i fully agree w Hubert that lack of evidence does not prove the non-existence of something.[/QUOTE]
I’m sure that’s true, but that is the reason why, in law, the burden of proof is on the accuser, because it is impossible to prove a negative. Suppose that you are accused of a crime that you didn’t commit, and your defense is, there’s no evidence that I did it. Under your theory, you would be convicted. The fact that there’s no evidence doesn’t mean you didn’t do it. And there must be some evidence, otherwise it would be impossible to know that a crime had been committed.
That is also why what is claimed to be knowledge must always be supported by evidence, because without it, the most ridiculous notion can be regarded as not disproved. The Yoga Sutras explicitly states that the sources of valid knowledge are limited to perception, inference, and testimony of reliable persons. Samkhya goes even further, saying that testimony of reliable persons alone is not sufficient, but has to be supported by evidence. And we know that even inferences that appear to be logically correct can turn out to be false, so we need some kind of hard evidence in order for any assertion to be regarded as knowledge. If you are willing to accept a looser standard, you run the risk of acting on information that turns out to be false.
