Famous quotes containing the words dark and/or matter:
“A man growing old is going
down the dark stairs.
He has been speaking of the Soul
tattooed with the Law.
Of dreams
burnt in the bone.”

“I have heard arguments ... in favor of pardoning D. M. Bennett, convicted of sending obscene matter through the mails, viz., a pamphlet [by Ezra Hervey Heywood] of a polemical character in favor of free love. While I am satisfied that Bennett ought not to have been convicted, I am not satisfied that I ought to undertake to correct the mistakes of the courts—constantly persisted in—by the exercise of the pardoning power.”
—Rutherford Birchard Hayes (1822–1893)
