Could you please provide more information on the Popper and Adams
references you cite above? While I'm fairly certain that Popper
1979 is:
Popper, Karl. Objective knowledge: an evolutionary approach. Oxford:
Oxford University Press; 1979,
I've had a bit of trouble searching for the Adams reference. It
appears that Douglas Adams published "The Hitchhiker's Guide to the
Galaxy" in 1979, and as a result of that work's popularity there's
almost no hope of using a general search engine to find a different
"Adams D 1979".
On the other hand, the context of the citation:
Knut> that depends entirely on your ability to understand what the
Knut> underlying question would be (see Adams D 1979)
leads me to suspect that you intended to cite The Hitchhikker's
Guide.
Cheers,
Andy
