Famous quotes containing the words pro and/or logic:
“It is sweet and honourable to die for one’s country.
[Dulce et decorum est pro patria mori.]”
—Horace [Quintus Horatius Flaccus] (65–8 B.C.)
“Though living is a dreadful thing
And a dreadful thing is it
Life the niggard will not thank,
She will not teach who will not sing,
And what serves, on the final bank,
Our logic and our wit?”
—Philip Larkin (1922–1986)
