“Our self-awareness impresses itself on us so cogently, as individuals and as a species, that we cannot imagine ourselves out of existence, even though for hundreds of millions of years humans played no part in the flow of life on the planet. When Teilhard de Chardin wrote, "The phenomenon of Man was essentially foreordained from the beginning," he was speaking from the depth of individual experience, which we all share, as much as from religious philosophy. Our inability to imagine a world without Homo sapiens has a profound impact on our view of ourselves; it becomes seductively easy to imagine that our evolution was inevitable. And inevitability gives meaning to life, because there is a deep security in believing that the way things are is the way they were meant to be.”
