I don't have the 1994 edition of Road to Serfdom on my shelf, so cannot   
respond to the two page references Andrew offers. I have read the Road to   
Serdom, though, and I stand by my suggestion that the slippery slope   
argument, often attributed to Hayek by friends (Stigler, Robbins) and   
critics (Samuelson, Wootton) alike, is not what he actually said.  I have   
offered my arguments in the paper Andrew cites in the European journal,   
and also in my editor's introduction to the new edition of The Road to   
Serfdom that is being published by The Collected Works. I invite those   
interested to read those.   
  
I concede that the Look cartoon version is perhaps consistent with   
Andrew's argument. I also think that the Reader's digest condensed version   
is. This may help us to understand how such misreadings can occur. What   
Hayek's 1983 address, The Muddle in the Middle has to do with the argument   
in the Road to Serfdom, which is what we were talking about, is unclear to   
me.
