Tuesdays at 5 PM in W20-450 (Fall and Spring semesters)
Connect through thoughtful, friendly discussion with atheists, secularists, and secular humanists. Explore topics ranging from philosophy to science to current events. The purpose of our discussions is to learn from each other rather than to debate. We also provide snacks and drinks, and occasionally play board games or go on an outing. Please check the event calendar on this page to confirm each week's programme. Jerry DeWitt

Sagan Day Talk


We host notable atheist speakers -- including Steven Pinker, Jerry DeWitt, Aaron Adair, and Faisal Saeed Al Mutar -- to raise awareness of issues facing the non-religious, and to educate our community in intellectual counterarguments to religious assertions -- our Course 0 series. We ourselves engage in dialogue with religion-affiliated organizations to present and defend the atheist and secularist perspective. And we have special events to support and inspire non-believers from specific religious backgrounds through discussion and storytelling -- our Out And Out series. Al Mutar Lecture
Counterapologetics with Adventists


We do service projects to help the community, care for the environment, and raise money for charities. We have partnered with the Greater Boston Food Bank, the Prison Book Program, and the Woods-Mullen Shelter. We have also done events to care for the environment, like collecting recycling and cleaning up the Esplanade. Food Bank Service
