 In recent years, the debate over innate concepts has been reinvigorated as advances in cognitive science have provided philosophers with new tools for revisiting and refining the traditional dispute (see, e.g., Elman et al. 1996, Carruthers, Laurence, &amp; Stich 2005, 2006, 2007, Johnson 2010). Philosophers have greatly benefited from empirical studies in such diverse fields as developmental psychology, evolutionary psychology, cognitive anthropology, neuroscience, linguistics, and ethology. Part of the philosophical interest of this work is that, while the scientists themselves take sides on the empiricist-nativist dispute, their theories and data are often open to interpretation.
