An observation I made to my cousin at a family gathering yesterday.

I'm a theist in a manner that is functionally indistinguishable from atheism.

Also, my cousin defines "agnosticism" as the ACTIVE belief that the existence or non-existence of God is fundamentally unknowable, and that theism and atheism are a continuum, with "not knowing" being a middle point on that continuum, rather than "agnosticism." My wife doesn't go by that, because her definition of "atheism" is "a word that means absolutely anything a particular society needs it too", since her primary exposure to the concept is Kit Marlowe's "atheism", which would, these days, be counted as something closer to "Satanism."

But I'm an "agnostic" by my cousin's definition, because I define the metaphysical to be, y'know, metaphysical, and thus undetectable by physical means. Which means that it can have no observable or measurable effect on the physical world, which is why my theism is functionally indistinguishable from atheism.

I suppose Deism is a similar thing -- theism functionally indistinguishable to atheism.
