Roy Sorenson, Washington University philosophy professor, boggles our minds with riddles, puzzles and mind-bending tricks on "St. Louis on the Air."

Washington University philosophy professor Roy Sorensen knows your true philosophical quandary: ‘Which came first, the chicken or the egg?’ We asked him to answer this question and share some of his trickiest puzzles, riddles and audio mysteries for our listeners to sort through on Monday’s St. Louis on the Air.

“I’m an egg man myself,” Sorensen said. Not all of you agreed, however.

Sorensen is the author of “A Cabinet of Philosophical Curiosities: A Collection of Puzzles, Oddities, Riddles and Dilemmas,” which was released earlier this year. Listen to him describe the puzzles and dilemmas that interest him most:

This is what is known as a semantic slip.  Read more about that here.
