I am reminded of that momentous debate Bertrand Russell had with Frederick Copelston in BBC radio back in the 1940s, Copleston, as a Thomist and Neo-Aristotelean was arguing about the origin of the universe, that a First Cause must have caused the universe's birth which itself is uncaused (an argument I remember well reading Aquinas) because a material causality that goes Ad Infinitum is a logical contradiction, Lord Russell did not engage him saying that the Universe has always been in existence, it has always been there with no beginning, Copelstone replied "Lord Russell,discussing the beginning of the universe with someone who believes it didn't have a beginning then it would be a very difficult topic to discuss wouldn't you say so?" Russell replied "Yes... very difficult... Can we switch to another topic then" reading about Cosmology and the Big Bang Theory, I always smiled and remembered that debate, if only Russell lived long enough to see that Science has proven that the Universe indeed have a beginning. *_*
