Perceived personal permanence is borrowed from stable surroundings, not from the for-itself

Evidence

The For-itself is a temporalization. This means that it is not but that it “makes itself.” It is the situation which must account for that substantial permanence which we readily recognize in people (“He has not changed.” “He is always the same.”) and which the person experiences empirically in most cases as being his own. The free perseverance in a single project does not imply any permanence; quite the contrary, it is a perpetual renewal of my engagement—as we have seen. On the other hand, the realities enveloped and illuminated by a project which develops and confirms itself present the permanence of the in-itself; and to the extent that they refer our image to us, they support us with their everlastingness; in fact it frequently happens that we take their permanence for our own. — Jean-Paul Sartre, Being and Nothingness, 1283

Categorization

• DEFINE: Clarifies how the for-itself’s continual self-making differs from the apparent stability of persons, which is actually lent by in-itself permanence.
• XREF: The perceived stability of persons sourced from things and others’ judgments maps onto Beauvoir’s account of how women come to be defined as the Other by stable exterior roles. — connects to: Personal possessions and surroundings concretely express one’s fundamental self-choice.; The permanence of change itself grants passing objects an illusion of duration — Georg Simmel, on individuality and social forms_…, 742; Psychic well-being fundamentally depends on the existence of public space — Mark Fisher (edited by Darren Ambrose), K-Punk: The Collected and Unpublished…, 1503 (+1 more)
