 Although much of the philosophical discussion of concept nativism has focused on Fodor’s radical concept nativism, it is important to note that other less radical approaches to the origins of concepts exist and that these other approaches embrace a fair amount of learning—they just hold that much of this learning is structured by innate special-purpose acquisition systems (for example, Gallistel 1990, Keil 1989, Spelke &amp; Newport 1998, Baillargeon 2008, Carey 2009, Margolis &amp; Laurence 2013, Tooby &amp; Cosmides 2016).
