This course will explore some key ideas in the recent study of the origins and
evolution of language. On the one hand, we will pay some attention to formal
and computational models of language evolution—although always keeping the
focus on the philosophical import of such models. On the other hand, we will
review some prominent contemporary ideas about signaling in animals and early
humans.
This is a tentative list of readings, and of the lectures that will discuss them.
There will likely be changes in both, but this should give you a good idea of what to expect from the course.
• Week 1: Course overview.
Weeks 2, 3 and 4: communication and cooperation
• We first introduce the sender-receiver framework
– Ideas in game and information theory to model cooperation and some of its constraints.
– Skyrms, Signals, chaps. 2 and 3
• We will then discuss the problem of cooperation in the face of deception and free-riding
– Skyrms, The Stag Hunt, chapters 1, 2 and 3.
• Finally, we wil look into how animal communication, and animal cognition in general, presents features we associate with language proper.
– Fitch, The evolution of language, chapter 4
Weeks 5, 6, 7 and 8: Primate and Early Human Communication
• Cheney and Seyfarth, Baboon Metaphysics
• Planer and Sterelny, From signal to symbol
• Tomasello, Origins of Human Communication
• Hrdy and Burkart, The emergence of emotionally modern humans
• We are going to explore two different, to an extent antagonistic, ideas:
1. Tomasello, Planer & Sterelny, Htrdy and Burkart: Language depends on a mutualistic and altruistic substrate, that exists only in humans and (to a much lesser extent) great apes – this presumably is facilitated by the presence of common interest.
2. Cheney and Seyfarth: at least some of the cognitive capabilities that will eventually be deployed in language use depend on imperfect common interest – the Machiavellian need to navigate dangerous and complicated social structures.
Weeks 9 and 10: Computational Models
• We revisit formal models of the evolution of language, with our newly gained understanding.
– Kirby et al., Compression and communication in the cultural evolution of linguistic structure
– Steels, Grounding symbols through evolutionary language games
• Week 11: Conclusions
