The concept that personal myths shape individual behavior in a manner
that is analogous to the way cultural myths influence social behavior
has been gaining increasing attention over the past two decades. A per
sonal mythology is an internalized model of reality that is composed o
f postulates about oneself, one's world, and the relationship between
the two. These postulates, which address immediate as well as eternal
concerns, are both descriptive (furnishing explanations) and instructi
ve (generating motivation). A comprehensive theory of human developmen
t that is based on the individual's evolving mythology integrates the
biological, psychodynamic, cultural, and spiritual dimensions of exper
ience. This article expands the personal mythology construct, suggesti
ng that personal myths function not only as biochemically coded models
of reality but also as fields of information-natural although nonvisi
ble elements of the physical universe-that affect consciousness and be
havior. Just as some neurologists have proposed that ''mental fields''
complement brain activity in unifying experience and some biologists
have proposed that ''morphic fields'' complement the action of the gen
e in giving form to an organism, the current work proposes that mythic
fields complement the physiological bases of consciousness in storing
symbolic content and maintaining psychological habits. Implications o
f this formulation for personal and social change are considered.
