Famous quotes containing the words signet, ring and/or cell:
“Commerce has set the mark of selfishness,
The signet of its all-enslaving power,
Upon a shining ore, and called it gold:
Before whose image bow the vulgar great,
The vainly rich, the miserable proud,
The mob of peasants, nobles, priests, and kings,
And with blind feelings reverence the power
That grinds them to the dust of misery.”
—Percy Bysshe Shelley (1792–1822)
“When the merry bells ring round,
And the jocund rebecks sound
To many a youth and many a maid,
Dancing in the chequered shade;
And young and old come forth to play
On a sunshine holiday,”
—John Milton (1608–1674)
“Let man consider what he is in comparison with all existence; let him regard himself as lost in this remote corner of nature; and from the little cell in which he finds himself lodged, I mean the universe, let him estimate at their true value the earth, kingdoms, cities, and himself. What is a man in the infinite?”
—Blaise Pascal (1623–1662)
