1. 1. The spatialization of time goes back to Aristotle. See Corish, “Aristotle’s,” “Aristotle.”
2. 2. Hume repudiates the Treatise in the “Advertisement” of the first section of An Enquiry Concerning Human Understanding (83). However, even though there is no theory of time, space, succession, or extension as such in the first section of An Enquiry Concerning Human Understanding, the few passing mentions of these topics in the later work (e.g., 7.6–8, 12.18–19) are consistent with what he says about them in the Treatise. Unless otherwise noted, citations from Hume are from the Treatise.
3. 3. Corish, “Continuum” 535n30. Despite Corish’s assertion that the temporal continuum is relational, divisible, and measurable, the main thrust of his paper is not Humean, but Leibnizian, quoting Leibniz favorably as to the preexistent reality of space and time (“Continuum,” 523).
4. 4. McTaggart, Nature, vol. 2, ch. 33; “Unreality” 9–31. That McTaggart does not mention Hume in this chapter is odd. See Gale; also Corish, “McTaggart’s,” “Time,” and “Earlier.”
5. 5. Hume (Treatise 1.2.4.1–2, 1.2.5.29) and McTaggart (Nature 11–12) are each quite clear on this point. See Corish, “Could.”
