“Deep with the first dead lies London’s daughter,
Robed in the long friends,
The grains beyond age, the dark veins of her mother,
Secret by the unmourning water
Of the riding Thames.
After the first death, there is no other.”
—Dylan Thomas (1914–1953)
“What does it matter how one comes by the truth so long as one pounces upon it and lives by it?”
—Henry Miller (1891–1980)
