Although coming from two very different paths, both Kant and Patañjali present similar strategies to refute the skeptic argument that denies the real and independent existence of physical objects. This essay examines both strategies through the reconstruction of Kant’s and Patañjali’s twofold refutation of idealism: one based on the perceptual distinction between the real and the illusory, and the other one based on the ontological necessity of a permanent external object to understand change. I argue that the second strategy is (...) philosophically stronger due to its phenomenological recognition of the body as a grounding point, and that this is possible only on account of an anti-realist conception of time. Both Kant and Patañjali utilize a similar line of realist argumentation while diverging in the type of realism that they each hold. (shrink)

The perceptual logic of j hintikka and r thomason is imbedded in a more general framework of quantification over individual-concepts. two intensional predicates for physical individuation and perceptual individuation are required in place of thomason's two variable-sorts. objectual perception of x by s is then definable as "for some y there is a perceptually individuated object z, in fact identical with x, such that s perceives that y is z.".

This article analyzes the thesis of ethical relativism, as defended by Alchourrón and Bulygin. These authors offer, on the one hand, a suggestive conception according to which the question “what are our obligations?” is equivalent to thinking about what is to be done; on the other hand, they defend a relativist conception of ethics. They present three objections to constructivist accounts of ethics that are not relativist: a) the argument of the burden of the proof; b) a version of the (...) dilemma of Euthyphro, and c) the argument of particularism. This article presents counterarguments to these objections in the attempt to show that they are not conclusive and that a space therefore remains for objectivity in the normative sphere. Keywords: Alchourrón-Bulygin, ethical relativism, ethical constructivism, burden of proof, particularism. (shrink)
