We Must Plan for the Future, or Watch Our World Collapse

In her recent book, The Watchman’s Rattle (subtitled “Thinking our way out of extinction”), Rebecca Costa delivers a fascinating account of how civilizations die. Their problems become too complex, she says. Societies reach what she calls a cognitive threshold. They simply can’t chart a path from the present to the future.

The example she gives is the Mayans. For a period of three and a half thousand years, between 2,600 BCE and 900 CE, they developed an extraordinary civilization, spread over what is today Mexico, Guatemala, Honduras, El Salvador and Belize — with an estimated population of 15 million people.

Not only were they master potters, weavers, architects and farmers, but they developed an intricate cylindrical calendar system, with celestial charts to track the movements of the stars and predict weather patterns. They had their own unique form of writing, as well as an advanced mathematical system. Most impressively, they developed a water-supply infrastructure involving a complex network of reservoirs, canals, dams and levees.

Then suddenly, for reasons we still don’t fully understand, the entire system collapsed. Sometime between the middle of the eighth and ninth century, the majority of the Mayan people simply disappeared. There have been many theories as to why it happened. It may have been a prolonged drought, overpopulation, internecine wars, a devastating epidemic, food shortages or a combination of these and other factors. One way or another, having survived for 35 centuries, Mayan civilization failed and became extinct.

Costa’s argument is that whatever the causes, the Mayan collapse, like the fall of the Roman Empire and the Khmer Empire of thirteenth century Cambodia, occurred because problems became too many and complicated for the people of that time and place to solve. There was cognitive overload, and systems broke down.

It can happen to any civilization. And it may, she says, be happening to ours.

The first sign of breakdown is gridlock. Instead of dealing with what everyone can see are major problems, people continue as usual and simply pass their problems on to the next generation. The second sign is a retreat into irrationality. Since people can no longer cope with the facts, they take refuge in religious consolations. The Mayans took to offering sacrifices.

Archeologists have uncovered gruesome evidence of human sacrifice on a vast scale. It seems that, unable to solve their problems rationally, the Mayans focused on placating the gods by manically making offerings to them. So, apparently, did the Khmer.

This makes the case of Jews and Judaism fascinating. We faced two centuries of crisis under Roman rule between Pompey’s conquest in 63 BCE and the collapse of the Bar Kochba rebellion in 135 CE. We were hopelessly factionalized. Long before the Great Rebellion against Rome and the destruction of the Second Temple, Jews were expecting a major cataclysm.

What is remarkable is that we did not focus obsessively on sacrifices, like the Mayans and the Khmer. Instead, we focused on finding substitutes for sacrifice. One was gemillat chassadim, acts of kindness. Rabban Yochanan ben Zakkai comforted Rabbi Joshua, who wondered how Israel would atone for its sins without sacrifices, with these words: “My son we have another atonement as effective as this: acts of kindness, as it is written, ‘I desire kindness and not sacrifice.’”

Another was Torah study. The sages interpreted Malachi’s words (1:11), “In every place offerings are presented to My name,” to refer to scholars who study the laws of sacrifice.

Another was prayer. Hosea said, “Take words with you and return to the Lord. … We will offer our lips as sacrifices of bulls,” implying that words could take the place of sacrifice. “He who prays in the house of prayer is as if he brought a pure oblation.”

Yet another was teshuvah. The Psalm (51:19) says “the sacrifices of God are a contrite spirit.” From this, the sages inferred that “if a person repents it is accounted to him as if he had gone up to Jerusalem and built the Temple and the altar and offered on it all the sacrifices ordained in the Torah.”

A fifth was fasting. Since going without food diminished a person’s fat and blood, it counted as a substitute for the fat and blood of a sacrifice. A sixth was hospitality. “As long as the Temple stood, the altar atoned for Israel, but now a person’s table atones for him”

What is striking in hindsight is how, rather than clinging obsessively to the past, sages like Rabban Yochanan ben Zakkai thought forward to a worst-case-scenario future. The great question raised by this week’s parsha, Tzav, which is all about different kinds of sacrifice, is not “Why were sacrifices commanded in the first place?” Rather, it asks, how did Judaism survive without them?

The short answer is that the prophets, sages and Jewish thinkers of the Middle Ages realized that sacrifices were symbolic enactments of processes of mind, heart and deed that could be expressed in other ways as well. We can encounter the will of God by Torah study, engage in the service of God by prayer, make financial sacrifice by charity, create sacred fellowship by hospitality and so on.

Jews did not abandon the past. We still refer constantly to sacrifices in our prayers. But we did not cling to the past. Nor did we take refuge in irrationality. We thought through the future and created institutions like the that could be built anywhere and sustain Jewish identity even in the most adverse conditions.

That is no small achievement. The world’s greatest civilizations have all, in time, become extinct, while Judaism has always survived. In one sense, that was surely Divine Providence. But in another, it was the foresight of people like Rabban Yochanan ben Zakkai, who resisted cognitive breakdown, created solutions today for the problems of tomorrow. He did not seek refuge in the irrational, but quietly built the Jewish future.

Surely there is a lesson here for the Jewish people today — plan generations ahead. Think at least 25 years into the future. Contemplate worst-case scenarios. What saved the Jewish people was our ability, despite our deep and abiding faith, never to let go of rational thought — and, despite our loyalty to the past, to keep planning for the future.
