In my opinion, J. Budziszewski (pronounced Boojee-shef-ski), professor of Government and Philosophy at the University of Texas in Austin, is one of the better writers and thinkers of our time. He is one of those rare individuals whose every article or book--whether you agree with him or not--is worth reading.
Budziszewski was recently interviewed by Peter Hastie of the Australian Presbyterian magazine on the subject of natural law. (Scroll down to pages 4-8 of the PDF.)
