Optionality in animal communication: a novel framework for examining the evolution of arbitrariness.

A critical feature of language is that the form of words need not bear any perceptual similarity to their function - these relationships can be 'arbitrary'. The capacity to process these arbitrary form-function associations facilitates the enormous expressive power of language. However, the evolutionary roots of our capacity for arbitrariness, i.

Teleology first: Goals before knowledge and belief.

Comparing knowledge with belief can go wrong in two dimensions: If the authors employ a wider notion of knowledge, then they do not compare like with like because they assume a narrow notion of belief. If they employ only a narrow notion of knowledge, then their claim is not supported by the evidence. Finally, we sketch a superior teleological view.

Minds, Brains, and Capacities: Situated Cognition and Neo-Aristotelianism.

This article compares situated cognition to contemporary Neo-Aristotelian approaches to the mind. The article distinguishes two components in this paradigm: an Aristotelian essentialism which is alien to situated cognition and a Wittgensteinian "capacity approach" to the mind which is not just congenial to it but provides important conceptual and argumentative resources in defending social cognition against orthodox cognitive (neuro-)science. It focuses on a central tenet of that orthodoxy.

Exorcising Grice's ghost: an empirical approach to studying intentional communication in animals.

Language's intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and mutual mindreading by a communicator and recipient. Whilst similar abilities in animals can shed light on the evolution of intentionality, they remain challenging to detect unambiguously.
