What is real is no longer a question for philosophers alone. In today's world, it's a question we all contend with on a daily basis. Online, on television, in print and in public discourse, facts, feelings, and flat-out lies all share the same stage.

So how are we to tell the difference? Experts in technology, media, education, science, and politics are debating this very question. And while possible solutions are in the works, the truth may be that we as people simply prefer a lie that feels good over a truth that doesn't. Is the real problem our own human nature?

This hour we discuss not only the present and future of fake news, but its history as well. Turns out that efforts to undermine the truth are nearly as old as truth itself.
