"Schizophrenia, like the Unicorn, is described in various ways by
|
|
various people. And its elimination, like the capture of the Unicorn,
|
|
appears to require some special conditions, not all of which have yet
|
|
been specified. Finally, whether or not those conditions exist, belief
|
|
in their existence has had significant consequences."
