If the man had no awareness of death, it would be only perishable, dying the spirit has transformed the physical act of perishing of the organism in an act of conscience. Know what to die is equal to know that must live and therefore transcend living and dying. The man with his thought, embraces not only the universe (Pascal), but embraces life and death, knowing that one has to live and who must die is already a knowledge that is immortal. I can’t give an immortality but is natural principle of man; immortality is metaphysically necessary; If the man is perishable, it would not have awareness of dying, this goes against Unamuno. If the spirit transcends throughout his act, it also transcends that Act which is also the death of that body in which are essentially interested. All spirit is uniquely created by God, God is the Act essendi (of being) of all existing spiritual; the body is made for the spirit, whose sole purpose is not temporary life. The spiritual principle as such is immaterial.
The spirit is not identified with the reason, is will. Death is zero in the freedom of time, to the birth we have before us the entire field of possibilities, in this case we recover the maximum of freedom. Death destroys freedom as number series (the possibilities), but gives one freedom, the one absolute freedom to the eternal. It is freedom in time which prepares another freedom, aging weaken our vital needs, possibilities and concrete actions and we lose the freedom of time, but this loss sets us free from the conditioning of temporary life. With old age, is acquired certain disinterest and indifference with regard to things, balance, which allows to look with detachment the men and things. Perception of the sensible and with it the possibility of time ceases with death. Death is not the opposite of life, the natural repugnance of death is not own the spirit, but the body, the vital instinct is so strong that it obliges the spirit to forget death which however is not afraid.
