The wheel has been around since about 4000 BCE (Bulliet, 2016). The first wheels used for transportation may have derived from potters’ wheels used for moulding cups and bowls. Some early wheels were made of stone, but these were soon replaced by wood which was lighter and faster. Around 3000 BCE spokes were invented, and for several thousand years fast-moving chariots with spoked wheels often decided ancient battles.
By the middle of the nineteenth century wooden wheels for carts and carriages had become fully developed (see figure). The rim was made by bending ash to form curved felloes. These were attached to the hub by strong oak spokes, and held in place by a steel tire.
In the last two hundred years the wheel has changed dramatically. Some changes have made the wheels more efficient (working well) and some made them more attractive (looking lovely). The forces driving the changes are thus similar to those that occur during evolution with its survival of the fittest and its sexual selection. However, wheel innovation is controlled by human design rather than random mutation, and the changes have occurred much more rapidly. And, as in evolution, some innovations do not survive: hubcaps and whitewall tires have become extinct.
Loss of Paradise
The ancients did not believe in progress (Bury, 1932; Pollard, 1968; Meek Lange, 2011). They had two main ideas of how the world changes over time. One was that an initial state of peace and plenty – the Garden of Eden of Genesis, the Golden Age of Hesiod, or the Arcadia of Virgil – had degenerated over time to our present world of strife and suffering.
The decline from our golden beginnings to the present age of iron might have been simply caused by the passage of time, but more often than not it was attributed to human foolishness. The Jews told the story of original sin and the Greeks recounted the myth of Pandora’s box.

Imagine yourself 20 years from now. A brilliant cognitive neuroscientist claims to be able to read your brain and predict your future behavior. She studied with Sam Harris in Los Angeles and then completed her postdoctoral work with Chun Siong Soon and John-Dylan Haynes in Berlin. She knows her stuff and she uses the most advanced technology.
You will be able to press one of five buttons. Before you do so, the neuroscientist will take a scan of your brain, analyse it and predict which button you will choose. She will pay particular attention to the posterior cingulate gyrus and the rostral prefrontal cortex. She is willing to bet you that her prediction will be correct.
If you take the bet, you believe in free will. If you do not, you are a determinist – or in this context a “neuro-determinist.”
Faites vos jeux!
