Yes, they are all nice faces, but beyond that, they are all trustees of Project Reason, an organization dedicated to spreading science and secular values, founded by Sam and Annaka Harris. Christopher was a trustee.
Project Reason is a 501(c)(3) nonprofit foundation devoted to spreading scientific knowledge and secular values in society. We seek to encourage critical thinking and wise public policy through a variety of interrelated projects. The foundation can convene conferences, produce films, sponsor scientific studies and opinion polls, hold contests, publish original research, award grants to other charitable organizations, and offer material support to religious dissidents and public intellectuals — all with the purpose of eroding the influence of dogmatism, superstition, and bigotry in our world. While Project Reason is devoted to fostering critical thinking generally, we believe that religious ideas require a special focus. Both science and the arts are built upon cultures of vigorous self-criticism; religious discourse is not. As a result, religious dogmatism still reigns unchallenged in almost every society on earth—dividing humanity from itself, inflaming conflict, preventing wise public policy, and diverting scarce resources. One of the primary goals of Project Reason is to change this increasingly unhealthy status quo.
