 There are, however, differences in the way things depend on God. As an infinite being, God has infinite “attributes”. An attribute is best understood as a most basic way of being, a general nature that is expressed in determinate ways by particular things. We have knowledge of only two of these attributes: thought and extension. Some features of the universe follow necessarily from God—or, more precisely, from the absolute nature of one of God’s attributes—in a direct and unmediated manner. These are the universal and eternal aspects of the world, and they do not come into or go out of being; Spinoza calls them “infinite modes”. They include the most general principles of the universe, together governing all things in all ways. From the attribute of extension there follow the principles governing all extended objects (the truths of geometry) and laws governing the motion and rest of bodies (the laws of physics); from the attribute of thought, there follow laws of thought (understood by commentators to be either the laws of logic or the laws of psychology). Particular and individual things are causally more remote from God. They are nothing but “affections of God’s attributes, or modes by which God’s attributes are expressed in a certain and determinate way” (Ip25c). More precisely, they are finite modes.
