Famous quotes containing the words air and/or pump:
“To be worst,
The lowest and most dejected thing of fortune,
Stands still in esperance, lives not in fear.
The lamentable change is from the best;
The worst returns to laughter. Welcome, then,
Thou unsubstantial air that I embrace!
The wretch that thou hast blown unto the worst
Owes nothing to thy blasts.”
—William Shakespeare (1564–1616)
“God primes the pump of obligation.”
—A.P. Martinich (b. 1946)
