Out of all the people world, and especially the intellectuals, I consider Alvin Plantinga one of the best. He has authored numerous Christian books from reformed epistemology to God, Freedom and Evil. Thorough and investigative, his books cover major topics in apologetics and theology that are especially controversial (i.e. theodicy) as he makes every attempt to answer them rationally.

He has also debated the likes of Daniel Dennett and Quinten Smith–both of whom are top philosophers and atheists in modern times. Certainly, Plantinga has many reasons to be considered a top intellectual of today.
