Hi, Mike--my turn to welcome you and admire your fish. I was on South Cape Cod Beach last week watching surfcasters throw 2 and 3-foot bluefish back...
Their freezers were full, they said. The bastards.
Facts are concrete ... what you believe does not change the facts.
What you believe can change your body. Those changes can impact you and the world around you dramatically.
Circumstantial evidence might be interpreted incorrectly ... factual evidence cannot, no matter what you believe.
Surely you don't mean that literally: we are regularly treated here to the misinterpretation of factual evidence.
I agree with MrHambre that facts are socially/culturally determined.
Whose perceptual apparatus and mindset should be used to determine which "facts" are cast in concrete? Sadly, we lack an heroic "Objective Man" and have to settle for a consensus arrived at by best methods and efforts, all of them falling short of the Glory of Fact.
