On Dec. 20, 2005, Kitzmiller v. Dover Area School District—the trial that set the stage for a national debate on the constitutionality of teaching intelligent design (ID) as an alternative to evolution—was decided. In the lead-up to the trial, Michael Weisberg, professor of philosophy and chair of the philosophy department, and Paul Sniegowski, professor of biology, co-authored a letter on behalf of their departments in support of the teachers who argued against the inclusion of ID in the curriculum.
