What is the scientific status and the "truth value" of the concept of defense mechanisms? Among contemporary psychologists, three types of answers to this question may be expected. Some would wholeheartedly endorse the theoretical, clinical, and research value of this notion; others would reject it outright. Between these two extremes, a large number of observers, perhaps the majority, would suspend their judgment. Their attitude, compounded of hope and doubt, would capitalize on defense as an interesting and promising concept. At the same time, these psy chologists would express skepticism and disappointment over its clinical limitations, theoretical ambiguity, and research failures. The present volume is primarily addressed to the audience of hopeful skeptics-those who have not given up on the notion of defense, yet have been frustrated by the difficulties of incorporating it into the modern, streamlined structure of psychology. To this end, we have brought together theoretical and empirical contributions germane to defense together with reports about their applications to clinical and personality assessment, especially in relation to psychopathology, psychosomatics, and psycho therapeutic intervention.

The idea that the human mind-that faculty of the intellect which we use to define and discern the truth-might also be used to deceive itself is not new. The classic orator Demosthenes warned of this possibility in 349 B.C. when he wrote that "Nothing is more easy than to deceive one's self; what a man wishes he generally believes to be true." 1 Even Jean Jacques Rousseau, who suggested the possibility of man as "noble savage," alerts us to this paradox, when he writes "Jamais fa nature ne nous trompe; c'est toujours nous qui nous trompons" ("Nature never deceives us; it is always we who deceive ourselves). 2 But it was Sigmund Freud who placed this idea firmly into the field of psychopathology and then, later, into a general psychological theory. According to Freud, understanding the function of a defense mechanism means not only fathoming the origin of pathological symptoms but also comprehending a model of the mind that includes both conscious and unconscious mental processes. From this initial focus on the general process of defense, Freud and his followers went on to identify various forms this process might take, with the result that today we have a list of 3 more than 37 defense mechanisms described in the literature.

Integrating theory, research, and applications, this book examines the defense mechanisms and their role in both normal development and psychopathology. It describes how children and adults mobilize specific kinds of defenses to maintain their psychological equilibrium and preserve self-esteem, particularly in situations of trauma or stress.

In 1964 a small group of African American men in Jonesboro, Louisiana, defied the nonviolence policy of the mainstream civil rights movement and formed an armed self-defense organization--the Deacons for Defense and Justice--to protect movement workers fr
