Refining the Skill Hypothesis: Replies to Andrews/Westra, Tomasello, Sterelny, and Railton

Abstract I reflect on the commentaries on my ‘skill hypothesis’ from Andrews/Westra, Tomasello, Sterelny, and Railton. I discuss the difference between normative cognition and the broader category of action-guiding representation, and I reflect on the relationship between joint intentionality and normative cognition. I then consider Sterelny and Railton’s variants on the skill hypothesis, which highlight some important areas where future evidence could help us refine the account: the relative importance of on-the-fly skill execution vs. longer-term strategizing, the relative importance of toolmaking vs. collaborative foraging, and the question of whether norms are encoded in control models themselves or in the goals and ideals that our control models help us pursue.
