John Maurice Clark is widely quoted as saying (or having written), 
"An irrational passion for dispassionate rationality will take the 
joy out of life."  The quote is often abbreviated, with the "will 
take the joy out of life" being left off and with the first part said 
to define an economist.

I've spent a good deal of time trying to track down the source, going 
through pages of Internet hits, but I've never seen the source 
given.  Would someone on this list give me the source or, perhaps, 
some direction on my search.  I'm trying to track down the source 
because I am working on a book on the evolution of rationality in 
economics, with some attention to how modern neuroscience/biology can 
speak to the limits of rationality.

Thanks in advance.
