Empiricism’s disciples have achieved some impressive results in the practical sphere, but then again, for a while in their times, so did the followers of medieval Christianity, Communism, Nazism, and several other worldviews/theories. They even had their own “sciences,” dictating in detail what their scientists should study and what they should conclude from their studies.

Perhaps the most disturbing examples are the Nazis. They claimed to base their ideology on empiricism and Science. In their propaganda films and in all academic and public discourse, they preached a warped form of Darwinian evolution that enjoined and exhorted all nations, German or non-German, to go to war, seize territory, and exterminate or enslave all competitors—if they could. They claimed this was the way of the world, and it must be so. Hitler’s team were gambling confidently that in this struggle, the “Aryans”, with the Germans in the front ranks, would win.

“In eternal warfare, mankind has become great; in eternal peace, mankind would be ruined.”

                                                                                                                          —Adolf Hitler, Mein Kampf

Such a view of human existence, they claimed, was not cruel or cynical. It was simply built on a mature and realistic acceptance of the truths of Science. If people calmly and clearly look at the evidence of History, they can see that war always comes. Mature, realistic adults learn and practice the arts of war, assiduously in times of peace and ruthlessly in times of war. According to the Nazis, this was merely a logical consequence of accepting the survival-of-the-fittest rule that governs life.

Hitler’s ideas about race and about how the model of Darwinian evolution could be applied to humans, were, from the viewpoint of the real science of Genetics, unsupported. But in the Third Reich, this was never acknowledged.

The disturbing thing about physicists like Werner Heisenberg, chemists like Otto Hahn, and biologists like Ernst Lehmann becoming willing tools of Nazism is not so much that they became Hitler’s puppets, but that their life philosophy as scientists did not equip them to break free of the Nazis’ distorted version of Science. Their religions failed them, but clearly, in moral terms, Science failed them too.

There is certainly evidence in human history that the consequences of Science being misunderstood can be horrible. Nazism became humanity’s nightmare. Some of its worst atrocities were committed in the name of advancing science.¹⁴ Under Nazism, medical experiments especially passed all nightmares.

For practical, evidence-based reasons, then, as well as for theoretical ones, millions of people around the world today have become deeply skeptical about all systems of thought and, in moral matters at least, about scientific idea systems in particular. At primal levels, we are driven to wonder: Should we trust something as critical as the survival of our culture, our knowledge, our children and grandchildren, and even our Science itself to a way of thinking that, in the first place, can’t explain itself, and in the second place, has had some large and dismal practical failures in the past?

In the meantime, in this book, we must get on with trying to build a base for a universal moral code. Reality requires that we do so. It will not let us procrastinate. It forces us to think, choose, and act every day. To do these things well, we need a guide, that is, a moral code. Empiricism as base for the moral code project simply does not inspire confidence.

Is there something else to which we might turn?
