Somewhat OT and somewhat not, this link goes to Walker Percy's last 
public address before his death. "The San Andreas Fault in the Modern 
Mind" touches on some things that have been discussed here. Its primary 
focus is Percy's claim that "we do not have even the rudiments of a 
science of man." Of Freud and Darwin, he notes that both were attacked 
in their own time for being too radical, but both it turns out were not 
radical enough: neither could explain his own activities by his own 
theories. Percy goes on to introduce Charles Peirce and semiotics, the 
science of signs. Percy, a trained physician, discusses complicated 
thought and subjects in plain English.
