Symbolic Self Completion [PDF ebook] 

First published in 1982. The problem addressed in this volume is the human pursuit of self-definitions. Self-definitions can vary widely with respect to the context in which they are found, and in regard to who aspires to possess them. Violinist, mother, humanitarian, intellectual, equestrian, and French-speaker are all examples of self-definitions.
