This video features an excellent talk by philosopher Peter S. Williams regarding the existence of God, the limits of science and some of the arguments made by the so-called "new atheists" such as Lawrence Krauss and Richard Dawkins.
I encourage viewers not only to assess the arguments and evidence presented by Williams, but also take note of the manner in which he delivers this talk. He presents his arguments clearly, represents his opponents fairly, and his conclusions are modest. This is evident throughout. Apologists or those who simply desire to present their arguments more persuasively would do well to learn from Williams and model his approach.
Courage and Godspeed,
