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.
