Today we look at one of the most important court cases in the history of American education — a case that is central for anyone seriously interested in how we draw the line between science and religion. It is usually called by the name of one of the plaintiffs: Kitzmiller v. Dover Area School District. Dover is a small municipality in Pennsylvania. But the case quickly became a matter of national importance, debated on major television networks and in the press.
How It Started
In October 2004, the Dover Area School Board voted six to three to require that a statement about Intelligent Design be read to ninth-grade biology students alongside the teaching of evolution. The statement told students that evolution is “a theory, not a fact,” and that Intelligent Design offered an alternative explanation for the origins of life.
A brief epistemological note is necessary here. Setting “theory” against “fact” in this way is a category error. When proponents of Intelligent Design say evolution is “just a theory,” they reveal a fundamental misunderstanding of how science works. A scientific theory is not a guess or a hunch. It is an organised body of empirical data explained in the most logical and coherent way available. Proposing as an alternative to scientific theory something without empirical support is not an act of intellectual humility — it is a substitution of terms.
The school also arranged for students to have access to a book called Of Pandas and People, donated by an “anonymous” source later identified as a member of the school board.
What Is Intelligent Design
In the early 2000s, Intelligent Design was fashionable in the United States. Even President George W. Bush mentioned it approvingly.
The core of the idea is a claim about complexity: living organisms are so intricate, so finely tuned, that they cannot have arisen through natural processes. Therefore — so the argument goes — they must have been designed by some Intelligent Creator. This is explicitly a supernatural explanation, and it places Intelligent Design in direct conflict with the naturalistic framework that underlies modern science.
The Lawsuit
After the disclaimer policy was introduced, a group of parents objected. Tammy Kitzmiller and ten other families filed suit, supported by the American Civil Liberties Union (ACLU). The case reached the United States District Court for the Middle District of Pennsylvania.
The central legal problem: taxpayer money was being used in public schools to present a religious worldview rather than a scientific one. This violates the Establishment Clause of the First Amendment to the Constitution, which prohibits the government from promoting religion. The legal precedent was clear — in Edwards v. Aguillard (1987), the Supreme Court had already struck down the mandatory teaching of creationism in Louisiana public schools.
The Judge
The case was assigned to Judge John E. Jones III — a conservative Republican, a practicing Lutheran, appointed to the bench by President Bush. On the surface, this seemed likely to favour the defense. But American courts require judges to set aside personal belief and rule on law and evidence alone.
The Arguments
The plaintiffs argued that Intelligent Design is not science and therefore cannot be taught in public schools. Their strongest piece of evidence was the history of Of Pandas and People itself. Philosopher of science Barbara Forrest showed the court earlier drafts of the book. The word “creationism” appeared hundreds of times in those drafts. Immediately after the Supreme Court banned creationism from public schools in 1987, the authors had simply replaced “creationism” with “intelligent design” — a mechanical text substitution with no change in content. The relabeling was caught in the manuscript record.
The defense tried to establish that Intelligent Design was a legitimate scientific theory. The familiar argument returned: evolution is “just a theory,” there are “gaps in Darwin’s theory,” there is legitimate scientific controversy here.
But this logic, if accepted, would have no stopping point. Why not also teach flat earth theory? Or alternative historical chronologies? If the criterion for inclusion is “someone disputes the mainstream view,” the doors open to anything. The road the defense was travelling leads to a position where all claims are treated as equally valid — what the philosopher Paul Feyerabend called epistemological anarchism, and what most working scientists would simply call a disaster for education.
The Decision
The trial lasted six weeks, from September 26 to November 4, 2005. On December 20, 2005, Judge Jones issued a 139-page ruling entirely in favour of the plaintiffs.
The court’s question was not whether Intelligent Design is true. A claim can be true but unscientific, or scientific but wrong. The question was about its status: does it qualify as science?
Jones concluded that Intelligent Design is “a mere re-labeling of creationism” that “cannot uncouple itself from its creationist, and thus religious, antecedents.” He grounded this in two arguments.
First: no recognition by the scientific community. There are no peer-reviewed publications supporting Intelligent Design in reputable scientific journals. All its literature appears in publications created specifically for this purpose, where proponents cite each other and generate the appearance of a scientific consensus that does not exist.
Second: non-falsifiability. Karl Popper argued that for a claim to be scientific, it must in principle be possible to show it wrong. Intelligent Design appeals to a supernatural agent whose existence cannot be tested by scientific methods. A supernatural explanation may turn out to be true — but that does not make it scientific.
The board members were also found to have lied under oath about their motivations. Jones described their conduct as an example of “breathtaking inanity.”
The school district was permanently enjoined from teaching Intelligent Design in science classes and ordered to pay over two million dollars in legal fees.
Why This Matters
The decision was a decisive defeat for the Intelligent Design movement, and attempts to introduce it into American public schools became significantly rarer afterwards.
The ruling did not ban Intelligent Design as an idea. Nothing prevents its discussion in churches, private settings, or online. What it banned was the teaching of a religious idea in public schools at taxpayer expense. A secular state has the right to say: this is not what we teach in our public schools.
That right matters because what children learn in school shapes what they believe as adults. The question of what goes into public education is not a minor procedural matter. It is a question about the kind of society we are building.
