I think a person is open-minded about some issue if she identifies her assumptions and opinions about the issue and is willing to subject her assumptions and her opinions to critical inquiry.
— Gregory Ganssle, from Thinking About God: First Steps in Philosophy, p. 36
Once our minds are open to open-mindedness, all ideas, no matter how absurd, can come and go as they please—with our sanction. We thus become headless and brainless philosophers who just want to get along.
— Burk Parsons, from ‘Don’t Be So Open-Minded’ in Tabletalk, June 2008
