One must always remember that the burden of proof is on the person making the positive claim. Within science, this translates to the burden resting on presenters of a paper, in which the presenters argue for their specific findings.
I nicked the above quote from a Wiki page. It is true, as Farkel says that the burden of proof rests with the WTS. They are the ones asserting their beliefs and they must present the evidence to support them . I think that the term proof is not really accurate. How can you prove something that cannot be seen, touched or felt? A subject such as climate change demonstrates that the same "evidence" proves different things to different people, each equally convinced.
I read once a book about mankind's search for Truth...it reviewed all the main philosophers. I recall it said that truth can be arrived at by reasoning, logic, or by a simple realisation of the overwhelming ' right or wrongness' of a situation when judged by universal human values. I suppose when men like William Wilberforce saw the human misery of slavery , it was an evident truth that it should be abolished . He needed no other proof.
I felt like that when I looked with opened eyes at the concept of Armageddon . I by then knew worldly people who were decent honest and moral. It was an evident truth that my God in heaven would never slaughter them all (and their children) just because they were not one of J W's.. It suddenly seemed totally clear and obvious, and so then the J W beliefs had to be fundamentally wrong..
I know enough about Scripture and debating to know that one can never prove that to a determined dub . Believe me , I have tried . The family are sure that I have left my senses. But to me and to the rest of the remaining 6 billion or so in the world, the reasoning is clear, that they besmirch Gods name by that belief
So, can I prove that I am not heading for disaster at Armageddon, no - but the overwhelming evidence supports my conclusion and I am still waiting for any convincing evidence from those who propose the belief as truth...
Phew ! that was longer than I expected
