This essay argues for a mixed-resource approach to scientific modeling and applies it to questions in philosophy of mind. A mixed-resource approach makes use of whatever resources-at whatever scale, from whatever academic discipline-seem useful, freely combining such varied resources in individual models. The success of mixed-resource modeling challenges the widely shared commitment to a personal level in the context of which mental states are to be studied in relative isolation. The adoption of a mixed-resource perspective has the potential to transform treatment of further matters in philosophy of mind, which is illustrated by discussion of psychological Frege cases.

These ten lectures articulate a distinctive vision of the structure and workings of the human mind, drawing from research on embodied cognition as well as from historically more entrenched approaches to the study of human thought. On the author’s view, multifarious materials co-contribute to the production of virtually all forms of human behavior, rendering implausible the idea that human action is best explained by processes taking place in an autonomous mental arena – those in the conscious mind or occurring at the so-called personal level. Rather, human behavior issues from a widely varied, though nevertheless integrated, collection of states and mechanisms, the integrated nature of which is determined by a form of clustering in the components’ contributions to the production of intelligent behavior. This package of resources, the cognitive system, is the human self. Among its elements, the cognitive system includes a vast number of representations, many subsets of which share their content. On the author’s view, redundancy of content itself constitutes an important explanatory quantity; the greater the extent of content-redundancy among representations that co-contribute to the production of an instance of behavior, the more fluid the behavior. In the course of developing and applying these views, the author addresses questions about the content of mental representations, extended cognition, the value of knowledge, and group minds.

This essay presents the conditional probability of co-contribution account of the individuation of cognitive systems (CPC) and argues that CPC provides an attractive basis for a theory of the cognitive self. The argument proceeds in a largely indirect way, by emphasizing empirical challenges faced by an approach that relies entirely on predictive processing (PP) mechanisms to ground a theory of the cognitive self. Given the challenges faced by PP-based approaches, we should prefer a theory of the cognitive self of the sort CPC offers, one that accommodates variety in the kinds of mechanism that, when integrated, constitute a cognitive system (and thus the cognitive self), to a theory according to which the cognitive self is composed of essentially one kind of thing, for instance, prediction-error minimization mechanisms. The final section focuses on one of the central functions of the cognitive self: to engage in conscious reasoning. It is argued that the phenomenon of conscious, deliberate reasoning poses an apparently insoluble problem for a PP-based view, one that seems to rest on a structural limitation of predictive-processing models. In a nutshell, conscious reasoning is a single-stream phenomenon, but, in order for PP to apply, two streams of activity must be involved, a prediction stream and an input stream. Thus, with regard to the question of the nature of the self, PP-based views must yield to an alternative approach, regardless of whether proponents of the predictive processing, as a comprehensive theory of cognition, can handle the various empirical challenges canvassed in the preceding section.

A vexing problem in contemporary epistemology—one with origins in Plato’s Meno —concerns the value of knowledge, and in particular, whether and how the value of knowledge exceeds the value of mere (unknown) true opinion. The recent literature is deeply divided on the matter of how best to address the problem. One point, however, remains unquestioned: that if a solution is to be found, it will be at the personal level, the level at which states of subjects or agents, as such, appear. We take exception to this orthodoxy, or at least to its unquestioned status. We argue that subpersonal states play a significant—arguably, primary—role in much epistemically relevant cognition and thus constitute a domain in which we might reasonably expect to locate the “missing source” of epistemic value, beyond the value attached to mere true belief.

It is often claimed that structured collections of individuals with mental or cognitive states-such collections as courts, countries, and corporations-have mental or cognitive states of their own.The existing critical literature casts substantial doubt on this claim.In this paper, I evaluate a defensive move made by some proponents of the view that groups have mental or cognitive states of their own: to concede that group states and individual states aren't of the same specific natural kinds, while holding that groups instantiate different species of mental or cognitive states-perhaps a different species of cognition it self-from those instantiated by humans.In order to evaluate this defense of group cognition, I present a view of natural kinds-or at least of the sort of evidence that supports inferences to sameness of natural kind-a view I have previously dubbed the 'tweak-andextend' theory, as well as a theory of cognitive systems.Guided by the tweak-and-extend approach, I arrive at a tentative conclusion: that what is common to models of individual cognitive processing and models of group processing does not suffice to establish sameness of cognitive (or mental) kinds, properties, or state-types across individuals and extant groups, not even at a generic level.

A theory of cognitive systems individuation is presented and defended. The approach has some affinity with Leonard Talmy’s Overlapping Systems Model of Cognitive Organization, and the paper’s first section explores aspects of Talmy’s view that are shared by the view developed herein. According to the view on offer – the conditional probability of co-contribution account (cpc) – a cognitive system is a collection of mechanisms that contribute, in overlapping subsets, to a wide variety of forms of intelligent behavior. Central to this approach is the idea of an integrated system. A formal characterization of integration is laid out in the form of a conditional-probability based measure of the clustering of causal contributors to the production of intelligent behavior. I relate the view to the debate over extended and embodied cognition and respond to objections that have been raised in print by Andy Clark, Colin Klein, and Felipe de Brigard.

This paper engages critically with anti-representationalist arguments pressed by prominent enactivists and their allies. The arguments in question are meant to show that the as-such and job-description problems constitute insurmountable challenges to causal-informational theories of mental content. In response to these challenges, a positive account of what makes a physical or computational structure a mental representation is proposed; the positive account is inspired partly by Dretske's views about content and partly by the role of mental representations in contemporary cognitive scientific modeling.
