Chapter 11.                     Part K 

Discussing and interpreting the moral implications of the new worldview offered by the New Physics will be the business of my next two chapters. I will present a moral code and an argument for it that is not as all-encompassing as Hegel’s, but is more useful. The theory of morality presented in the remainder of this book offers some firmer measures by which to judge our actions.  


                                                      
                
                                                                    Karl Popper 

On the other hand, it will not satisfy the demands of the most exacting philosophers, such as, for example, Karl Popper and his disciples. (4.) Popper loved the physical sciences and considered them to be models of what Science should be, but he found Biology disappointing because he felt its foundational theories (notably the Theory of Evolution) could not be tested in neat, clear ways to see whether they could be falsified. He then wrote the social sciences off pretty much completely.

Popper argued that only theories which can be tested in ways that risk their being falsified deserve to be called “Science”. He was deeply impressed by the Theory of Relativity, for example, because it was formulated in such a way that it could be tested definitively. If it had failed to predict Eddington's observations of the stars visible during a full solar eclipse, then the theory would have to be viewed as a failure. But it succeeded brilliantly, and Einstein's international reputation soared. 
      
Biology is not that neat. The Theory of Evolution can only be tested in ways that, if successful, may make it seem more likely to be true. In his early work, Popper did not even want to call Biology a “science”. But gradually, over years, he came to concede that some theories could make probabilistic, Bayesian kinds of predictions, rather than neat, causally linked ones, and still be rigorous enough to be properly called "scientific". The psychological theories of Adler and the historical ones of Marx weren’t that kind of useful, but Popper came to see that the Theory of Evolution was. (5.)

We accept now that the history of life does not proceed by cause-effect steps as they are pictured under the Enlightenment worldview. Instead life proceeds forward through time like a river with many branches and tributaries connecting to the main channel. The difference is that life flows "uphill". It flows against the gradient of entropy, opportunistically searching for new habitats in which some new species or new way of life may take root, adapt, and flourish. This is a better, more helpful metaphor for describing how life moves across time.

Under this model, the life flow keep bifurcating. Some forks get detoured and some get blocked completely and die out. Whether a given branch will be present further on in the natural history of the world is dependent on many odds-governed factors such as changing climates, the rates of evolution of other species (especially those that are its food, its competion, and its predators), and so on. But the whole system keeps expanding relentlessly as is shown by the way the amount of biomass on this planet has been increasing since life began here about three billion years ago.

The model of human cultural evolution presented in the rest of this book will not satisfy Popper's most rigorous early demands, but it will do what we need it to do. It will give us categories that will lead us, via logic and evidence, to guidelines that we can use to steer our path, as a species, toward better odds of surviving over the long haul.
