Berger, Peter. "What Happens When a Leftist Philosopher Discovers God?" The American Interest. Septermber 21, 2011.

Excerpt:

Habermas is exactly my age. Our paths crossed briefly in the 1960s, when he was a visiting professor in the Graduate Faculty of the New School for Social Research, where I was then teaching. We did not particularly take to each other. I was put off by both his leftist politics and his ponderous philosophical language. (German philosophers, no matter where located on the ideological spectrum, vie with each other in producing texts which are comprehensible only to a small group of initiates.) I also sensed a certain professorial arrogance. I remember reading a response by Habermas to a critic, limited to the statement that he refused to discuss with an individual who quoted Hegel from a secondary source.
