The myths of a culture are its central stories. These stories provide a dramatic record of the historically predicated transformation of human intent, and appear to exist as the episodic/semantic embodiment of history’s cumulative effect on action.
The mythical narratives that accompany retention of historically determined behavior constitute non-empirical episodic representation of that behavior and its method of establishment. Myth is purpose, coded in episodic memory. Mythic truth is information, derived from past experience – derived from past observation of behavior – relevant from the perspective of fundamental motivation and effect.
Myth simultaneously provides a record of historical essential, in terms of behavior, and programs those historical essentials. Narrative provides semantic description of action in image, back translatable into imaginary episodic events, capable of eliciting imitative behavior.
Mythic narrative offers dramatic presentation of morality, which is the study of what should be. Such narrative concerns itself with the meaning of the past, with the implications of past existence for current and future activity. This meeting constitutes the ground for the organization of behavior.
Myth has come to encapsulate and express the essential nature of the exploratory, creative, communicative psyche, as manifested in behavior, as a consequence of observation and representation of that behavior, in the temporally summed, historically determined manner beginning with imitation and ending with verbal abstraction.
