We shouldn't retreat from the accomplishment -of not being religious

 As science and religion began to go their separate ways—a process that accelerated with the work of Darwin—science became secular.

 “The elimination of God-talk from scientific discourse,” writes historian Jon Roberts, “constitutes the defining feature of modern science.” Weinberg would have agreed. 

As he told an audience in 1999: “One of the great achievements of science has been, if not to make it impossible for intelligent people to be religious, then at least to make it possible for them not to be religious. We should not retreat from that accomplishment.”
