Abstract

MORE THAN MOST PHILOSOPHERS, Spinoza needed a coherent and sophisticated set of views on the nature of possibility: many of his most important philosophical positions and arguments depended on it. As one example, take Ethics IP33. This Proposition—among the most famous of the Ethics— states, “Things could have been produced by God in no other way, and in no other order than they have been produced.” In a salutary attempt to clarify the meaning of IP33 et relata, Spinoza adds in the first Scholium to IP33 that “by these propositions I have shown more clearly than the noon light that there is absolutely nothing in things on account of which they can be called contingent.” Now, such assertions were bound to give rise to numerous objections and Spinoza knew it. To meet these objections, he immediately proceeds to one of the most powerful: namely, are there not things that actually have been “produced by God” that need not have been “produced by God?” And would it not make sense to call these things “contingent or possible?” In reply, Spinoza reinterprets the concept of possibility. We call existing things “contingent” “only because of a defect of our knowledge.” There are, he continues, two types of deficiency that lead us to regard existing things as “contingent or possible”: either we do not know “that the thing’s essence involves a contradiction” or we do know that the thing’s essence does not involve a contradiction but we do not know enough about the “order of causes” to affirm anything “certainly about its existence.”
