The book from which these sections are excerpted is concerned with the prospects for assimilating the study of human intelligence and its products to the natural sciences through the investigation of cognitive structures, understood as systems of rules and representations that can be regarded as “mental organs.” These mental structui′es serve as the vehicles for the exercise of various capacities. They develop in the mind on the basis of an innate endowment that permits the growth of rich and highly articulated (...) structures along an intrinsically determined course under the triggering and partially shaping effect of experience, which fixes parameters in an intricate system of predetermined form. It is argued that the mind is modular in character, with a diversity of cognitive structures, each with its specific properties arid principles. Knowledge of language, of the behavior of objects, and much else crucially involves these mental structures, and is thus not characterizable in terms of capacities, dispositions, or practical abilities, nor is it necessarily grounded in experience in the standard sense of this term.Various types of knowledge and modes of knowledge acquisition are discussed in these terms. Some of the properties of the language faculty are investigated. The basic cognitive relation is “knowing a grammar”; knowledge of language is derivative and, correspondingly, raises further problems. Language as commonly understood is not a unitary phenomenon but involves a number of interacting systems: the “computational” system of grammar, which provides the representations of sound and meaning that permit a rich range of expressive potential, is distinct from a conceptual system with its own properties; knowledge of language must be distinguished from knowledge of how to use a language; and the various systems that enter into the knowledge and use of language must be further analyzed into their specific subcomponents.

If the central problem in philosophical ethics is determining and defining the scope of moral value, our normative ethical theories must be able to explain on what basis and to what extent entities have value. The scientific foundation of contemporary biosemiotic theory grounds a theory of moral value capable of addressing this problem. Namely, it suggests that what is morally relevant is semiosis. Within this framework, semiosis is a morally relevant and natural property of all living things thereby offering us (...) an ecological, as opposed to merely environmental, ethic. A consequence of this semiotic theory is that living things are accorded inherent moral value based on their natural relational properties—their ability to signify. This consequence establishes a hierarchy of inherent moral value based on the scope of signification: the larger the Umwelten, the greater the value. This paper argues that a robust semiotic moral theory can take into account a much wider scope of inherent value.. These consequences have positive ramifications for environmental ethics in their recognition of the natural ecological networks in which each organism is bound. This presentation of a biosemiotic model of value offers a justificatory strategy for our contemporary moral intuitions concerning our semiotic/moral relationships with living things while also productively pushing our normative ethical boundaries.

In this brief space I want to describe how Chomsky's analysis of "psychological reality" departs from what I think is a fairly standard construal of the idea. This familiar formulation arises from distinguishing between someone's following a rule and someone's acting in conformity with a rule. The former idea, but not the latter, involves the idea that the person has some mental representation of the rule that plays a certain causal role in determining behavior. Although there may be many grammatical (...) rules to which a person's verbal behavior (ignoring slips of the tongue and other performance interferences) conforms, only some of those rules have psychological reality; these are the ones that are internalized in thought and play some appropriate causal role.
