Is backing grounding?

Separatists are grounding theorists who hold that grounding relations and metaphysical explanations are distinct, yet intimately connected in the sense that grounding relations back metaphysical explanations, just as causal relations back causal explanations. But Separatists have not elaborated on the nature of the ‘backing’ relation. In this paper, I argue that backing is a form of (partial) grounding. In particular, backing has many of the properties commonly attributed to grounding, and taking backing to be partial grounding allows Separatists to make the most of their position vis-à-vis their Unionist opponents.     

How does information from low and high spatial frequencies interact during scene categorization?

Current models of visual perception suggest that, during scene categorization, low spatial frequencies (LSF) are rapidly processed and activate plausible interpretations of visual input. This coarse analysis would be used to guide subsequent processing of high spatial frequencies (HSF). The present study aimed to further examine how information from LSF and HSF interact and influence each other during scene categorization. In a first experimental session, participants had to categorize LSF and HSF filtered scenes belonging to two different semantic categories (artificial vs. natural). In a second experimental session, we used hybrid scenes as stimuli made by combining LSF and HSF from two different scenes which were semantically similar or dissimilar. Half of the participants categorized LSF scenes in hybrids, and the other half categorized HSF scenes in hybrids. Stimuli were presented for 30 or 100?ms. Session 1 results showed better performance for LSF than HSF scene categorization. Session 2 scene categorization was faster when participants attended and categorized LSF than HSF scene in hybrids. The semantic interference of a semantically dissimilar HSF scene on LSF scene categorization was greater than the semantic interference of a semantically dissimilar LSF scene on HSF scene categorization, irrespective of exposure duration. These results suggest a LSF advantage for scene categorization, and highlight the prominent role of HSF information when there is uncertainty about the visual stimulus, in order to disentangle between alternative interpretations.     

Global government or global governance? Realism and idealism in Kant's legal theory

Did Kant believe we need a world government? It has been a matter of controversy in Kant scholarship whether Kant endorsed the creation of a world state or merely a voluntary federation of states with no coercive power. I argue that Kant's main concern was with a global juridical condition, which he regarded as a rational requirement given the equal freedom and equality of individuals. However, he recognized that implementing this rational ideal requires sensitivity to contingent aspects of world politics. I will argue that Kant offers an ideal theory not disentangled from realist considerations and that he adopts what I will call methodological realism: the attempt to realize the requirements of Right (Recht) in a world governed by its own laws and mechanisms. I will illustrate this interpretation with Kant's discussion of the right of nations (Völkerrecht). The confusion in regard to Kant's actual position on the matter, I will argue, is a direct consequence of Kant's methodological realism. The article concludes by showing how Kant’'s ideas and methods can inspire us to rethink global institutions for our current global challenges.
