"And let this always weigh down your feet like lead,
to make you move as slowly as a weary man,
to refrain from 'yes' or 'no' when you do not see ...
because hasty opinion too often
points the wrong way and then affection
for one's own opinion binds up the intellect."
Dante, Purgatorio XIII: 112-114, 118-120. He puts these words into the mouth of Thomas Aquinas, the thinker now purloined and abused by the theocons.
