Rick Wingrove, Robert Penczak and Robert Mendoza discuss  Christian Apologetics what it's about and why we as atheists should know something about it. (30 minutes)

Apologetics comes from the Greek apologia, "a speech in one's own defense". This from 1 Peter 3:15 (KJV)  "But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:" is the base for a tradition spanning from Paul to W. L. Craig and D. DeSouza. Attention is given to Thomas Aquinas' five foundational arguments for classical apologetics (motion, efficient cause, necessary being, gradation, design). Presuppositional apologetics, reformed epistemology and the transcendental argument for the existence of god are touched on. The atheist apologetics of Michael Martin (transcendental argument for the non-existence of god), François Tremblay and George H. Smith are discussed.
