The following is a quote from Wikipedia
"Projection is the opposite defense mechanism to identification. We project our own unpleasant feelings onto someone else and blame them for having thoughts that we really have."
- "A defense mechanism in which the individual attributes to other people impulses and traits that he himself has but cannot accept. It is especially likely to occur when the person lacks insight into his own impulses and traits."
- "Attributing one's own undesirable traits to other people or agencies." The individual perceives in others the motive he denies having himself. Thus the cheat is sure that everyone else is dishonest."
- "People attribute their own undesirable traits onto others. An individual who possesses malicious characteristics, but who is unwilling to perceive himself as an antagonist, convinces himself that his opponent feels and would act the same way."
Projection is a primitive defense mechanism. Reason has no part of it. You can not be reasoned out of things into which you were not reasoned.
