Sonnet 18
Shall I compare thee to a summer's day?
The best-known poem in the English language — memorized by schoolchildren for centuries and quoted at more weddings than any other Shakespeare text.
What It Means
Shakespeare opens with what sounds like a compliment and immediately turns it into something more complex. Yes, he'll compare his friend to summer — but summer loses. Summer is too short, too rough, and unreliable. His friend is more temperate, more lovely, more consistent. The real turn comes in the sestet. It doesn't matter whether summer continues; this poem will. 'So long as men can breathe or eyes can see, / So long lives this, and this gives life to thee.' The poem is the argument. By writing it, Shakespeare is doing exactly what he promises — making his subject live forever. It's a statement of artistic confidence as much as a love poem.
