John Quiggin at Crooked Timber discusses the increasing number of people who do not have a religious belief. Eli speculates:
In the last 50 years, the ability of humans (well at least some humans) to explain and manipulate our planet and particularly the biosphere which supports us has grown to the point where as a practical matter religion is irrelevant or confounding to that understanding. In the last 20 years the availability of that information has grown to the point where that knowledge is available to most. What remains for religion is ethics, but even ethics does not require religion although for many it is useful.
