There is also no account of free word order phenomena, characteristic of many languages of the world.
Fourth, the details of the recursive structures are largely arbitrary and learned, conforming to the words and constructions of the linguistic community, rather than being dictated by immediate real-world constraints such as how a scene is put together or which sequence of actions is physically capable of effecting a goal.
It combines the key idea of the cognitive revolution of the 1950s and 1960s—that the mind is a computational system—with the key idea of the new evolutionary biology of the 1960s and 1970s—that signs of design in the natural world are products of the natural selection of replicating entities, namely genes.

And it differs from the claim that intelligence can be understood only by considering what mental states refer to in the world, or by examining the incarnate person embedded in a physical and social context.
Fodor emphasizes the idea that the representations in a computational system are syntactic: they are composed of parts in some arrangement, and the causal mechanisms of the system are sensitive to the identity and arrangement of those parts rather than to what they refer to in the world.
Our affective repertoire comprises emotions pertaining to the physical world, such as fear and disgust, and emotions pertaining to the social and moral worlds, such as trust, sympathy, gratitude, guilt, anger, and humor.
