Today those who peer into the future want only relief from anxiety. Unable to face the prospect that the cycles of war will continue, they are desper… - John N. Gray

The evil of totalitarianism is not only that it fails to protect specific liberties but that it extinguishes the very possibility of freedom.

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.

While it is much preferable to anarchy, government cannot abolish the evils of the human condition. At any time the state is only one of the forces that shape human behaviour, and its power is never absolute. At present, fundamentalist religion and organized crime, ethnic-national allegiances and market forces all have the ability to elude the control of government, sometimes to overthrow or capture it. States are at the mercy of events as much as any other human institution, and over the longer course of history all of them fail. As Spinoza recognized, there is no reason to think the cycle of order and anarchy will ever end. Secular thinkers find this view of human affairs dispiriting, and most have retreated to some version of the Christian view in which history is a narrative of redemption. The most common of these narratives are theories of progress, in which the growth of knowledge enables humanity to advance and improve its condition. Actually, humanity cannot advance or retreat, for humanity cannot act: there is no collective entity with intentions or purposes, only ephemeral struggling animals each with its own passions and illusions. The growth of scientific knowledge cannot alter this fact. Believers in progress – whether social democrats or neo-conservatives, Marxists, anarchists or technocratic Positivists – think of ethics and politics as being like science, with each step forward enabling further advances in future. Improvement in society is cumulative, they believe, so that the elimination of one evil can be followed by the removal of others in an open-ended process. But human affairs show no sign of being additive in this way: what is gained can always be lost, sometimes –as with the return of torture as an accepted technique in war and government – in the blink of an eye. Human knowledge tends to increase, but humans do not become any more civilized as a result. They remain prone to every kind of barbarism, and while the growth of knowledge allows them to improve their material conditions, it also increases the savagery of their conflicts.
