Chimpanzees and humans are close evolutionary relatives who behave in many of the same ways based on a similar type of agentive organization. To what degree do they experience the world in similar ways as well? Using contemporary research in evolutionarily biology and animal cognition, I explicitly compare the kinds of experience the two species of capable of having. I conclude that chimpanzees’ experience of the world, their experiential niche as I call it, is: intentional in basically the same way (...) as humans’; rational in the sense that it is self-critical and operates with logically structured causal and intentional inferences; but not normative at all in that it does not operate with “objective” evaluative standards. Scientific data do not answer philosophical questions, but they provide rich raw material for scientists and philosophers alike to reflect on and clarify fundamental psychological concepts. (shrink)

I argue that uniquely human forms of ‘Theory of Mind’ are a product of cultural evolution. Specifically, propositional attitude psychology is a linguistically constructed folk model of the human mind, invented by our ancestors for a range of tasks and refined over successive generations of users. The construction of these folk models gave humans new tools for thinking and reasoning about mental states—and so imbued us with abilities not shared by non-linguistic species. I also argue that uniquely human forms of (...) ToM are not required for language development, such that an account of the cultural origins of ToM does not jeopardise the explanation of language development. Finally, I sketch a historical model of the cultural evolution of mental state talk. (shrink)

This manuscript explores intersubjectivity through a conceptual construct for meaning-making that emphasizes three major interrelated elements–meaning making in interaction, making meaning with the body as well as the mind, and meaning making within an open dynamic system. These three elements are present in the literature on intersubjectivity with a wide range of terms used to describe various theoretical formulations. One objective of this manuscript is to illustrate how such a construct can be useful to understand the meaning-making observed in psychoanalysis, (...) such as in the treatment of a young child on the autistic spectrum. The challenges in establishing an intersubjective state with a child on the autistic spectrum serve to highlight important features of intersubjectivity. As an important background to this clinical illustration, we illustrate the construct with the scientific paradigm of the well-known face-to-face still-face. (shrink)

Disagreement remains about whether particular human socio-cognitive traits arose primarily as a result of biological adaptations, or because of changing cultural practices. Heyes argues that uniquely human traits, including imitation and theory of mind, are the product of cultural learning. In contrast, Tomasello argues that they are, in key respects, part of a suite of adaptations for ‘shared intentionality’. We consider how such disagreements might be resolved. We show that the kinds of consideration often used to adjudicate questions about trait (...) origins are insufficient to settle origin questions. Furthermore, humankind’s immersion in culture undermines the prospect that cross-cultural and developmental studies could resolve origin questions. Nonetheless we argue that, when cautiously interpreted, currently neglected studies of enculturated great apes (i.e. apes raised in human environments) can shed new light on trait origins, and inform mechanistic accounts of cognitive development. While acknowledging the shortcomings of enculturation research, we argue that it deserves renewed attention. (shrink)

Orthodoxy has it that language evolution requires Gricean communicative intentions and therefore an understanding of nested metarepresentations. The problem with this orthodoxy is that it is hard to see how non-linguistic creatures could have such a sophisticated understanding of mentality. Some philosophers like Bar-On (The Journal of Philosophy 110 (6): 293-330, 2013a; Mind and Language 28 (3): 342-375, 2013b) have attempted to develop a non-Gricean account of language acquisition building on the information-rich and subtle communicative powers of expressive behaviours. This (...) paper argues that this approach shares a number of instructive similarities with the literature on the cognitive conception of language. It shows how expressive accounts (and others) can learn from insights in that tradition and identifies a problem with the role of intentional actions in expressive accounts that can be solved by understanding expressive behaviours more as cognitive rather than communicative tools.

The common-sense view that reasons guide us in thought and action and that humans are essentially reason-responsive animals is increasingly under attack by defenders of what one can call the Rationalisation View, which emphasises that we typically rationalise actions and judgements that are based on intuition rather than reasoning. This article defends the former view of human Reason, partly by replying to prominent advocates of the latter, partly by proposing accounts of reflective reasoning and rationalisation that bring to light a (...) common, underappreciated feature: they both involve the capacity to see considerations as reasons. This capacity, the author conjectures, should be the starting point for investigating the faculty we call ‘Reason’, its evolutionary origin, and the (ir)rationality of different kinds of thought associated with it.

The tendency for people to remember less as members of a group than they would be capable of were they to remember alone is a phenomenon known as collaborative inhibition. The article offers a phenomenological account of this highly counterintuitive effect of group remembering. It argues that the mutual failure to live up to one’s potential does not warrant the standard, strongly negative views about the role of others in recall. Rather, the phenomenon may imply that sharedness itself becomes constitutive (...) of the process in the sense that interaction partners co-determine what and how to remember. Drawing on phenomenological approaches to remembering and second-person engagement, the article argues that individuals participating in shared remembering co-construct their memories by reciprocally and dynamically incorporating each other’s perspectives, attitudes, and emotions about their shared past.

In this paper, I approach epistemic norms from an ontogenetic point of view. I argue and present evidence that to understand epistemic norms – e.g., scientific norms of methodology and the evaluation of evidence – children must first develop through their social interactions with others three key concepts. First is the concept of belief, which provides the most basic distinction on which scientific investigations rest: the distinction between individual subjective perspectives and an objective reality. Second is the concept of reason, (...) which in the context of science obligates practitioners to justify their claims to others with reasons by grounding them in beliefs that are universally shared within the community. Third is the concept of social norm, which is not primarily epistemic, but provides children with an understanding of norms as collective agreements. The theoretical argument is that all three of these concepts emerge not from just any kind of social interaction, but specifically from social interactions structured by the human species’ unique capacities for shared intentionality.

Rational agency is of central interest to philosophy, with evolutionary accounts of the cognitive underpinnings of rational agency being much debated. Yet one building block—our ability to argue—is less studied, except Mercier and Sperber’s argumentative theory :57–74, https://doi.org/10.1017/s0140525x10000968, 2011, in The enigma of reason. Harvard University Press, Cambridge, 2017). I discuss their account and argue that it faces a lacuna: It cannot explain the origin of argumentation as a series of small steps that reveal how hominins with baseline abilities of (...) the trait in question could turn into full-blown owners of it. This paper then provides a first sketch of the desired evolutionary trajectory. I argue that reasoning coevolves with the ability to coordinate behavior. After that, I establish a model based on niche construction theory. This model yields a story with following claims. First, argumentation came into being during the Oldowan period as a tool for justifying information ‘out of sight’. Second, argumentation enabled hominins to solve collective action problems with collaborators out of sight, which stabilized argumentative practices eventually. Archeological findings are discussed to substantiate both claims. I conclude with outlining changes resultant from my model for the concept of rational agency. (shrink)
