Confronting and accepting one's mortality is the precondition for freedom, because the fear of death is the lever by which one becomes a slave to power, convention, or self-deception. To learn how to die is therefore to unlearn how to be dominated.
While humans may be alone in intellectually understanding that they will die, the emotional response to loss — mourning, distress at a companion's death — appears across many animal species. Grieving behavior is thus decoupled from conceptual awareness of mortality.
A person's continued existence after death consists entirely in being remembered by the living. Immortality is not metaphysical but social — sustained only as long as others cherish the memory.
Viewing the corpse not as a sacred remnant but as material undergoing observable decay reframes death as a physical process open to scientific examination. This lens converts the taboo of the dead body into a source of usable knowledge.
