The concept of the existential self-function (ESF) also provides a clarification of the ever felt - (but not [a clarification] of the vulgar, and directly resulting in the absurd, [part], and also not [a clarification] of the spiritually illusionary) - part of ideas about death and life-after-death. : The mere psychological substrate of the personal, and its fundamental molecular ESF-ional consciousness function, spontaneously disintegrates together with the substate matter and is dissipated at the same moment in a truly uncomparable irreversible degree.
Demise of ESF means (for the organism in question, the person in question) the transition toward the state of not-existing-anymore, toward a dynamically especially demonstrative form of non-existence. Logically, not any of our existential concepts (that is, also those of life-after-death, meet again, reunion) can be applied to this state of non-existence, meaning that neither the corporeal individual nor its function of consciousness, i.e. the so-called spiritual individuum, has, in the framework of our categories of thinking and of all our experiences, not the least perspective to exist beyond the limits of death.
Nevertheless, there is a small "opening" : For to our thinking categories as consciousness-functional aids of existence of right-out amazing power, are added certain premonitions and feelings of discomfort, longings, wishes, and after-death images, which one, without deadly contradiction, may take as undeveloped thinking categories. They then would be, so to say, "antennae" over and above the normal limits of consciousness. To conclude from this -- also for us personally (!) still advantageous -- to life-after-death is an opinion which readily presents itself as attractive, which cannot, however, be exhausted in detailed defining, that is, an opinion which must lose itself in unlimited phantasies. Remaining on empirical grounds we can merely say :
When mankind has perished, also the sun has perished. And all human depictions of the world have gone down, because they were living only in us. But then also all wishes, expectations, and hopes, have irrevocably vanished, and thus also the wish to live beyond [physical] death, a wish that only occurs in the living (and thus there where it is substantially, but not psychologically, "in fact" without any value). To the living it is [psychologically] useful, for the dead it has become irrelevant, they do not need it anymore. Their extended life is of some other nature [in the form of the continued existence of their elements].
