Speaking to the larger issue you raise, yes, anyone who thinks we are purely rational creatures is deluding themselves:
. . . they failed to appreciate that the self illusion explains so many aspects of human behavior as well as our attitudes toward others. When we judge others, we consider them responsible for their actions. But was Mary Bale, the bank worker from Coventry who was caught on video dropping a cat into a garbage can, being true to her self? Or was Mel Gibson’s drunken anti-Semitic rant being himself or under the influence of someone else? What motivated Congressman Weiner to text naked pictures of himself to women he did not know? In the book, I consider some of the extremes of human behavior from mass murderers with brain tumors that may have made them kill, to rising politicians who self-destruct. By rejecting the notion of a core self and considering how we are a multitude of competing urges and impulses, I think it is easier to understand why we suddenly go off the rails. It explains why we act, often unconsciously, in a way that is inconsistent with our self image – or the image of our self as we believe others see us.
That said, the self illusion is probably an inescapable experience we need for interacting with others and the world, and indeed we cannot readily abandon or ignore its influence, but we should be skeptical that each of us is the coherent, integrated entity we assume we are.
