 In more general terms, Spinoza’s idea is that possibilities are grounded in God by being actually exemplified by God, a view that fits nicely with interpretations of Spinoza’s modes as things that inhere in God (see section 1.3 above). Thus, it is possible for something to be thinking because God is actually a thinking thing (IIp1d). The grounding of possibility in actuality is a very attractive metaphysical thesis in its own right, and Spinoza’s God has a sufficiently rich nature to ground all possibilities by actually exemplifying them all (Ip15 and Ip16).
