“Enough” was a word that referred to quantity without requiring anyone to state the standard by which it was measured. That was why it was dangerous. Enough oxygen. Enough energy. Enough passages. Enough review. A sentence could be complete without specifying who needed how much. Those who said there was enough could end their calculations, while those who said there was not enough could obtain a new budget.
In the early days of galactic settlement, the word “enough” served as a justification for economy. One passage was judged enough for a settlement of one hundred residents. After the first passage was severed and all one hundred were isolated, two became necessary. When both passages were damaged by the same stellar storm, three became the legal standard.
The sentence “Three are enough” was never used again. The moment someone declared that there was enough, that person became responsible for the next accident. Engineers calculated the worst possible accidents. Regulatory authorities demanded that engineers account for accidents they had not imagined. Insurance companies asked what would happen if both accidents occurred simultaneously, and civic organizations demanded preparations for the possibility that the insurance companies themselves might go bankrupt.
Standards continued to rise. At some point, “enough” no longer meant satisfaction. It meant that no further grounds for demanding more had yet been discovered. Governments removed the word from official documents. “Enough energy” became “energy meeting demand within the current range of predictions.” “Enough review” became “a state in which responses to all registered objections have been completed.” Sentences became more precise, and no one could feel reassured.
Precise anxiety became civilization’s largest industry. Citizens demanded more reserve passages, reserve bodies, and reserve cities. These measures genuinely improved safety. The probability that any one settlement would disappear continued to decline. The number of settlements increased even faster. Each settlement survived, and the galaxy as a whole became more vulnerable. The same thing happened in energy production. When one star system lacked sufficient energy, it was connected to another. As the available energy in the connected systems increased, population, computation, and travel increased with it. Each time new supplies arrived, the previous shortage was resolved and a larger shortage emerged.
Civilization never had enough energy. Whenever it felt that it had enough, it invented new ways to use it. When the photon deficit was discovered, the government announced that the remaining energy was enough to meet current demand. The statement was true. If current demand alone had been maintained, civilization could have survived for millions more years. The markets interpreted the announcement as meaning that millions of years of surplus had become available. New passages were constructed, more distant settlements were established, and computational worlds were created in advance for citizens who had not yet been born. The determination that there was enough increased demand until there was no longer enough.
Afterward, “enough” was classified as an expression that induced fear. When a doctor told a patient there was enough oxygen, the patient understood it to mean that oxygen was running out. When a government announced that there was enough food, citizens rushed to storage facilities. When a bank explained that it had enough capacity to meet its obligations, withdrawals began. Civilization could endure shortages, but it could not endure announcements that there was enough. After the Life Continuity Guarantee Decree came into effect, energy consumption per citizen fell substantially. The government announced the figures as an achievement. But the number of protected citizens and people awaiting restoration grew even faster, and total consumption, which had declined for a time, began to rise again. The energy that was enough for one person could not sustain everyone.
The last scientist attempted to calculate how much energy would have to accumulate in the storage space for life to arise in the future. He obtained no answer. If there was too little energy, nothing might happen, but even a large amount did not guarantee that life would emerge. He had not determined the deficit rate, nor had he caused any new energy to leak from the past. He created a boundary where the portion of energy that had already flowed away but could still perform work might arrive. Whether the amount gathered there was enough was never established.
“Enough” was not prohibited because it could no longer be used. It was prohibited because, once used, it could not be stopped.
