It isn't a new concept or even a new phrase. I THINK it is rooted in deism; it was a popular phrase used by a couple of the founding fathers in reference to an agnostic viewpoint in that they lacked the framework to remove entirely special creation, but that they wanted a way of not actually explicitly plucking (horse) apples of 'revealed truth' from the 'source' of such (horse) apples.
It has been co-opted by faux-intellectuals who who want to sound academic in their failure to recognize that it was only a begrudging concession given a lack of better alternatives to the idea, and would have been gladly abandoned had modern information been available.
It is today nothing but a thinly veiled appeal to nature, a claim that 'what has been is what should be', a derivation of ought from is.
