This essay discusses Cecilia Heyes’ groundbreaking new book Cognitive Gadgets: The Cultural Evolution of Thinking. Heyes’ point of departure is the claim that current theories of cultural evolution fail adequately to make a place for the mind. Heyes articulates a cognitive psychology of cultural evolution by explaining how eponymous “cognitive gadgets,” such as imitation, mindreading and language, mental technologies, are “tuned” and “assembled” through social interaction and cultural learning. After recapitulating her explanations for the cultural and psychological origins of these (...) gadgets, we turn to criticisms. Among those, we find Heyes’ use of evolutionary theory confusing on several points of importance; alternative theories of cultural evolution, especially those of the Tomasello group and of Boyd, Richerson and Henrich, are misrepresented; the book neglects joint attention and other forms of intersubjectivity in its explanation of the origins of cognitive gadgets; and, whereas Heyes accuses other theories of being “mindblind,” we find her theory ironically other-blind and autistic in character.

In his recent book “Becoming Human” Michael Tomasello delivers an updated version of his shared intentionality (SI) account of uniquely human cognition. More so than in earlier writings, the author embraces the idea that SI shapes not just our social cognition but all domains of thought and emotion. In this critical essay, we center on three parts of his theory. The first is that children allegedly have to earn the status of “second persons” through the acquisition of collective intentionality at (...) age 3. We make the case that humans take a second-personal stance toward others even as infants. The second point concerns Tomasello’s claim that 3-year-olds are group-minded and think in terms of “us” vs. “them”. We doubt both that children this young have a clear overview of their in- and out-groups and that they possess the “agonistic spirit” necessary for inter-group competition. Third, due to his focus on collective intentionality and how it might explain 3-year-olds’ difficulties with theory of mind problems, Tomasello appears to pay less attention to the crucial conceptual change that allows 4- to 5-year-olds to master such tasks.
