On Oct. 18, five alumni groups announced the creation of an organization to stand up for open inquiry: The Alumni Free Speech Alliance. This group consists of alumni. Why?

Because with rare exceptions, everyone else may feel too exposed to attacks to take a stand against campus culture. Our experience is that the few student free-speech groups don’t have many members (Princeton’s has about 20). Champions of free speech among faculty are badly outnumbered, even as many left-of-center professors are starting to realize that they too can be brutally canceled by the mob. Those few students and faculty who speak up often feel isolated and exposed.

University trustees, presidents and other administrators are also usually mired in the toxic campus environment, which responds to heresy with attacks. Most have either been cowed by or genuinely believe in a woke orthodoxy that sees free speech as an inconvenient disruption.

That leaves alumni as the only university stakeholders with the numbers and clout to lead the defense of free speech, academic freedom and viewpoint diversity in campus environments. Free speech and academic freedom are fundamental to the advancement of knowledge and to the success of our colleges and universities. Will all teaching and research at these schools soon be subject to a mandated orthodoxy? Will parents keep paying to send their children places where the fundamental elements of learning are suppressed? These institutions constantly seek alumni involvement and contributions. Alumni have the ability and duty to demand that their schools maintain the reasons for which they were created. But to be effective, alumni need to organize.
