The concern about man's harmful impact on the environment focuses attention on the external environment, i.e., the real world out there, which may not survive in a form to support life. But supporting life of an individual is in the hands of that individual's brain, which is primarily concerned with various needs of the internal environment, also referred to as the self. Confronted with diverse and often competing needs, the brain has evolved a complexity in man, which makes it doubtful (...) that any one collective strategy may be effective in preserving the external environment.

In a quest for honesty, Kaufmann argues against organized religion and presents his own views on the meaning of faith, morality, theology, suffering, and death.

Husserl's theory of perception is remarkable in several respects. For one thing, Husserl rigorously distinguishes the parts and properties of the act of consciousness - its content -from the parts and properties of the object perceived. Second, Husserl's repeated insistence that perceptual consciousness places its subject in touch with the perceived object itself, rather than some representation that does duty for it, vindicates the commonsensical and phenomenologically grounded belief that when a thing appears to us, it is precisely that thing, (...) rather than some other thing (its 'appearance'), that we perceive. Third, his distinction between empty and intuitive acts, and his descriptions of their complex interplay in perceptual consciousness, provides a way of making sense of the fact that an object can be perceived even when some of its parts and properties are not. Finally, his theory of perceptual acts as constituents of higher-order acts of fulfilment provides one of the few detailed accounts in the philosophical literature of how a perceptual experience can transform a mere thought into knowledge, despite the fact that the relation between perception and belief is not a logical or inferential one. Because Husserl's theory of perception is a serious candidate for truth, it is also a serious candidate for philosophical criticism. As such, in what follows I will treat it as a live force to be reckoned with rather than a historical curiosity. (shrink)

In this article, I respond to commentaries by Eva Jablonka and Simona Ginsburg and by David Spurrett on my target article “Complexity and the Evolution of Consciousness,” in which I have offered the first extended articulation of my pathological complexity thesis as a hypothesis about the evolutionary origins and function of consciousness. My reply is structured by the arguments raised rather than by author and will offer a more detailed explication of some aspects of the pathological complexity thesis.

The conception of a ‘law of nature’ is a human product. It was created to play a role in natural philosophy, in the Cartesian tradition. In light of this, philosophers and scientists must sort out what they mean by a law of nature before evaluating rival theories and approaches. If one’s conception of the laws of nature is yoked to metaphysical notions of truth and explanation, that connection must be made explicit and defended. If, on the other hand, one’s aim (...) is to disentangle laws from truth or from explanation, that must be stated and defended as well. If philosophers do not make such assumptions, intuitions, and methodological commitments clear, then it will be impossible to identify the source of disagreement in debates about the laws of nature. Are the conflicts rooted in disagreement about the conclusions reached, or do the background commitments of the combatants block any resolution to the dispute in principle or in practice? (shrink)

This paper defends that the both the Buddhist tradition and the Aristotelian allow us to think of the distinction between to reason with contradictions and to accept them, understanding ' accept a contradiction ' by taking it as consistent. From this viewpoint, none of two would disagree with most contemporary paraconsistent views. The conclusions are, thus, that, firstly, there is no compelling reason to endorse any kind of metaphysical dialetheism, and, second, that a coherent form of reasoning with contradictory statements (...) is neither opposed to the Aristotelian conception of logic, nor to certain texts in the Buddhist tradition, as the Madhyamikas.

We present a meta-analytic review on the processing of negations in conditional reasoning about affirmation problems (Modus Ponens: “MP”, Affirmation of the Consequent “AC”) and denial problems (Denial of the Antecedent “DA”, and Modus Tollens “MT”). Findings correct previous generalisations about the phenomena. First, the effects of negation in the part of the conditional about which an inference is made, are not constrained to denial problems. These inferential-negation effects are also observed on AC. Second, there generally are reliable effects of (...) a negation in the clause referred to by the categorical premise, and these referred-negation effects are constrained to the logically fallacious AC and DA inferences. All findings are presented and discussed in relation to contemporary mental model (MM) and mental logic (ML) theories. It is argued that a double-negation elimination hypothesis provides a sufficient explanation of inferential-negation effects within both MM theory and ML theory, if the latter is extended by a validating search for counter examples. Both MM and ML theories adhere to a processing scheme that allows them to incorporate an account of referred-negation effects based on the thesis that counter-example frequency is modulated by the scope of a contrast class delineated by a false affirmative. We conclude that MM and ML theories provide adequate processing schemes to accommodate for the explanatory hypotheses, at least in principle. In practice, both approaches remain equivocal as regards the connectivity and interactivity with long-term memory knowledge invoked in generating, manipulating, and testing the mental representations of negative state of affairs.

This paper provides an axiomatic analysis of sufficientarian social evaluation. Sufficientarianism has emerged as an increasingly important notion of distributive justice. We propose a class of principles that we label generalized critical-level sufficientarian orderings. The distinguishing feature of our new class is that its members exhibit constant critical levels of well-being that are allowed to differ from the threshold of sufficiency. Our basic axiom assigns priority to those below the threshold, a property that is shared by numerous other sufficientarian approaches. (...) When combined with the well-known strong Pareto principle and the assumption that there be a constant critical level, the axiom implies that the critical level cannot be below the threshold. The main results of the paper are characterizations of our new class and an important subclass. As a final observation, we identify the generalized critical-level sufficientarian orderings that permit us to avoid the repugnant conclusion and the sadistic conclusion, which are known as two fundamental challenges in population ethics.

"The time-honored dualism of the mutually exclusive systems of thought, mechanistic biology on the one hand and vitalism on the other, expresses a pair of theoretical approaches which are both inadequate. We shall show how they can be replaced by an abstractly descriptive system of a different type that is far better adapted to the nature of biology"--Preface.

In 1999, a case was described on national television in which a woman had enlisted onto an international bone marrow registry with the altruistic desire to offer her bone marrow to some unidentified individual in need of a transplant. The potential donor then was notified that she was a compatible match with someone dying from leukemia and gladly donated her marrow, which cured the recipient of the disease. Years later, though, the recipient developed end-stage renal disease, a consequence of the (...) high-dose chemotherapy she received earlier to destroy her stem cells and prepare her for the bone marrow transplant. Finding a suitable donor for a kidney transplant proved extremely difficult. Desperate, she requested that the donor registry personnel help her locate the individual who earlier was determined to be a compatible donor and asked this now-identifiable individual to consider donating one of her two normally functioning kidneys for a kidney transplant.

This book develops a bold poetics based on the author's critical reexamination of the views of Plato.

Although a very recent topic in contemporary logic, the subject of combinations of logics has already shown its deep possibilities. Besides the pure philosophical interest offered by the possibility of defining mixed logic systems in which distinct operators obey logics of different nature, there are also several pragmatical and methodological reasons for considering combined logics. We survey methods for combining logics (integration of several logic systems into a homogeneous environment) as well as methods for decomposing logics, showing their interesting properties (...) and applications.

Despite their influence on later philosophers such as Hume, Malebranche's central arguments for occasionalism remain deeply puzzling. Both the famous ‘no necessary connection’ argument and what I call the epistemic argument include assumptions – e.g., that a true cause is logically necessarily connected to its effect – that seem unmotivated, even in their context. I argue that a proper understanding of late scholastic views lets us see why Malebranche would make this assumption. Both arguments turn on the claim that a (...) volition is the only candidate for a cause, because only a volition can include an effect as its intentional content. (shrink)

Teachers in many countries complain that their pedagogic work is impeded by unreasonable bureaucratic demands by government agencies. This paper suggests that historical, institutional and cultural perspectives are needed to understand the processes at work. It draws on Weber’s classic study of bureaucracy, but also makes reference to claims that traditional bureaucracies have been modified in ways that ameliorate their authoritarian character. The central part of the paper examines the attempts of one country (Scotland) to address complaints about excessive bureaucracy: (...) it is argued that they show a limited understanding of the nature of institutional power. In the discussion that follows, a number of critical interpretations are considered: that bureaucracies are, by their very nature, anti-educational; that they undermine ethical consciousness and cause psychological damage; and that enhanced professionalism can serve as a counterweight to bureaucratic tendencies. The paper ends by suggesting that the powerful pragmatic argument that mass, state-run educational systems cannot function without complex administrative structures, should not be used to disguise the fact that they have unintended consequences, some of which tend to subvert their stated aims.

In the world of Philosophy for Children, the word “method” is found frequently in its literature and in its practitioner’s handbooks. This paper focuses on the idea of community of philosophical inquiry as P4C’s methodological framework for educational purposes, and evaluates that framework and those purposes in light of the question, what does it mean to bring children and philosophy together, and what methodological framework, if any, is appropriate to that project? Our broader aim is to highlight a problem with (...) regards to the concept of method in P4C, and to question the consequences of that concept in the practice of philosophical dialogue with children. To better situate the concept of method within P4C, we will identify two different historical understandings—represented by Rene Descartes and Hans Georg Gadamer—of the concept, and suggest new possibilities for understanding philosophical practice with children in light of their difference.

Rent control is an economic abomination. It diverts investments away from residential rent units, it leads to their deterioration, it is responsible for urban decay such as in the South Bronx, it does not help poor tenants, it is a horrendous means of income redistribution. Yet this economic regulation is beloved of intellectuals (hot beds of pro rent control sentiment are Berkeley, Ann Arbor and Cambridge) particularly in the legal and philosophical communities. The present article is dedicated to an exploration (...) and rejection of the arguments in behalf of rent control which emanate from this source. (shrink)

Heumer and I debate animal rights, utilitarianism, libertarianism, morality and philosophy. We agree that suffering is a problem, and diverge, widely, on how to deal with it. I maintain that this author’s reputation as a libertarian, let alone an intellectual leader of this movement, is problematic. Why? That is because libertarianism, properly understood, is a theory of intra-human rights; this philosophy says nothing about right from an extra-human perspective, Heumer to the contrary notwithstanding. That is to say, he is improperly (...) importing into the freedom philosophy considerations extraneous to it. (shrink)

A number of studies have demonstrated pragmatic language difficulties in people with Schizophrenia Spectrum and Other Psychotic Disorders. However, research about how people with schizophrenia spectrum and other psychotic disorders understand scalar implicatures is surprisingly rare, since SIs have generated much of the most recent literature. Scalar implicatures are pragmatic inferences, based on linguistic expressions like some, must, or, which are part of a scale of informativeness. Logically, the less informative expressions imply the more informative ones, but pragmatically people usually (...) infer that the presence of a less informative term implies that the more informative term was not applicable. In one of the few existing studies with people with schizophrenia spectrum and other psychotic disorders, Wampers et al. observed that in general, people with schizophrenia spectrum and other psychotic disorders were less likely to derive SIs than controls. The current study has three main aims. First, we want to replicate the original finding with the scalar terms some-all. Second, we want to investigate how these patients deal with different scalar terms, that is, we want to investigate if scalar diversity is also observed in this clinical group. Third, we investigate the role of working memory, often seen as another important mechanism to enable inferring SIs. Twenty-one individuals with a psychotic disorder and 21 matched controls answered 54 under-informative statements, in which seven different pairs of scalar terms were used. In addition, working memory capacity was measured. Patients with schizophrenia spectrum and other psychotic disorders did not make more logical interpretations when processing quantifiers, disconfirming Wampers et al.. However, certain scalar scales elicited more pragmatic interpretations than others, which is in line with the scalar diversity hypothesis. Additionally, we observed only partial evidence for the role of working memory. Only for the scalar scale and-or, a significant effect of working memory was observed. The implications of these results for patients with schizophrenia spectrum and other psychotic disorders are discussed, but also the role of working memory for pragmatic inferences, as well as the place of SIs in experimental pragmatics.
