Being-in-itself is radically contingent and cannot be derived from anything.

Evidence

Being-in-itself is never either possible or impossible. It is. This is what consciousness expresses in anthropomorphic terms by saying that being is de trop—that is, that consciousness absolutely can not derive being from anything, either from another being, or from a possibility, or from a necessary law. Uncreated, without reason for being, without any connection with another being, being-in-itself is de trop for eternity. — Jean-Paul Sartre, Being and Nothingness, 28

Categorization

• DEFINE: Defines the core ontological term ‘being-in-itself’ and its de trop contingency.
• XREF: Holds the explicit ‘throwness’/Geworfenheit resonance with Heidegger and sets up Beauvoir’s ethics of freedom built on this contingency. — connects to: Being-in-itself is radically contingent, deriving from nothing and reducible to no necessity. — Jean-Paul Sartre, Being and Nothingness: An Essay on…, 166; Being-in-itself can found its nothingness but never its being — Jean-Paul Sartre, Being and Nothingness: An Essay on…, 346
• ADDENDUM: The uncreated, unjustifiable contingency of being parallels the sacrificial logic explored in the sacrifice piece — being there for no reason, like the immolated.
