The object of this paper is to sketch an approach to propositions, meaning and names. The key ingredients are a Twin-Earth-inspired distinction between internal and external meaning, and a middle-Wittgenstein-inspired conception of internal meaning as role in language system. I show how the approach offers a promising solution to the problem of the meaning of proper names. This is a plea for a neglected way of thinking about these topics.

Vice essentialism is the view that epistemic vices have robustly negative effects on our epistemic projects. Essentialists believe that the manifestation of epistemic vices can explain many of our epistemic failures, but few, if any, of our epistemic successes. The purpose of this paper is to argue that vice essentialism is false. In §1, I review the case that some epistemic vices, such as closed-mindedness and extreme epistemic deference, have considerably beneficial effects when manifested in collectivist contexts. In §2, I (...) add that there are putative epistemic vices whose repeated manifestation leads to significant epistemic achievements over time. Epistemic recklessness is one such unstable vice. Though Sosa argues that epistemically reckless judgements cannot constitute knowing full well, the repeated manifestation of epistemic recklessness is essential to our becoming fully well knowledgeable in the long run. Without making incompetent judgements in environments that offer unambiguous, actionable feedback, we could not develop the intuitive and reflective competences and meta-competences required for knowing full well.

Alonzo Church (1903–1995) was a renowned mathematical logician, philosophical logician, philosopher, teacher and editor. He was one of the founders of the discipline of mathematical logic as it developed after Cantor, Frege and Russell. He was also one of the principal founders of the Association for Symbolic Logic and the Journal of Symbolic Logic. The list of his students, mathematical and philosophical, is striking as it contains the names of renowned logicians and philosophers. In this article, we focus primarily on (...) Church’s philosophical contributions. (For an account of his life and academic history see the Introduction to The Collected Works of Alonzo Church (2019).) However, we also discuss his mathematical results when it is desirable to do so in order to pursue a philosophical issue. (shrink)
