I would have to say that in my experience , all humans suffer from a certain level of self delusion.Hey its normal.From the man who will never admit he's wrong, the croaky singer who thinks she's a opera star , the "model" with the looks of the back end of a pig, and JW's who are the only true religion.
So do we have an in built self delusion programe?Is it helpful in anyway to delude overslves as to our weeknesses?
Maybe being constantly aware of all our faults would be too much for us to handle,causing us to go bananas.Our brain may need to introduce a level of stability in our lives and wont let us be "weak'nd" by discovering we belive a false piece of information our idea about ourself that if revealed to the conscious mind could causes severe disruption to our lives.Prehaps pride is the bodies weapon against stress caused by negative truths.
Any thoughts?
