Teleology has suffered mightily at the hands of science. Darwinian evolution is a core dogma of modern science. It is a dogma that severely undermines teleology. To ask about the purpose of life is to ask a meaningless question. Life evolved over a very long period as the unplanned result of random events.
Life is an accident.
Those who seek a pattern, a purpose, or a meaning, are involved in a futile and misguided effort. Those who claim to see a pattern see an illusion. They might as well claim to see the shapes of bears and hunters in the stars of the night sky. The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil and no good, nothing but blind, pitiless indifference. I suspect that Wright has some misgivings about this world view, as well.
