Pinker has written about cognitive science and language at every level from the most technical to the approachable level of popular science. He is most noted for his work on how children acquire language and for his furthering of Noam Chomsky's work on language as a basic human instinct.
Pinker is not alone in seeing a complete denial of human nature in the academic left, or arguing that this is harmful. Ehrenreich and McIntosh, for example, suggest that postmodernism is the "new creationism", the newest threat to biology's explanations in terms of evolution. Pinker is often mentioned in the same breath as evolutionary psychologists such as Leda Cosmides and John Tooby, and would seem to share their commitment to using Darwin's theory of evolution by natural selection as a basis for understanding human behaviour.
