چکیده
I develop a syntactic concept of circularity, which I call propositional circularity. With respect to a given use of an argument advanced as a statement of inference for the benefit of a reasoner R, if the direct and indirect premises R would have to accept in order to accept the conclusion includes the conclusion, then the collection of premises is propositionally circular. The argument fails to display a type of inference that R can perform. Appealing to propositional circularity, I articulate a sufficient condition for a use of an argument to beg the question, highlighting why question-begging is a defect. Résumé: Je développe un concept syntaxique de la circularité, que je nomme la circularité propositionnelle. En ce qui concerne une utilisation donnée d'un argument avancé comme un énoncé d’une inférence pour le bénéfice d'un raisonneur R, si les prémisses directes et indirectes que R doit accepter pour accepter la conclusion comprennent la conclusion, alors l’ensemble des prémisses est propositionnellement circulaire. L'argument ne parvient pas à exprimer un type d'inférence que R peut effectuer. Je fais appel à la circularité propositionnelle pour décrire une condition suffisante pour un emploi d’un argument circulaire, en soulignant pourquoi un tel argument est défectueux.

Category-based induction from similarity of neural activation.
The idea that similarity might be an engine of inductive inference dates back at least as far as David Hume. However, Hume's thesis is difficult to test without begging the question, since judgments of similarity may be infected by inferential processes. We present a one-parameter model of category-based induction that generates predictions about arbitrary statements of conditional probability ...
متن کاملCan hungry nestlings be trained to reduce their begging?
Nestling begging behavior is usually characterized by a behavioral response of increasing begging levels with an increase in nestling need or hunger. Recent evidence for the possible effect of learning on begging intensity raises the question of how learning can shape this response rule. In particular, it is not clear whether hungry nestlings can learn to reduce their begging when it is not suc...
متن کاملA Mechanically Assisted Examination of Begging the Question in Anselm’s Ontological Argument
I use mechanized verification to examine several firstand higher-order formalizations of Anselm’s Ontological Argument against the charge of begging the question. I propose three different criteria for a premise to beg the question in fully formal proofs and find that one or another applies to all the formalizations examined. My purpose is to demonstrate that mechanized verification provides an...
متن کاملCooperative Begging in Banded Mongoose Pups
Vivid begging displays are common in species with parental care [1, 2]. They are usually seen as the way that rival offspring selfishly compete over parental investment [3], and individuals are expected to respond to the begging of rivals by increasing their own begging intensity [4, 5]. Here I show the opposite - that potential rivals gain direct benefits from begging by littermates, so that b...
متن کاملLogicism, interpretability, and Knowledge of Arithmetic
A crucial part of the contemporary interest in logicism in the philosophy of mathematics resides in its idea that arithmetical knowledge may be based on logical knowledge. Here an implementation of this idea is considered that holds that knowledge of arithmetical principles may be based on two things: (i) knowledge of logical principles and (ii) knowledge that the arithmetical principles are re...
