  2P7 and its scholium can be understood in very different ways. In what follows three types of interpretive directions are described. This is not meant to be exhaustive by any means, but it will provide a sense of the kinds of options that have been offered by commentators. Let us begin with the simplest option first. If one holds that there are only two attributes, Thought and Extension, the metaphysical structure of 2P7 and its scholium is quite straightforward. Every mode under the attribute of Thought is associated with a mode in Extension, and vice versa and the relations between modes in one attribute are mirrored in the other. Those that hold this kind of view must, of course, provide a convincing argument to the effect that there are only two attributes.
