Three great sages on talking to oneself

Point: CS Lewis in chapter VIII of A Preface to Paradise Lost, writing of self-referential and -reverential modern “poetry which exists only for the poet”:

 
There is nothing especially admirable in talking to oneself. Indeed, it is arguable that Himself is the very audience before whom a man postures most and on whom he practises the most elaborate deceptions.
 

Counterpoint: GK Chesterton in a tongue-in-cheek review of his own short comedy play Magic, a quotation I once shared in the very early days of this blog:

 
If a man does not talk to himself, it is because he is not worth talking to.
 

Case study for your consideration: This exchange from “Tankin’ it to the Streets,” an episode from season six of “King of the Hill”:

 
Hank: You know, Dale, sometimes I think you say things just to hear yourself talk.
Dale: What do you want me to do, ignore myself?
 

Project for synthesis: In what ways is Dale Gribble A) the self-deceived man described by Lewis and B) a man worth talking to, as described by Chesterton? Is he either A or B or both A and B? Is he B despite or because of A?
