I think, at that point, you are using the term “absolute” incorrectly, and thus, leading me to assume an argument you didn’t intend to make.
As for your example: “practically assured” sure. Make it into a spike pit. There is a describable real circumstance where there is no guessing—the person is just gone.
But it is the relativism I am trying to address.
I still think you are right on deflation, mind you (and, considering our current issue is INFLATION, deflation, therefore is the inevitable result of anything that solves the inflation issue).
