Mehdi Hasan, who hosts The Mehdi Hasan Show on MSNBC, is known as one of the most formidable interviewers in journalism. He has tangled with Blackwater's Erik Prince, John Bolton, Richard Dawkins, Paul Bremer, and many others. A video of a powerful speech he gave defending Islam at Oxford University has received 10 million views. He has now written a book on his methods, Win Every Argument: The Art of Debating, Persuading, and Public Speaking, showing how to effectively confront and expose toxic beliefs. In this high energy conversation, he joins to discuss such questions as: Is debate "worth it"? Can it actually accomplish anything?What beliefs are not worth debating? How do you decide what to "legitimize"?Should Mehdi have Marjorie Taylor Greene on his program? (Nathan thinks so. Mehdi very much does not.)Are "ad hominem" attacks illegitimate? Or are they legitimate? When is it fair to use "rhetoric" over "reason"?“Philosophically, I consider argument and debate to be the lifeblood of democracy, as well as the only surefire way to establish the truth. Arguments can help us solve problems, uncover ideas we would’ve never considered, and hurry our disagreements toward (even begrudging) understanding. There are also patent practical benefits to knowing how to argue and speak in public. These are vital soft skills that allow you to advance in your career and improve your lot in life. There are very few things you cannot achieve when you have the skill and ability to change people’s minds.” — Mehdi Hasan Listen to Mehdi Hasan's previous appearance on the Current Affairs podcast here.
