Man does not die unless his body, and the material systems of which his body is composed, dies. Nevertheless, man's body is not just "a body," but "a way of being a body" (20). To a considerable extent, this way of being a body is made up of "possibilities" which may or may not be fulfilled, but which in any case are "real." Now, a moment may come when all of a human's possibilities become closed to him—which is the same as saying that a man may become aware that he had no future before him.
Nos permite, por ejemplo, responder abiertamente a quienes reclaman no sólo una antropología del hombre, sino también una de los sexos humanos, diciendo que la razón les sobra: «ser hombre» quiere decir «ser hombre o ser mujer» (lo que incluye, dicho sea de paso, la llamada «transexualidad» o aspiración, a veces cumplida, a cambiar de sexo).
