I always liked the Robertson Davies line that consistency was a virtue for tiny minds. Stumbled across two more quotes in a similar vein and think I might try putting them up as a display in a classroom.
“Do I contradict myself? Very well then, I contradict myself. I am large, I contain multitudes”
– Walt Whitman.
“The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time and still retain the ability to function.”
– F. Scott Fitzgerald.
