Reading theory is quite an experience. It requires a lot from me and I imagine from many others. It takes some effort but it is very giving, and at times inspiring. When I finally begin to get some clue about the author’s line of thought I tend to get strange and contradictory signals: clear images come sometimes, answers to old puzzles at others, and usually many questions. It moves me to want to read and know more.
Habermas' article is good and substantial reading that opens windows and illuminates some holes accumulated in the room of my ignorance.
