“Some would find fault with the morning red, if they ever got up early enough.”
—Henry David Thoreau (1817–1862)
“... the modern drama, operating through the double channel of dramatist and interpreter, affecting as it does both mind and heart, is the strongest force in developing social discontent, swelling the powerful tide of unrest that sweeps onward and over the dam of ignorance, prejudice, and superstition.”
—Emma Goldman (1869–1940)
“Of all the barbarous middle ages, that
Which is most barbarous is the middle age
Of man! it is—I really scarce know what;
But when we hover between fool and sage,
And don’t know justly what we would be at—
A period something like a printed page,
Black letter upon foolscap, while our hair
Grows grizzled, and we are not what we were.”
—George Gordon Noel Byron (1788–1824)
