 Our affects—our love, anger, hate, envy, pride, jealousy, etc.—“follow from the same necessity and force of nature as the other singular things”. Spinoza, therefore, explains these emotions—as determined in their occurrence as are a body in motion and the properties of a mathematical figure—just as he would explain any other things in nature. “I shall treat the nature and power of the Affects, and the power of the Mind over them, by the same Method by which, in the preceding parts, I treated God and the Mind, and I shall consider human actions and appetites just as if it were a Question of lines, planes, and bodies.”
