"The Recursive Mind: The Origins of Human Language, Thought, and Civilization, is a fascinating and well-grounded exposition of the nature and power of recursion. In its ultra-reasonable way, this is quite a revolutionary book because it attacks key notions about language and thought. Most notably, it disputes the idea, argued especially by linguist Noam Chomsky, that thought is fundamentally linguistic--in other words, you need language before you can have thoughts."--Liz Else, New Scientist
