I have a bit of a love / hate relationship with this book. It is somewhat tedious, but necessary tediousness to suit the author's purpose.
Philosophers have been perplexed by the phenomenon of self deception, which seems as though it should be logically impossible. How can the same person be both the deceiver and deceived, hiding from himself that which he really believes, and hiding the knowledge of the hiding? Such brain twisters are the stuff of pages and pages of analysis and debate.
Ultimately, the author proffers a coherent account that appears to solve the dilemma. He insists that the self deceived person can be sincere, but that he is nevertheless responsible, for he should see through his own ruse. He avoids the truth by giving attention to what he desires, while refusing to give attention to that which might expose the truth.
Quote: "The self-deceiver has come to a belief which he dreads, cannot face up to, or wishes were otherwise since it brings some unpleasant truth (as he perceives it) before him."
Therefore the reason he does this is to avoid pain or guilt. The author points to the ubiquity of this phenomenon to which all human beings are subject. We fancy ourselves consistently rational and logical while the reality is anything but.
Good food for thought but not a book everyone will enjoy. It's certainly not the easiest read.
