Laurie and I own a 1988 Volkswagen Quantum Syncro (just like this one, only not as nice). During a rainstorm this weekend, water got into the left-side headlight assembly and blew the bulb. Looking online for some information about fixing it, I discovered that the repair manual for our car was co-authored by none other than Jurgen Habermas, sociologist, philosopher and (until now) unacknowledged car mechanic extraordinaire. Several reviews of the book on Amazon confirm that this is a superb “application of the theory of communicative action to issues of automobile maintenance” and argue that it is “Habermas’s answer to Zen and the Art of Motorcycle Maintenance.” How fantastically appropriate that he should have written the manual for a car jointly owned and driven by a sociologist and a philosopher.
