The poetical character... is not itself — it has no self — it is every thing and nothing — It has no character — it enjoys light and shade; it lives in gusto, be it fair or foul, high or low, rich or poor, mean or elevated. — It has as much delight in conceiving an Iago as an Imogen. What shocks the virtuous philospher, delights the camelion poet.
