What's important is that all human knowledge be made available to all intelligent people who want to learn it.

Evolution is one of the two or three most primally fascinating subjects in all the sciences.

How did scientists get money in the past? They were either lucky and independently wealthy, like Darwin, or they had patrons, like Galileo. Universities or governments have become patrons only in the last few generations. Many of the great scientists of the past were in debt to their patrons in the same sense that modern scientists are influenced by what their granting agencies want.

But we all recognise the primary foible of frail humanity - our propensity for embracing hope and shunning logic, our tendency to believe what we desire rather than what we observe.

Results rarely specify their causes unambiguously. If we have no direct evidence of fossils or human chronicles, if we are forced to infer a process only from its modern results, then we are usually stymied or reduced to speculation about probabilities. For many roads lead to almost any Rome.

The argument that the literal story of Genesis can qualify as science collapses on three major grounds: the creationists' need to invoke miracles in order to compress the events of the earth's history into the biblical span of a few thousand years; their unwillingness to abandon claims clearly disproved, including the assertion that all fossils are products of Noah's flood; and their reliance upon distortion, misquote, half-quote, and citation out of context to characterize the ideas of their opponents.

Human consciousness arose but a minute before midnight on the geological clock. Yet we mayflies try to bend an ancient world to our purposes, ignorant perhaps of the messages buried in its long history. Let us hope that we are still in the early morning of our April day.
