Famous quotes containing the words free, open and/or source:
“No man hath any quarrel to me. My remembrance is very free and clear from any image of offence done to any man.”
—William Shakespeare (1564–1616)
“Let a man learn to look for the permanent in the mutable and fleeting; let him learn to bear the disappearance of things he was wont to reverence; without losing his reverence; let him learn that he is here, not to work, but to be worked upon; and that, though abyss open under abyss, and opinion displace opinion, all are at last contained in the Eternal Cause.”
—Ralph Waldo Emerson (1803–1882)
“The belief in a supernatural source of evil is not necessary; men alone are quite capable of every wickedness.”
—Joseph Conrad (1857–1924)
