Permanence is a fiction invented by homo sapiens and also an illusion believed by them. The idea is incompatible with the laws of biology and no organism is in possession of it.
The fiction or invented reality of permanence is paired with the notion of the self to give individual homo sapiens the illusion of continuity of and preservation of themselves through time (i.e., a soul). The soul is one fiction that convinces sapiens that they are apart from and superior to the other organisms on the planet.
The invented reality of permanence is also necessary to accept the idea of the progress and advancement of societies toward an ideal state and to accept the notion of continuous economic growth—ideas which often serve as justifications for actions and behaviors which destroy ecosystems and habitats.
