Abstract
The article examines the relation between two kinds of ontological relations that hold together the building blocks of Spinoza’s metaphysics: “being in” and “affection of.” It argues that in order to speak of existence in a single sense, Spinoza equivocates on the notion of affection. On the one hand, substance is in itself in the same sense that every other existing thing is in substance. On the other hand, substance is not the affections of itself, affections of substance are not related to substance in the same sense that affections of modes are related to modes, and affections of modes, which are affections of affections of substance, cannot, at least in some cases, be regarded as affections of substance. Thus, although “God is without passions,” the passions themselves exist in the same sense that God, human beings, and other modes exist, that is, in the sense that they are all in nature; but while the meaning of “being” remains the same, the meaning of “being affected,” or “feeling,” necessarily changes as the Ethics unfolds.
