This paper seeks to explore the way Giovanni Pico della Mirandola treated the Orphics and the Pythagoreans in his Conclusiones nongentae, his early and most ambitious work, so that he formulates his own philosophy. I do not intend to present and analyze the sum of Pico’s references to Orphics and Pythagoreans, since such an attempt is beyond the scope of this paper. Rather, I aim to highlight certain Pico’s aphorisms that allow readers to understand and evaluate his syncretic method and (...) his goals. In addition, I attempt to trace Pico’s sources and evaluate his proper knowledge, understanding and treatment of the Orphics and the Pythagoreans. Pico resorts to the Orphics and the Pythagoreans because he wants to give a practical and applied dimension to his philosophy. He attempted the revival of the original wisdom that underlies the traditions he combined. He was not a fan of the Aristotelian θεωρίης ἢνεκεν. Philosophy does not aim at proper knowledge, but is the key for the manipulation of the cosmos, physically and metaphysically speaking. Pico probably thinks of himself as the modern Orpheus: he does not intend to reveal the paths which cross the sensible and the intelligible, but he aspires to tread them. (shrink)

This special issue collects together nine new essays on logical consequence :the relation obtaining between the premises and the conclusion of a logically valid argument. The present paper is a partial, and opinionated,introduction to the contemporary debate on the topic. We focus on two influential accounts of consequence, the model-theoretic and the proof-theoretic, and on the seeming platitude that valid arguments necessarilypreserve truth. We briefly discuss the main objections these accounts face, as well as Hartry Field’s contention that such objections (...) show consequenceto be a primitive, indefinable notion, and that we must reject the claim that valid arguments necessarily preserve truth. We suggest that the accountsin question have the resources to meet the objections standardly thought to herald their demise and make two main claims: (i) that consequence, as opposed to logical consequence, is the epistemologically significant relation philosophers should be mainly interested in; and (ii) that consequence is a paradoxical notion if truth is.

I argue that the standard anti-realist argument from manifestability to intuitionistic logic is either unsound or invalid. Strong interpretations of the manifestability of understanding are falsified by the existence of blindspots for knowledge. Weaker interpretations are either too weak, or gerrymandered and ad hoc. Either way, they present no threat to classical logic.

The first half of Mark Quentin Gardiner’s recent book, Semantic Challenges to Realism: Dummett and Putnam, is a sustained, systematic, and, for the most part, novel attempt to demolish the case against semantic realism instigated by Michael Dummett. In this article I reply on the anti-realist’s be-half. I aim to demonstrate that none of Gardiner’s main anti-Dummettian arguments are successful, and moreover that his errors are, in the main, consequences of serious misconstruals of vital aspects of the semantic realist and (...) anti-realist positions.
