existieseis

Existieseis is a neologism used in speculative philosophy of mind and phenomenology to describe the process by which a conscious agent experiences, affirms, and communicates its own existence, as well as the existence of other entities, within a reflective or experiential framework. The term blends the sense of existence from the verb existere with the -esis suffix that marks processes or states.

Conceptually, existieseis is described as comprising two related phenomena. First, a pre-reflective, phenomenological sense of being present in the field of experience, often characterized as a basic givenness of presence. Second, a reflective or linguistic layer in which existence is instantiated, justified, or conveyed through assertions, demonstrations, or descriptions. Some theorists emphasize the distinction between an immediate felt presence (existential intuition) and the subsequent articulations that encode that presence for others.

The concept draws on strands of phenomenology, existentialism, and cognitive linguistics, and is sometimes used to analyze self-consciousness, embodied cognition, and the way presence is modeled in artificial systems. Advocates argue that existieseis helps illuminate how beings hedge between subjective experience and objective description, linking first-person certainty with external discourse. Critics contend that existieseis overlaps with established notions such as self-consciousness, ontology, and phenomenological givenness, offering limited added precision without standardized definitions or methods.
