Rev. Michael Dowd describes himself as “a religious naturalist.” The evolutionary theologian and author will be giving the Lyceum Lecture at Unity Temple, 875 Lake St., this Friday, Sept. 5, at 7 p.m. 

“Humans, unwittingly, have become a planetary force,” Dowd writes. “We are changing, irreversibly, the very climate of our world. Henceforth, any actions we take as individuals and societies will be done in the new light of climate change. What vision will carry us forward through such times and inspire us to work together? What vision will charge us with a sense of heroic purpose that the future is, indeed, calling us to greatness?” 

Dowd and his wife, Connie Barlow, a science writer, have delivered 2,000 talks since 2002, including one to the United Nations.

Admission is free.

The discussion is on the same day that environmental activists will arrive in Oak Park, just in time for the Chicago Climate March on Sept. 6.
