Finitude arises from choice excluding alternatives, not from mortality.

Evidence

Finitude. To be carefully distinguished from “mortality.” Finitude refers not to the fact that man dies but to the fact that as a free choice of his own project of being, he makes himself finite by excluding other possibilities each time that he chooses the one which he prefers. Man would thus because of his facticity be finite even if immortal. — Jean-Paul Sartre, Being and Nothingness, 1485

Categorization

• DEFINE: Sharp definitional distinction: finitude is an ontological product of free project-choice, entirely separable from death.
• DEEPTHINKING: The claim that an immortal being would still be finite inverts common sense entirely — finitude here is not about death but about the structure of choosing one project over others.
• XREF: connects to: Finitude is the condition of freedom, since freedom requires choice. — Jean-Paul Sartre, Being and Nothingness: An Essay on…, 871; Freedom chooses its being but cannot choose not to be — Jean-Paul Sartre, Being and Nothingness: An Essay on…, 1146; Risk emerges only from one’s own decision and action, never from inaction
