 This leaves us with an interpretive dilemma. On the one hand, Curley’s account respects both the demonstration of Ip28 and Spinoza’s frequent claims that all modes follow from God’s nature. A consequence of his account is that Spinoza is not a full-blown necessitarian. On the other hand, Curley’s Spinoza must reject very natural-sounding demands of the PSR. Spinoza would have to accept that there is no explanation why this entire series of finite modes exists rather than another possible series, a point Curley concedes (Curley and Walski, 1999).
