Factpinions Quote #5: Aristotle on Seeing Both Sides of the Question

In Aristotle's On Rhetoric, he wrote this pearl – as true today as it was 2300 years ago:

"We must be able to employ persuasion – just as strict reasoning can be employed – on opposite sides of a question, not in order that we may in practice employ it in both ways (for we must not make people believe what is wrong), but in order that we may see clearly what the facts are, and that, if another man argues unfairly, we on our part may be able to confute him."

– Aristotle, On Rhetoric I, 1, ca. 322 B.C., OUP 1954 edition.
