Note 317 — Chapter III · THE INFINITE UNIVERSE—THE MIRROR OF GOD[289]

De Imm. bk. i. ch. 10. pp. 235–8; cf. Infinito, 312 f., 316. Bruno does not use the term “principle of sufficient reason”: his principle is the inverse of that of Leibniz—“whatever has not a sufficient reason for existing is necessarily non-existent,”—Bruno’s being that “whatever has not a sufficient reason for non-existence (i.e. whatever is possible) necessarily exists.”
