Quotes from Frank M. Dattilio

Millon and Davis analogize the personality as one's psychological immune system.

The personality, in effect, is made up of one's coping repertoire and ability to adapt and therefore creates immunity to invading stressors or, in keeping with the analogy, bacteria. Throughout development, one faces crises and challenges. As development occurs, the system learns to respond, shift, adapt, and cope. However, if the system is overwhelmed by stressors insurmountable to the existing coping system, the system cannot effectively manage.
