The basic idea that nature can be understood, if we look carefully enough and avoid resorting to the supernatural
... was originally predicted as a result of a rational Creator, not the lack of one. Arguably it was the wrong deduction given the premise, but still.
Other way around, I would think. References? Everyone was a theist back in the days of Roger Bacon, they had to be. So did anyone decide, "God is rational", and then deduce "we can attain all manner of powers if we just investigate how things work"? Or was it a case of discovering the effectiveness of empirical investigation, then deducing the rationality of God -- either from genuine faith or just as a way of avoiding charges of heresy?
If an atheist from any period up to the present could have gained information not already discovered (but that we now know, of course) why does this effect mysteriously vanish when we move from a hypothetical past atheist to actual current atheists living in the modern world?
Because, as I said, it's been done, mined out before open atheism was even a thing. "There is no God" has precious little implication beyond "this is not a benevolent universe and it's up to us to figure everything out and save ourselves." In contrast, "There is a God (of the Christian/Jewish/Muslim type)" leads to the false prediction that the universe is benevolent, rescued by postulating hidden or mysterious benevolence. The theist can take their pick of it being understandable ("the rational works of a rational God") or not ("mysterious ways"), although the former is in some conflict with the postulate of benevolence passing human understanding.
Damn you, source amnesia! shakes fist
Here's a small piece of corroborating evidence while I try and remember:
...‘Men became scientific because they expected Law in Nature, and they expected Law in Nature because they believed in a Legislator. In most modern scientists this belief has died: it will be interesting to see how long their confidence in uniformity survives it. Two significant developments have already appeared—the hypothesis of a lawless sub-nature, and the surrender of the claim that science is true. We may be living nearer than we suppose to th

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
