What is Poetry? — Poetry! that Proteus-like idea, with as many appellations as the nine-titled Corcyra! [Corfu] “Give me,” I demanded of a scholar some time ago, “give me a definition of poetry?” “Très-volontiers;” and he proceeded to his library, brought me a Dr. Johnson, and overwhelmed me with a definition. Shade of the immortal Shakespeare! I imagined to myself the scowl of your spiritual eye upon the profanity of that scurrilous Ursa Major. Think of poetry, dear B——, think of poetry, and then think of Dr. Samuel Johnson! Think of all that is airy and fairy-like, and then of all that is hideous and unwieldy; think of his huge bulk, the Elephant! and then—and then think of the Tempest—the Midsummer Night’s Dream— Prospero —Oberon—and Titania!
Though Hamlet's "To be or not to be" speech is his fourth soliloquy, many websites call it his third. They're skipping the twenty-line speech that follows his interview with the Ghost, which in my view is a particularly bad mistake since Hamlet's monomaniacal vow there is at the heart of his tragedy. The internet's cosmic sinkhole of misinformation will never be filled, but it's worth throwing some dirt in when we can, so here's an accurate list of Hamlet's soliloquies, with a short description of where they occur and what they say, along with a few observations.
