From a Darwinian point of view, human beliefs are adaptations to our part of the world. No doubt much of what we believe must be roughly accurate, or else we would not have survived. But the beliefs we have evolved might latch on to the world only enough to help us stumble our way through it, and then only for the time being. Human belief-systems could be useful illusions, appearing and disappearing as they prove to be more or less advantageous in the random walk of natural selection. Might not evolution be one of these illusions? Scientific naturalism is the theory that human beliefs are evolutionary adaptations whose survival has nothing to do with their truth. But in that case scientific naturalism is self-defeating, since on its own premises scientific theories cannot be known to be true.

How we come to have the world-views we do is an interesting question. No doubt reason plays a part, but human needs for meaning and purpose are usually more important. At times personal taste may be what decides the issue. There is nothing to say that, when all the work of reason is done, only one view of the world will remain. There may be many that fit everything that can be known. In that case you might as well choose the view of the world you find most interesting or beautiful. Adopting a world-view is more like selecting a painting to furnish a room than testing a scientific theory. The test is how it fits with your life.

The repression of liberty that took place in the countries in which Communist regimes were established cannot be adequately explained as a product of backwardness, or of errors in the application of Marxian theory. It was the result of a resolute attempt to realize an Enlightenment utopia - a condition of society in which no serious form of conflict any longer exists.
