With what right do governments make and enforce laws? To what extent are citizens obligated to obey the law, even if a law is unjust? John and Ken talk about philosophy and the law with Jules Coleman from Yale University.

The pursuit of truth is often thought to be "intrinsically" valuable. Scientists and philosophers, who eschew religious rationales for their life's work, take the pursuit of truth to be obviously a worthwhile enterprise. But what's so great about truth? Sure, it's good to know what's for lunch, or the nature of the disease that plagues you, but is there any intrinsic or instrumental value in knowing how far away the farthest stars are? Or whether Milton's greatest works were written while he had a headache? Or what the next layer of basic particles are like? Truth telling on Philosophy Talk with Simon Blackburn, author of "Truth: A Guide."

Taking human life is wrong. But what if it is one's own life? Is suicide worse or less bad than murder? Is it wrong at all? Can suicide be rational? How about helping another commit suicide? The Philosophers discuss the metaphysics and morality of taking one's own life with Michael Cholbi from Cal Poly Pomona, author of "Suicide: The Philosophical Dimensions."

Plato claimed that numbers exist in some mind-independent abstract heaven. Nominalists claim that there is no such heaven. Clearly, we can't see, hear, taste or feel numbers. But if there are no numbers what is mathematics all about? John and Ken count on a great discussion with Gideon Rosen from Princeton University, co-author of "A Subject With No Object: Strategies for Nominalistic Interpretation of Mathematics."

Being funny isn't easy. Figuring out what makes things funny is even harder. Still, a number of psychologists (e.g., Freud) and philosophers (e.g., Bergson) have tried. Now computer scientists are trying to learn enough about humor to construct programs that can write good jokes; maybe an artificial stand-up comedian is on the way. Ken and John discuss the art, philosophy and science of humor with Tony Veale, an Irish computer scientist who knows a good joke when his program produces one.
