The Argument from Miracles

The argument

The argument from miracles holds that certain extraordinary events — events that apparently violate the laws of nature — constitute evidence of divine intervention and therefore of God’s existence. Christianity places particular weight on the resurrection of Jesus, which the apostle Paul called the foundation of the entire faith: “If Christ has not been raised, your faith is futile” (1 Corinthians 15:17). Islam points to the Quran itself as a literary miracle. Catholicism maintains an elaborate bureaucratic process for certifying miracles, including those required for canonization of saints.

The argument’s appeal is straightforward. If a genuinely supernatural event has occurred — a dead man returning to life, a terminal illness vanishing without explanation, a statue weeping real tears — then naturalism is false, and the door to theism is open. The argument does not require that all reported miracles be genuine; it requires only one. And given the thousands of reported miracles across human history, the argument goes, the probability that every single one is mistaken or fraudulent is vanishingly small.

Hume’s argument against miracles

The most famous philosophical response to miracle claims came from David Hume in Section X of his Enquiry Concerning Human Understanding(1748). Hume’s argument is often misunderstood as a dogmatic denial that miracles can occur. It is not. His argument is about evidence and testimony.

Hume observed that a miracle, by definition, is a violation of the laws of nature. The laws of nature are established by the most extensive and uniform body of evidence we possess: every observation ever made. When someone reports a miracle, they are asking us to accept, on the basis of testimony, that the entire weight of observational evidence has been overturned. Hume’s principle is that we should always proportion our belief to the evidence. The evidence for the laws of nature is as strong as evidence gets. The evidence for the testimony — the reliability of the witness, the possibility of error or fraud — is always weaker. Therefore, it is always more rational to conclude that the testimony is mistaken than that the miracle occurred.

This is not circular. Hume is not assuming miracles cannot happen. He is arguing that the evidence required to establish that one has happened must be extraordinarily strong — stronger, in fact, than the evidence we typically have. As Carl Sagan later put it: “Extraordinary claims require extraordinary evidence.”

The problem of competing miracle claims

Every major religion claims miracles. Christians cite the resurrection. Muslims cite the inimitability of the Quran. Hindus cite the miracles of Sathya Sai Baba. Catholics certify apparitions at Lourdes and Fatima. Mormons testify to Joseph Smith’s revelatory experiences. Each tradition treats its own miracles as genuine evidence and the miracles of other traditions as delusion, fraud, or demonic deception.

This presents a logical problem. If miracles are reliable evidence for the religion in which they occur, they simultaneously confirm Christianity, Islam, Hinduism, Mormonism, and dozens of other mutually exclusive faiths. They cannot all be right. The believer who accepts Christian miracles while dismissing Hindu miracles is applying a double standard: the same evidential criteria that validate the resurrection would validate the milk miracle of 1995, when Hindu statues around the world were reported to drink milk offered by devotees.

The honest conclusion is that miracle claims, far from supporting any one religion, actually undermine the reliability of miracle testimony in general. They demonstrate that human beings across all cultures are prone to reporting, believing, and propagating miracle stories — regardless of whether the underlying events actually occurred.

Why personal testimony isn’t enough

Much of the evidence for miracles comes in the form of personal testimony: someone reports a healing, a vision, an inexplicable event. Testimony is valuable evidence in many contexts — courts, journalism, everyday life. But its reliability varies enormously depending on the claim being made. If a colleague tells you she had pasta for lunch, you accept it without question. If she tells you she levitated during lunch, you require more.

The psychology of testimony is well understood. Humans are subject to confirmation bias, motivated reasoning, groupthink, and pattern recognition in random events. We misremember details, embellish stories in retelling, and unconsciously align our memories with our expectations. Eyewitness testimony is so unreliable that it is the single leading cause of wrongful convictions in the criminal justice system — and those are cases involving ordinary, everyday events, not violations of physical law.

Medical “miracle” healings face an additional problem: spontaneous remission. Cancers occasionally vanish without treatment. Conditions are misdiagnosed. Symptoms fluctuate. The human body surprises even experienced physicians. When a healing occurs after prayer, the prayer gets the credit; when it occurs without prayer, it is simply filed as an unexplained remission. This is textbook confirmation bias: counting the hits and ignoring the misses.

The decline of miracles in the age of cameras

There is a striking pattern in the history of miracle claims: they become rarer and less dramatic as our ability to verify them increases. In the ancient world, miracles were commonplace — the dead rose, seas parted, the sun stopped in the sky. In the medieval period, saints levitated and performed impossible healings. In the modern era, miracles have retreated to the margins: weeping statues, faces in toast, vague feelings of presence.

James Randi offered one million dollars to anyone who could demonstrate a supernatural or paranormal event under controlled scientific conditions. The prize stood for decades. No one ever claimed it. Faith healers who filled stadiums declined to be tested. Psychics who performed confidently on television refused laboratory conditions. The pattern is consistent: miracle claims flourish where verification is absent and evaporate where it is present.

Today, billions of people carry high-definition cameras in their pockets. Satellites photograph every square meter of Earth’s surface. Medical records are digitized and auditable. And yet the age of ubiquitous surveillance has produced not a single verified miracle — not one instance of a limb regrowing, a confirmed resurrection, or a physical law being unambiguously violated on camera. The simplest explanation is that miracles do not occur. The more complex explanation — that they occur but only when no one is recording — should strike any honest person as suspiciously convenient.

The argument from miracles asks us to believe that the laws of nature have been suspended on the basis of ancient, uncorroborated testimony from pre-scientific cultures. It asks us to accept one tradition’s miracle claims while dismissing identical claims from rival traditions. And it asks us to ignore the systematic failure of miracle claims to survive scrutiny. That is not a reasonable basis for belief. It is a testament to the human capacity for wishful thinking.
