"The history of science shows that great innovations violate established rules."

"We should examine whether our institutions truly serve human flourishing."

"Reason without imagination is sterile."

"The pursuit of universal principles often blinds us to particular truths."

"Dialogue requires listening, not merely waiting to speak."
