Final answer:
Aristotle emphasized the importance of individual instances or particulars, arguing that without them, there could be no knowledge of the form. He believed that individual instances, such as beautiful things like flowers and faces, are necessary to understand abstract concepts like beauty.
Step-by-step explanation:
Aristotle argued in favor of individualism by emphasizing the importance of individual instances or particulars. While Plato believed that forms were the true essence and that individual instances were mere reflections of these forms, Aristotle believed that without individual instances, there could be no knowledge of the form. For example, while Plato held that beauty itself causes the beauty we see in flowers or faces, Aristotle asserted that there is no such thing as beauty without beautiful things, such as flowers and faces.
