Hume's “Wilt Chamberlain Argument” and taxation

Robert Nozick addresses the idea of egalitarian redistribution in an argument standardly considered original: the “Wilt Chamberlain Argument”. However, this argument (without reference to Wilt Chamberlain) is found in David Hume's AnEnquiry Concerning the Principles of Morals, first published in 1751. Placing this argument within a Humean and Hayekian, rather than a Lockean or Kantian, perspective radically changes its import for issues of economic justice. Rather than vindicating the radical individualism of Nozick and other libertarians, applied to our circumstances using Hume's conventionalist and evolutionary account of justice, Hume's Wilt Chamberlain argument vindicates moderate redistribution constrained by the rule of general laws and the goal of fostering innovation and industriousness.     

The “BIG BIRD” of the “YELLOW YOUNG” man: Do nontarget properties cascade?

This study investigated whether in speech production object properties flow in a cascaded manner or whether cascaded processing is restricted to the object's identity. In Experiments 1 and 2, participants saw pictured objects and had to state either their size (GRAND or PETIT—meaning big and small) or their name. The size of the objects varied as a function of the way they were presented on the computer screen (Experiment 1) or their real size in the world (Experiment 2). In Experiment 3, faces of young and old men were coloured in yellow or in green. The task was to name either the colour (JAUNE or VERT, meaning yellow and green, respectively) or the age (JEUNE or VIEUX, meaning young and old, respectively) of the face. In Experiments 1 and 2, no reliable effects of phonological relatedness (“GORILLE–grand”—a big gorilla) were found on the object-naming latencies. However, size-naming latencies were shorter when the adjective shared the initial phoneme of the picture name (i.e., “GRAND–gorille”) than when it did not (i.e., “GRAND–dinosaure”—saying “big” in response to a big dinosaur). In Experiment 3, phonological overlap did not affect colour naming latencies, or age naming latencies. Overall, these findings strongly suggest that cascaded processing is restricted to the object's identity in conceptually driven naming tasks.     

Relational property between head and eye regions is the primary determinant of the efficiency in search for a deviant gaze

The human visual system is extremely sensitive to the directions of the gazes of others. However, the mechanism underlying gaze direction perception has yet to be clarified. The primary aim of the present study is to investigate whether the relational property between the local eye region and other facial regions serves as the primary visual system cue in detecting a direct gaze. Our results showed that search efficiency was determined primarily by the gaze direction indicated by the relational property regardless of the direction indicated by the local feature information of the eye region; this was true even when the gaze directions indicated by these two types of information were conflicting. These results bolster the hypothesis that the human visual system primarily accesses socially meaningful information in searching for a deviant gaze.     

Screw dislocation in functionally graded magnetoelectroelastic solids

A screw dislocation in a functionally graded magnetoelectroelastic material is investigated. The material properties exponentially changing along both x and y directions are considered and the mechanical–electric–magnetic coupling is discussed. Closed-form expressions for the mechanical, electric and magnetic components are derived using the general stress function method. The solutions can be applied as a fundamental result and reduced into the classic and piezoelectric cases. The study puts forth a direct way for screw dislocation analysis in inhomogeneous structures with multifield coupling.

Rule Separation and Embedding Theorems for Logics Without Weakening

A full separation theorem for the derivable rules of intuitionistic linear logic without bounds, 0 and exponentials is proved. Several structural consequences of this theorem for subreducts of (commutative) residuated lattices are obtained. The theorem is then extended to the logic LR ⁺ and its proof is extended to obtain the finite embeddability property for the class of square increasing residuated lattices.     

The Pursuit of Epistemic Good

Pace Zagzebski, there is no route from the value of knowledge to a non–reliabilist virtue–theoretic epistemology. Her discussion of the value problem is marred by an uncritical and confused employment of the notion of a "state" of knowledge, an uncritical acceptance of a "knowledge–belief" identity thesis, and an incoherent presumption that the widely held thought that knowledge is more valuable than true belief amounts to the view that knowledge is a state of true belief having an intrinsic property which a state of 'mere" true belief lacks. Her arguments against a "machine–product" conception of knowledge are undermined by these flaws, while the alternative "agent–act" model she recommends is unattractive, at odds with the knowledge–belief identity thesis she favours, and no solution to the problem of the value of knowledge she poses. I end with the observation that her version of virtue–theoretic epistemology points in the direction of cognitive decision–theoretic norms, and I briefly discuss the bearing of this fact upon her viewpoint.     

休谟的经济正义思想

休谟从分析人类获取生活资料的方式入手,认为正义是一种社会契约,是尊重个人财产权的人为美德;他提出了正义的三大法则,即财产稳定地占有的法则,根据同意转移所有物的法则,履行许诺的法则,并强调政府在落实经济正义三大法则过程中的作用。休谟的经济正义思想反映了市场经济的某些一般特征,对于今天我们研究中国社会的经济正义问题仍有不可替代的借鉴价值。     

Multimo dal Logics of Products of Topologies

We introduce the horizontal and vertical topologies on the product of topological spaces, and study their relationship with the standard product topology. We show that the modal logic of products of topological spaces with horizontal and vertical topologies is the fusion S4 ⊕ S4. We axiomatize the modal logic of products of spaces with horizontal, vertical, and standard product topologies.We prove that both of these logics are complete for the product of rational numbers ℚ × ℚ with the appropriate topologies.
