 In a similar spirit, S. Shoemaker recently adapted Whitehead’s famous remark, observing that “the history of the topic of personal identity has been a series of footnotes to Locke” (2008: 313). It is certainly undeniable that no single discussion of personal identity has done more to shape the current debate than the chapter titled “Of Identity and Diversity” that Locke added to the second edition of his Essay Concerning Human Understanding (II.xxvii). (Hereafter, all textual references to  Locke are to this work, Locke 1689 [1975].) Also undeniable is the  effect these pages have had on the emergence of the animalist alternative to the Lockean approach to personal identity. For whatever intuitive appeal animalism may seem to have in our secular, post-Darwinian climate, in the wake of Locke’s work, the falsity of animalism was long taken for granted.
