If one formulates Helmholtz's ideas about perception in terms of modern-day theories one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts. Using constructs from statistical physics it can be shown that the problems of inferring what cause our sensory inputs and learning causal regularities in the sensorium can be resolved using exactly the same principles. Furthermore, inference and learning can proceed in a biologically plausible fashion. The ensuing scheme rests on (...) Empirical Bayes and hierarchical models of how sensory information is generated. The use of hierarchical models enables the brain to construct prior expectations in a dynamic and context-sensitive fashion. This scheme provides a principled way to understand many aspects of the brain's organisation and responses. In this paper, we suggest that these perceptual processes are just one emergent property of systems that conform to a free-energy principle. The free-energy considered here represents a bound on the surprise inherent in any exchange with the environment, under expectations encoded by its state or configuration. A system can minimise free-energy by changing its configuration to change the way it samples the environment, or to change its expectations. These changes correspond to action and perception, respectively, and lead to an adaptive exchange with the environment that is characteristic of biological systems. This treatment implies that the system's state and structure encode an implicit and probabilistic model of the environment. We will look at models entailed by the brain and how minimisation of free-energy can explain its dynamics and structure. (shrink)

Karl Pfeifer attempts to present a coherent view of panentheism that eschews Pickwickian senses of “in” and aligns itself with, and builds upon, familiar diagrammed portrayals of panentheism. The account is accordingly spatial-locative and moreover accepts the proposal of R.T. Mullins that absolute space and time be regarded as attributes of God. In addition, however, it argues that a substantive parthood relation between the world and God is required. Pfeifer’s preferred version of panpsychism, viz. panintentionalism, is thrown into the (...) mix as an optional add-on. On this account, God is conceived of as a “spiritual field” whose nature can be made more intelligible by regarding “God” as having a mass-noun sense in some contexts. Pfeifer closes with the suggestion that we look to topology and mereology for further development of the position outlined in his paper. (shrink)

This article argues that, under likely empirical conditions, sufficientarianism leads not to an easily achievable duty to maintain a social minimum but to the onerous duty of maintaining a social maximum at the sufficiency level. This happens because sufficientarians ask us to give no weight at all to small benefits for people above the sufficiency level if the alternative is to relieve the suffering of people below it. If we apply this judgment in a world where there are rare diseases (...) and hard-to-prevent accidents that cause people to fall below the sufficiency threshold, all of our discretionary spending will have to be devoted to bringing harder and harder cases up to sufficiency. Nothing will be left for anyone to consume above the sufficiency level. (shrink)

This article argues the following points. The Hobbesian hypothesis, which we define as the claim that all people are better off under state authority than they would be outside of it, is an empirical claim about all stateless societies. It is an essential premise in most contractarian justifications of government sovereignty. Many small-scale societies are stateless. Anthropological evidence from them provides sufficient reason to doubt the truth of the hypothesis, if not to reject it entirely. Therefore, contractarian theory has not (...) done what it claims to do: it has not justified state sovereignty to each person subject to it by demonstrating that they benefit from that authority. To be justified in contractarian terms, states have to do something to improve the living standards of disadvantaged people under their rule. (shrink)

This book is an anthology of some of the most influential research on basic income in the period of roughly 1960-2010.

Although John Locke’s theory of appropriation is undoubtedly influential, no one seems to agree about exactly what he was trying to say. It is unlikely that someone will write the interpretation that effectively ends the controversy. Instead of trying to find the one definitive interpretation of Locke’s property theory, this article attempts to identify the range of reasonable interpretations and extensions of Lockean property theory that exist in the contemporary literature with an emphasis on his argument for unilateral appropriation. It (...) goes through Locke’s argument point-by-point discussing the controversy over what he said and over what he perhaps should have said to make the most valuable and coherent argument. The result is an outline of Lockean theories of property: a menu of options by which one might use appropriation to justify property rights. Supporters only need to pick the version they find most plausible, but opponents should be aware of the entire menu. Anyone claiming to refute appropriation-based property rights must address not only one but all potentially valid versions of it. (shrink)

Karl Pfeifer revisits Wittgenstein’s parenthetical allusion in the _Tractatus Logico-Philosophicus_ to the Grimms’ fairytale “The Golden Lads”, confirming that it does not work well as an illustration of the notion of “internal identity” that figures in Wittgenstein’s picture theory. He then proposes alternative ways of understanding the relationship of identity apparent in “The Golden Lads”.

This paper analyzes hegel's critique of kant's theoretical philosophy in terms of three specific objections to kant's transcendental deduction (concerning the representation of the i, The necessity of the categories, And the problem of a preliminary epistemology) and three specific objections to kant's transcendental idealism (concerning the thing in itself, The antinomies, And other specific problems of the transcendental dialectic).

This paper argues that a guaranteed income is not only consistent with the principle of reciprocity but is required for reciprocity. This conclusion follows from a three-part argument. First, if a guaranteed income is in place, all individuals have the same opportunity to live without working. Therefore, those who choose not to work do not take advantage of a privilege that is unavailable to everyone else. Second, in the absence of an unconditional income, society is, in effect, applying the principle, (...) “(S)he who does not work, will not eat.” If the application of this principle is to be consistent with reciprocity, it must be applied to everyone. Most modern industrial societies exempt many citizens from that choice. For example, the owners of external assets do not face the work-or-starve choice and do take advantage of a privilege that is not available to others. An unconditional guaranteed income is one way to eliminate that violation of reciprocity. Third, this paper addresses the criticism that the guaranteed income exploits middle-class workers by demonstrating that a basic income will have a positive effect on wages, which will at least partially counteract the effect of the taxes needed to pay for it.

Enrique Dussel's writings span the theology of liberation, critiques of discourse ethics, evaluations of Marx, Levinas, Habermas, and others, but most importantly, the development of a philosophy written from the underside of Eurocentric modernist teleologies, an ethics of the impoverished, and the articulation of a unique Latin American theoretical perspective. This anthology of original articles by U.S. philosophers elucidating Dussel's thought, offers critical analyses from a variety of perspectives, including feminist ones. Also included is an essay by Dussel that responds (...) to these essays. (shrink)

The introduction (pp. 7-29) discusses Nazi denigration of "Jewish philosophy, " from Spinoza to Bergson and Husserl, and the elevation of "German" philosophers, particularly Eckhart and Nietzsche, to the role of forerunners of Nazism. The chapters on the work of the four Jewish philosophers mention briefly their murder by the Nazis (in the case of Benjamin, his death while fleeing the Nazis).

We explore the nature of forgetting in a corpus of 125,000 students learning Spanish using the Rosetta Stone® foreign-language instruction software across 48 lessons. Students are tested on a lesson after its initial study and are then retested after a variable time lag. We observe forgetting consistent with power function decay at a rate that varies across lessons but not across students. We find that lessons which are better learned initially are forgotten more slowly, a correlation which likely reflects a (...) latent cause such as the quality or difficulty of the lesson. We obtain improved predictive accuracy of the forgetting model by augmenting it with features that encode characteristics of a student's initial study of the lesson and the activities the student engaged in between the initial and delayed tests. The augmented model can predict 23.9% of the variance in an individual's score on the delayed test. We analyze which features best explain individual performance. (shrink)

Karl Pfeifer argues against the view that an aesthetic experience must be a uniquely special kind of experience by means of an analogy with sexual experiences. Nonetheless, he leaves open the possibility that some aesthetic experiences might still be of a special kind.

Karl Pfeifer distinguishes between humor used extraneously in the delivery of philosophical content and humor intrinsic to the content itself: “Enlivening the delivery isn’t the same as enlivening the content of the delivery.” Using examples from topics in philosophy of mind and moral philosophy he illustrates how humor can be used to make certain ideas more engaging and memorable for students. He also gives an example of what to avoid.

Durante los años 1853 y 1854 surgió una ola de huelgas en varios distritos industriales de Inglaterra, especialmente en los sectores textiles de Lancashire y Manchester. Este ciclo de luchas, que pugnaba principalmente por un aumento de los salarios, fue visto por Ernest Jones y el movimiento Cartista como una oportunidad para organizar una asociación obrera a escala nacional. Karl Marx, que compartía la visión de los cartistas, analizó el movimiento desde el New York Tribune, brindando apoyo a la (...) iniciativa a la que dio lugar: el Parlamento Obrero. A continuación, se ofrece la traducción de cuatro textos periodísticos que Marx publicó en apoyo a la institución obrera –la mayoría inéditos en español–, seguidos de «Las luchas por la organización obrera en la época victoriana (1853-1854)», un estudio crítico sobre el ciclo de huelgas y las expectativas de organización obrera durante aquellos años, donde se defiende que este fallido intento de organización constituye un precedente de la sección británica de la Asociación Internacional de Trabajadores. La traducción y edición de los textos de Marx, y el estudio crítico que los acompaña, han sido realizados por Mario Espinoza Pino (Universidad de Granada). (shrink)

Senza una filosofia della storia, la storia non è altro che un incomprensibile susseguirsi di eventi che non trasmette le autentiche motivazioni umane ad agire. Capire il fine ultimo della storia significa porsi in un'ottica assoluta, metafisica, abbandonando la concezione del corpo sociale come semplice lotta per la sopravvivenza. In questo senso la filosofia è sorella della teologia come dimostrano, secondo Karl Lowith, le tappe fondamentali del pensiero europeo. Dalla Bibbia a sant'Agostino, da Voltaire a Marx, da Vico a (...) Hegel, l'interpretazione filosofica della storia rimane ancorata a un'originaria matrice religiosa. Anche quando alla fede e all'idea di provvidenza sostituisce quella di progresso. (shrink)
