In this essay, I argue that the God hypothesis is merely an idea based on a fantasy principle. Albeit a logical concept born of social convention, God is a semiotic embodiment and symbolization of ideal value. Put laconically, God is only a thought. Rather than an extant ontological subject or agency traditionally attributed to a supernatural, transcendent creator or supreme being responsible for the coming into being of the universe, God is a psychological invention signifying ultimate ideality. Here God becomes a self-relation to an internalized idealized object, the idealization of imagined value. This thesis partially rests on the psychoanalytic proposition that mental processes and contents of consciousness are grounded in an unconscious ontology that conditions the production of our conscious thoughts through fantasy formation. Although ideas have both conscious and unconscious origins, their articulation in consciousness is predicated on linguistic constructions governed by the psychodynamics of wish fulfillment based upon our primordial desires and conflicts. The idea or notion of God is the manifestation of our response to our being-in-relation-to-lack, and the longing to replace natural absence with divine presence. Hence God remains a deposit of one’s failure to mourn natural deprivation or lack in favor of the delusional belief in an ultimate hypostatized object of idealized value.
