Abstract
The idea that some biological characteristics are innate, while controversial, is widespread in many academic disciplines. Neither philosophy nor science has outgrown the need to talk about traits, which, for a variety of reasons, appear to be inherent in biological populations. Philosophical claims of this nature are to be found in theories of moral sense, rational capacities, the way in which perception structures experience and so on. Scientific claims about innate traits are to be found in the study of animal behaviour and most famously in the relatively recent rise of nativism in cognitive science. In this tradition, Noam Chomsky and his heirs argue that much of our capacity to decipher verbal information is innate. David Marr defends a similar position with respect to the interpretation of visual information.
