[M]y entire life is less valuable than the entire state of my being dead (which may be identified with the continued existence of the matter and energy that composed my body at the time of my death, even if this matter and energy no longer constitutes a corpse and breaks down into separated and distant atoms). My life can add up only to a finite number of units of value. But my state of being dead lasts for an infinite amount of future time. Even if my state of being dead at each time has the minimal value, say one (the value of the members of the set of particles that composed my body at the time of my death), my state of being dead will have aleph-zero units of value. My state of being dead is infinitely more valuable than my state of being alive. The same is true for any human and any living being.
Most of the time, we live in an illusion of meaningfulness and only some times, when we are philosophically reflective, are we aware of reality and the meaninglessness of our lives. It seems obvious that this has a genetic basis, due to Darwinian laws of evolution. In order to survive and reproduce, it must seem to us most of the time that our actions are not futile, that people have rights. The rare occasions in which we know the truth about life are genetically prevented from overriding living our daily lives with the illusion that they are meaningful. As I progress through this paper, I have the illusion that my efforts are not utterly futile, but right now, as I stop and reflect, I realise that any further effort put into this paper is a futile expenditure of my energy.
