonic text—most notably Meno, tetr. IV, Parmenides, and Phaedrus. Recently the textual tradition of Phaedo has been studied by A. Carlini in a useful book which traces the fortunes of the text from antiquity until the time of the major manuscripts. The evidence thus accumulated goes some way to lessening a problem which has long (...) been obvious—the difficulty of studying the tradition of any single dialogue in isolation from the rest of the Platonic corpus. I propose to argue, however, that the bulk of evidence now available for several dialogues should not blind us to another hazard—that of attempting to fit dialogues showing different textual features into what is basically a single stemmatic pattern.

Libertarians such as J.R. Lucas have abandoned traditional Christian doctrines because they cannot reconcile them with the freedom of the will. Traditional Christian thinkers such as Augustine have repudiated libertarianism because they cannot reconcile it with the dogmas of the Faith. In Free Will and the Christian Faith, W.S. Anglin demonstrates that free will and traditional Christianity are ineed compatible. He examines, and solves, puzzles about the relationships between free will and omnipotence, omniscience, and God's goodness, using the idea of (...) free will to answer the question of why God allows evil, and presenting arguments that link free will to eternal life and to the nature of revelation. Topics covered include the meaning of life, the soul and Lesbegue measure, and strategies for discerning the voice of God. (shrink)

If K is an index of relative voting power for simple voting games, the bicameral postulate requires that the distribution of K -power within a voting assembly, as measured by the ratios of the powers of the voters, be independent of whether the assembly is viewed as a separate legislature or as one chamber of a bicameral system, provided that there are no voters common to both chambers. We argue that a reasonable index – if it is to be used (...) as a tool for analysing abstract, ‘uninhabited’ decision rules – should satisfy this postulate. We show that, among known indices, only the Banzhaf measure does so. Moreover, the Shapley–Shubik, Deegan–Packel and Johnston indices sometimes witness a reversal under these circumstances, with voter x ‘less powerful’ than y when measured in the simple voting game G1 , but ‘more powerful’ than y when G1 is ‘bicamerally joined’ with a second chamber G2 . Thus these three indices violate a weaker, and correspondingly more compelling, form of the bicameral postulate. It is also shown that these indices are not always co-monotonic with the Banzhaf index and that as a result they infringe another intuitively plausible condition – the price monotonicity condition. We discuss implications of these findings, in light of recent work showing that only the Shapley–Shubik index, among known measures, satisfies another compelling principle known as the bloc postulate. We also propose a distinction between two separate aspects of voting power: power as share in a fixed purse (P-power) and power as influence (I-power). (shrink)

Over the last few years, the concept of “wilderness” has come under attack by environmentalists deeply committed to sustaining the natural world. Their criticisms are pointed and undeniably strong; moreover as I will argue, very similar critiques could be made of its putative counter-concept, “the city.” Yet in both cases, we need not simply reject the concepts themselves as incoherent; our challenge is rather to develop resources rich enough to show that and why they must stand in a constructive tension. (...) I will close by outlining the possibility and productivity of this development through hermeneutic reflections inspired by the work of Hans-Georg Gadamer. (shrink)

'Thick neural event' is introduced to mean an event that requires firings of more than one neuron and a substantive (i.e. additional to merely temporal and spatial) relation among them. It is shown that some well regarded theories (e.g. by Lamme, Koch, etc.) strongly suggest that neural correlates of consciousness (NCCs) are thick neural events. It is then shown that thin (= not thick) neural events provide sufficient causation for neural events leading to behaviour, and that there are good reasons (...) to reject overdetermination by thick events. Thus, any physicalism that recognizes legitimacy of a search for NCCs must either reject theories that embrace thickness of NCCs, or accept the epiphenomenalistic view that the properties in virtue of which we are conscious are not properties in virtue of which events causally contribute to our behaviour.

by W. S. F. Pickering Durkheim's sociological approach to morals and moral systems has always aroused considerable interest, be it by way of criticism or ...

By arguing that his use of representations at the core of Durkheim's sociological thought, this book makes a unique contribution to Durkheimian studies which have recently been dominated by postivist and functionalist interpretaions, and reveals a thinker very much in tune with contemporary developments in philosophy, linguistics and sociology.

We characterize some large cardinal properties, such as μ-measurability and P 2 (κ)-measurability, in terms of ultrafilters, and then explore the Rudin-Keisler (RK) relations between these ultrafilters and supercompact measures on P κ (2 κ ). This leads to the characterization of 2 κ -supercompactness in terms of a measure on measure sequences, and also to the study of a certain natural subset, Full κ , of P κ (2 κ ), whose elements code measures on cardinals less than κ. (...) The hypothesis that Full κ is stationary (a weaker assumption than 2 κ -supercompactness) is equivalent to a higher order Lowenheim-Skolem property, and settles a question about directed versus chain-type unions on P κ λ.

We characterize some large cardinal properties, such as $\mu$-measurability and $P^2(\kappa)$-measurability, in terms of ultrafilters, and then explore the Rudin-Keisler (RK) relations between these ultrafilters and supercompact measures on $P_\kappa(2^\kappa)$. This leads to the characterization of $2^\kappa$-supercompactness in terms of a measure on measure sequences, and also to the study of a certain natural subset, $\mathrm{Full}_\kappa$, of $P_\kappa(2^\kappa)$, whose elements code measures on cardinals less than $\kappa$. The hypothesis that $\mathrm{Full}_\kappa$ is stationary (a weaker assumption than $2^\kappa$-supercompactness) is equivalent to (...) a higher order Lowenheim-Skolem property, and settles a question about directed versus chain-type unions on $P_\kappa\lambda$.

A fundamental philosophical question that arises in connection with evolutionary theory is whether the fittest patterns of behavior are always the most rational. Are fitness and rationality fully compatible? When behavioral rationality is characterized formally as in classical decision theory, the question becomes mathematically meaningful and can be explored systematically by investigating whether the optimally fit behavior predicted by evolutionary process models is decision-theoretically coherent. Upon investigation, it appears that in nontrivial evolutionary models the expected behavior is not always in (...) accord with the norms of the standard theory of decision as ordinarily applied. Many classically irrational acts, e.g. betting on the occurrence of one event in the knowledge that the probabilities favor another, can under certain circumstances constitute adaptive behavior.One interesting interpretation of this clash is that the criterion of rationality offered by classical decision theory is simply incorrect (or at least incomplete) as it stands, and that evolutionary theory should be called upon to provide a more generally applicable theory of rationality. Such a program, should it prove feasible, would amount to the logical reduction of the theory of rational choice to evolutionary theory. (shrink)
