Prominent evolutionary psychologists have argued that our innate psychological endowment consists of numerous domainspecific cognitive resources, rather than a few domaingeneral ones. In the light of some conceptual clarification, we examine the central inprinciple arguments that evolutionary psychologists mount against domaingeneral cognition. We conclude (a) that the fundamental logic of Darwinism, as advanced within evolutionary psychology, does not entail that the innate mind consists exclusively, or even massively, of domainspecific features, and (b) that a mixed innate cognitive economy of domainspecific (...) and domaingeneral resources remains a genuine conceptual possibility. However, an examination of evolutionary psychology's 'grain problem' reveals that there is no way of establishing a principled and robust distinction between domainspecific and domaingeneral features. Nevertheless, we show that evolutionary psychologists can and do live with this grain problem without their whole enterprise being undermined. (shrink)

In this paper, we outline a theory of the nature of self-directed agents. What is distinctive about self-directed agents is their ability to anticipate interaction processes and to evaluate their performance, and thus their sensitivity to context. They can improve performance relative to goals, and can, in certain instances, construct new goals. We contrast self-directedness with reactive action processes that are not modifiable by the agent, though they may be modified by supra-agent processes such as populational adaptation or external design.Self-directedness (...) lies at the nexus of issues concerning the evolution and nature of intentionality, intelligence, and agency. It provides some insight into the evolution of intelligence because it helps explain how organisms are able to manage variable interaction processes, e.g., a hunting strategy that varies with prey type, ground condition, and hunger level. Simple self-directed organisms like bumblebees manage variability in one or a few dimensions. (shrink)
