I saw this some while back in the comments on some web site:
When religious laws surmount mercy & reason , we must remember that religion was written thousands of years ago, when knowledge was in it’s infancy.
I thought it was striking in the way it illustrates the vast gap, more vast than usual, between the writer's estimation of his own grasp of the subject and the reality of both the subject and his grasp of it. I mean, not only does he not know, but has no idea at all that he doesn't, but is quite sure that he does. The apostrophe is a nice finishing touch.
It's been apparent for many years now that the association of atheism with education and the use (however mistaken) of reason no longer exists. Atheists are just as likely as believers to have come to their views without much thought--to be merely following the crowd, for instance. It's just a different crowd.
It occurs to me now to wonder if English is the commenter's second language. "Religion was written"?? Even if that's the case, it wouldn't improve the remark much.
