Jungian Collective Unconcious

The reason to which there is a common manifestation of archetypes and morality across contrasting cultures is not the work of a metaphysical truism. Rather, it is the uprising of common behaviors in group cohesion and natural societal formation that is propelled by the intrinsic human nature within its inhabitants. Cultures and societies are all founded on the mutual agreement of human behavior. When a group has enough power, whatever is deemed as moral to them becomes moral. This is not to say most historical rulers were necessarily cruel, as harmful behavior towards one's people often leads to the overthrowing of the tyrant that rules over them. However due to the similarities between morality and other aspects of society that exist in cultures that never precedingly interacted, there has to be some paradigm that constitutes a society's nature. Many of the laws that a country upholds are based on this fundamental understanding of psychology. For example, empathy facilitates what is considered to be just without needing preceding ideologies to make that conclusion rational. 

Archetypes in cultural settings are produced through a similar manner. The hero is labeled as such because he saves someone (through his emotion of empathy) from danger. Or perhaps the hero sees a society in need of saving and finds its development valuable to the soul. The magician is also another naturally inclined archetype. Humans are intrinsically curious, even as babies we constantly ask “Why” and “How” while the amount of embodiment this archetype receives varies from individual to individual, regardless one can observe its existence in the psyche.

Mythology is hardly different, the personification of gods are crafted both by their environment as well as the psyche. Gods from different cultures have similar characteristics while their appearance or names may be completely different. For example, Zeus (Greek) who rules over lightning and thunder could have characteristics similar to Indra (Hindu) who also governs over lightning and thunder. Their divinity and metaphysicality can be reduced to the epistemological processing of the human psyche.

Symbolism is also similar. The field of psychoanalysis uses imagery to understand the workings of the unconscious, implying that it may be under influence of something otherworldly. Given the nuance of this field and its eroding of reliability in modern psychological practice, this is mainly considered inapplicable in treatment. Even so, when cases are in alignment with its divinatory means, the symbolism is not necessarily derived from a collective unconscious understanding of its symbols. Rather the symbols are often in alignment with previous associations with the imagery.
