The media loves to invoke "the culture war" between science and religion, which in this country means evolutionary biology and Christianity. Neither is mentioned in this letter.
The article mentions that Einstein said he fell out of his religion at age 12 and "never looked back" but he still seem to experience the numinous: "But he never lost his religious feeling about the apparent order of the universe or his intuitive connection with its mystery, which he savored. “The most incomprehensible thing about the universe is its comprehensibility,” he once said."
And this statement is even clearer: “If something is in me that can be called religious,” he wrote in another letter, in 1954, “then it is the unbounded admiration for the structure of the world so far as science can reveal it.”
From the grave, Albert Einstein poured gasoline on the culture wars between science and religion this week.
