Mike, I agree with the thrust of your post, but I believe that "belief" is an assessment of a probability based on persuasive but incomplete knowledge, i.e. "it has always been true in the past and there is no reason to believe it will be different in the future." We believe in the "constancy" of universall laws, but we also believe in the "uncertainty effect" in quantum.
I got to disagree with the use in that method because you could delete the word "believe" all together.
"it has always been true in the past and there is no reason to believe it will be different in the future."
"it has always been true in the past and there is no reason it will be different in the future."
See how the use of "Belief" makes the sentence weaker?
Replace with "knowledge".
"it has always been true in the past and there is no knowledge to the contrary that it will be different in the future."
In the wording "We believe in the "constancy"... Do you think it is stronger or weaker than "There is "constancy" in universal laws where there is "uncertainty effect" in quantum?
