When you visit an ancient archaeological site, it is seductive to speculate what these people might have felt and how they might have understood the world. We can examine how their buildings were constructed, how they decorated their homes by excavating the art, and what they ate ascertained from the bone deposits. But of their minds, there are only tantalizing inferences from these material remains. Lewis Willliams and Pearce advance a controversial archaeological thesis: namely, that there are elements of ecstatic religious experience “hard-wired” into the human brain and, hence, that these are universal.
They propose a three-stage model of such experiences. In step 1, the shaman enters a trance state (induced by drugs or activities such as dancing) leading to visual disturbances, typically including gratings, cobwebs and spirals. In step 2, the shaman attempts to interpret these as culturally relevant, typically including the interpretation of spirals and vortices as tunnels leading to another realm. Step 3 involves full-blown hallucinations in which memories are activated and which involve human-animal hybrids. On the basis of these experiences, a cosmology arises, also involving three tiers (which, notably, are not derived by causal analysis from the claimed sensory stages but rather are asserted): the realm of the dead ancestors, the realm of everyday life, and the realm of the spirits. These three tiers are memorialized, they claim, in the structures of monuments and the design of houses
From this, they want to argue that the Neolithic Revolution some 10,000 years ago, in which plants and animals were first domesticated, was driven by the need to provision large numbers taking part in religious rituals at sites like Gobleke Tepe in Turkey or Stonehenge in the UK. They contrast this with conventional explanations in which the abandonment of hunter-gathering and the turn to agriculture was driven by material forces such as climate change or population growth.
Chapter 1 reveals their method. The elements of their theses appear as quick assertions in a summary of the archaeological summary. Here is an example: “The good quality of Karacadag grain may [emphasis added] have led some workers returning home to take some with them to sow in their own gardens.” Since these asides are brief, the reader shows forbearance, taking them to be a summary of what will be demonstrated with evidence later. But, of course, through a “persistence of vision” conjuring trick. when the demonstration comes, the reader is already primed to accept them.
Let’s take a closer look at a chapter to dissect how this illusion is achieved. Chapter 2 deals with the claim of a universal brain wiring that creates common altered states of consciousness. Altered states of consciousness are described (and the three stage model introduced) but no neurobiological evidence is introduced to support the claim. The whole edifice rests on a foundation of eight testimonies of altered mental states. This framework is then used to interpret a range of highly selected archaeological and ethnological data as confirmation. The book segues from the Near Eastern to the West European Neolithic, without troubling to pass through the Eastern and Central European archaeological record.
The model failed to convince me. Nevertheless, more despite than because of their model, there are interesting possible insights into Neolithic cultures. I found the three-tiered cosmology fitted plausibly with the architecture of the nine thousand year old settlement of Çatalhöyük in Turkey. Here people lived in dimly lit houses, buried their dead in an underworld below the floor, and emerged up ladders to the roof entrance and the skyworld. I also found their argument that some adepts can ”merge” with animal spirits consistent with evidence from that civilisation’s art.
