 In the Poetics (1447a), Aristotle makes clear that all the arts are imitative, although they differ in the means, object, and manner of imitation. Aristotle has a more positive view of imitation than Plato, observing that humans are prone to it since childhood, and granting that we may learn through imitation. This cognitive value of imitations also explains why we feel pleasure when engaging with them, even when they imitate things we would find ugly or repulsive in real life (Poetics, 1448b 5–20).
