The key question
Whether we realize it or not, all of us possess a worldview. A few years after birth, we all gradually formulate our philosophy of life. Most of us make one of two basic assumptions: we view the universe as a result of random events and life on this planet a matter of chance; or we assume an Intelligence beyond the universe who gives the universe order, and life meaning. Our worldview informs our personal, social, and political lives... tells more about us perhaps than any other aspect of our personal history.
The origin of species?
For I am well aware that scarcely a single point is discussed in this volume on which facts cannot be adduced, often apparently leading to conclusions directly opposite to those at which I have arrived. A fair result can be obtained only by fully stating and balancing the facts and arguments on both sides of each question; and this cannot possibly be here done. ... I must premise, that I have nothing to do with the origin of the primary mental powers, any more than I have with that of life itself.
The origin of life
The world has arisen in some way or another. How it originated is the great question, and Darwin's theory, like all other attempts to explain the origin of life, is thus far merely conjectural. I believe he has not even made the best conjecture possible in the present state of our knowledge. The more I look at the great complex of the animal world, the more sure do I feel that we have not yet reached its hidden meaning, and the more do I regret that the young and ardent spirits of our day give themselves to speculation rather than to close and accurate investigation.
The origin of specified information
The key test is this: show me a process that generates information, and large amounts of specified information, without the guidance of an intelligent agent. ... everything we know is that only intelligence produces information. So test our theories against our knowledge of the cause and effect structure of the world.
