  The most salient feature of infinite modes is that they are more directly related to substance than finite modes are. Spinoza claims that infinite modes follow more or less directly from “the absolute nature of any of God’s attributes,” whereas finite modes do not follow from the absolute nature of God’s attributes (see Ip21–22 and Ip28d). According to some interpreters, understanding this distinction is the key to understanding whether or not Spinoza was a full-blown necessitarian.
