In Edwards v. Aguillard, 482 U.S. 578 (1987), the Supreme Court held that a Louisiana law mandating instruction in “creation science” whenever evolution was taught in public schools violated the establishment clause of the First Amendment. The 7-2 ruling did not outlaw the teaching of creation science; it held only that states could not require science teachers to teach it.
Creationists had successfully prevented the teaching of evolution in several states until Epperson v. Arkansas (1968), when the Supreme Court overturned a statute prohibiting the teaching of the theory. In 1981 Louisiana Gov. Edwin Edwards signed the Balanced Treatment Act into law, which forbade the teaching of evolution in public schools unless students were also taught creation science.
Donald Aguillard, a high school biology teacher, joined by other public school teachers, parents, and religious leaders, charged that the law endorsed religious beliefs and lacked a secular purpose. The federal district and appeals courts agreed.
Law served no secular purpose, promoted religious belief
In the majority opinion of the Supreme Court, Justice William J. Brennan Jr. observed that the law served no clear secular purpose and promoted a particular religious belief, thus violating the establishment clause.
Brennan found the statute’s professed goal of protecting academic freedom deceptive because teachers were granted no more flexibility than they already had; the legislative history and the discriminatory preference for creation science over all other challenges to the theory of evolution revealed the real purpose of the law to be to promote a specific religious belief.
Moreover, the statute’s author repeatedly expressed his religious objections to evolution during legislative hearings. Brennan stressed that because attendance in public schools is mandatory, and schoolchildren are especially impressionable, the Court had to be especially vigilant when the schools become entangled with religious beliefs.
Applying the three-pronged test from Lemon v. Kurtzman (1971), used to determine if a law falls under the First Amendment’s prohibition of laws “respecting an establishment of religion,” Brennan found that the statute failed the “secular purpose” prong.
Scalia dissents, finds secular purpose
In a dissenting opinion, Justice Antonin Scalia accepted Louisiana’s assertion that its motives were not solely religious, finding a sincere secular purpose in its desire to foster a balanced understanding of the origins of life. Scalia then urged the Court to discard Lemon’s secular purpose test. It was futile, he argued, to try to determine subjective legislative intent given the multiple and often conflicting motivations behind a vote for any law.
The issue arose again, in Kitzmiller v. Dover Area School District (M.D. Pa. 2005), when a Pennsylvania school district required that a statement endorsing “intelligent design,” a form of creationism stripped of its religious references, be read to children in biology classes. A federal district judge held that the statement violated the establishment clause.Send Feedback on this article
