A defender of objective materialism in our current state of technology sometimes will fall into the trap, logically-speaking, of insisting that there is nothing that we can not measure, observe, detect, quantify, test, etc etc with our present technology, and end up asserting nonsense like "There can be no "God" because. . . . well, let alone because we can't objectively define or present a demonstrable thing answering to our definition. . . .nobody has scientifically demonstrated such a being."
This is like people saying, before the microscope was invented, that there were no germs or bacteria, or viruses.
This is like saying, before modern science developed the tools necessary to explore the ultimate nature of matter, that there are no "atoms" or indivisible particles which distinct characteristics. . . . . let alone sub-atomic particles. . . .
Well, I think science is good. From the time I was a child I understood that it was a system of exploration of things unknown, and in it's most important characteristics included a rule about reproducibility, meaning a result could be sufficient, rigorously described in terms of hypothesis, tools, equipment, methods, experimental design and conduct. . . . : to the extent that independent researchers could reconstruct the experiment and verify or disprove your results, and maybe propose other conclusions to your experiment than the one you prefer. . . .
That is what I understand as "Science".
I've always understood that religion is not conducted on those rules, and I've always defended the human being's right of belief. . . . it is essentially the same right as the right to question authority. . . . and it is the same right that scientists need to have to proceed with their business.
I haven't had time to read all the responses here, but I can tell it has been a productive discussion. . . .thank you all.
