Nonetheless, Dowd's views do bring solace to some, going by reactions from parishioners who claim that a scientific perspective has helped them come to terms with their follies of the past. For some at least, the recognition of genetic and biochemical frailty is a healing act. Last fall, for example, after Bob Miller, an 81-year-old man, heard Dowd's sermon at a Unitarian church in Pensacola, Fla., he felt his guilt over a string of affairs from four decades ago melting away. "I could never quite understand why I had behaved that way," says Miller, who was climbing the corporate ladder when his infidelities began, leading to the breakup of his marriage. When Dowd began talking about viewing moral lapses against the backdrop of evolution, "suddenly a light went on inside my head," Miller says. His rising status at his company, he concluded, had probably contributed to increased testosterone. "I think the physical change in my body was so strong that it completely overpowered any moral teachings and religious beliefs I had," Miller says. "It was still inexcusable, but it made more sense."
