If the larger picture of ancient forager life is hard to reconstruct, particular events are largely irretrievable. When a Sapiens band first entered a valley inhabited by Neanderthals, the following years might have witnessed a breathtaking historical drama. Unfortunately, nothing would have survived from such an encounter except, at best, a few fossilised bones and a handful of stone tools that remain mute under the most intense scholarly inquisitions. We may extract from them information about human anatomy, human technology, human diet, and perhaps even human social structure. But they reveal nothing about the political alliance forged between neighbouring Sapiens bands, about the spirits of the dead that blessed this alliance, or about the ivory beads secretly given to the local witch doctor in order to secure the blessing of the spirits. This curtain of silence shrouds tens of thousands of years of history. These long millennia may well have witnessed wars and revolutions, ecstatic religious movements, profound philosophical theories, incomparable artistic masterpieces. The foragers may have had their all-conquering Napoleons, who ruled empires half the size of Luxembourg; gifted Beethovens who lacked symphony orchestras but brought people to tears with the sound of their bamboo flutes; and charismatic prophets who revealed the words of a local oak tree rather than those of a universal creator god. But these are all mere guesses. The curtain of silence is so thick that we cannot even be sure such things occurred – let alone describe them in detail.

The weather, for example, is a level one chaotic system. Though it is influenced by myriad factors, we can build computer models that take more and more of them into consideration, and produce better and better weather forecasts. Level two chaos is chaos that reacts to predictions about it, and therefore can never be predicted accurately. Markets, for example, are a level two chaotic system.

“Raise Prices” This was Marc’s response to “If you could have a billboard anywhere, what would it say?” He’d put it right in the heart of San Francisco, and here’s the reason: “The number-one theme that companies have when they really struggle is they are not charging enough for their product. It has become conventional wisdom in Silicon Valley that the way to succeed is to price your product as low as possible, under the theory that if it’s low-priced, everybody can buy it, and that’s how you get to volume,” he said. “And we just see over and over and over again people failing with that, because they get into a problem called ‘too hungry to eat.’ They don’t charge enough for their product to be able to afford the sales and marketing required to actually get anybody to buy it. Is your product any good if people won’t pay more for it?”
