The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis. Everywhere we look, it appears that the world was designed so that we could flourish. The position of the Earth around the sun, the presence of organic materials and water and a warm climate — all make life on our planet possible.
It is all an illusion because, after all, it had to happen somewhere and, in any case, Darwin and the evolutionists have proved that life can spontaneously arise:
Yet, with perhaps 100 billion solar systems in our galaxy alone, with ubiquitous water, carbon and hydrogen, it isn't surprising that these conditions would arise somewhere. And as to the diversity of life on Earth — as Darwin described more than 150 years ago and experiments ever since have validated — natural selection in evolving life forms can establish both diversity and order without any governing plan.
So don’t be fooled by the world’s apparent design. It is all an illusion coming from your inner psychological needs which, Krauss, because he’s a cosmologist, is painfully aware of:
As a cosmologist, a scientist who studies the origin and evolution of the universe, I am painfully aware that our illusions nonetheless reflect a deep human need to assume that the existence of the Earth, of life and of the universe and the laws that govern it require something more profound. For many, to live in a universe that may have no purpose, and no creator, is unthinkable.
Krauss, of course, has no such biases as evidence by his brand new conclusion that man is the measure of all things:
Does all of this prove that our universe and the laws that govern it arose spontaneously without divine guidance or purpose? No, but it means it is possible. And that possibility need not imply that our own lives are devoid of meaning. Instead of divine purpose, the meaning in our lives can arise from what we make of ourselves, from our relationships and our institutions, from the achievements of the human mind.
That’s just good solid scientific research.
