The article examines the relationship between the concepts of being, non-being, essence, non-subsistence, truth, lie and neutral ontological-epistemic status (possibility and probability). The difference between being and essence is the criterion of experience, but it allows us to distinguish only subjective being from essence as a composition of formal and material meanings. In addition to subjective being, or here-being, there is so-being, or the existential predicate of essence, which is an additional (in relation to the real predicate) meaning that does not add anything to the composition of formal and material meanings. Existential meaning is fixed after the existence of essence has ended, that is, it is a given memory, recreated in reflection. Such meaning is a trace of existence, or the truth of essence. The trace of being-there turns out to be the act of experience itself, recreated in reflection, as the truth of certainty. Nine traces or evidences of being-there are distinguished: the reality of the real (sensory data), the obviousness of the ideal, the correctness of the conclusion, the reliability of value, the adequacy of knowledge, the authenticity of the artistic image, the dignity of man, the effectiveness of the thing and the justice of society. The denial of these existential predicates represents forms of lies, or the non-bearer (nothing); the denial of the certainty of the truth of being-there represents non-being. Between lies and truth, various forms of neutral ontological-epistemic status are possible: possibility with its types, that is, probabilities of varying degrees. Between being-there and being-there is a difference established, consisting in the fact that the former is secondary in relation to the latter; as well as a similarity, consisting in the fact that both forms of being represent a passive statement of the inevitable, in contrast to a free construction, expressed in value-oriented activity.
