Famous quotes containing the words dark and/or matter:
“Even such is Time, which takes in trust
Our youth, our joys, and all we have,
And pays us but with age and dust,
Who in the dark and silent grave
When we have wandered all our ways
Shuts up the story of our days.
And from which earth, and grave, and dust,
The Lord shall raise me up I trust.”
—Sir Walter Raleigh (1552–1618)
“If human beings are immortal, so are animals. If matter has the ability to remember, it also has the ability to think.”
—Franz Grillparzer (1791–1872)
