Famous quotes containing the words external and/or links:
“A tempest cracked on the theatre. Quickly,
The wind beat in the roof and half the walls.
The ruin stood still in an external world.
It had been real. It was something overseas
That I remembered, something that I remembered
Overseas, that stood in an external world.”
—Wallace Stevens (1879–1955)
“My sister and I, you will recollect, were twins, and you know how subtle are the links which bind two souls which are so closely allied.”
—Sir Arthur Conan Doyle (1859–1930)
