You seem to live in a world where everything must be 100% true, or 0% true (i.e. completely false). This is incorrect. There are varying values of truth and as such there are various forms of evidence that allow us to have different levels of certainty of the truth. And really, you know this already: a story about a friend of a friend (of a friend) murdering someone is nigh worthless compared to the security footage at the grocery store showing the face of the person who murdered the clerk.dotoree said:What is evidence? People seem not to understand this most basic fact.
The knowledge of western civilizations rests basically 2 major kinds of evidence:
SCIENTIFIC EVIDENCE FOLLOWING THE SCIENTIFIC METHOD
Observations
predictions being fulfilled
logic, & a few others.
HISTORICAL EVIDENCE
Firsthand witnesses
Second hand witnesses
Archaeological data and a few others.
I'll grant you that historical evidence exists, but only with the caveat that it's one of the weakest form of evidence. Second hand witness and first hand witness are night worthless evidence. Indeed I even have a nice prepared list for such occasions (of reasons why you should not only be distrusting of other people's "testimonies" but of your own experiential memories):
Sure I'll certainly accept my friend's first hand account of his BLT for lunch at chile's as evidence that he did indeed have a BLT for lunch; however if I then see video footage that my same friend was actually robbing a bank for the duration of his lunch hour I would conclude that if he had a BLT it was in a hurry and certainly wasn't at chile's. The lesson here of course is that eye-witness account and second hand experience are perfectly fine evidence for non-extraordinary claims, but when they come in conflict with nearly any other kind of evidence it is that higher tier of evidence we accept.
But this isn't the whole picture; I accept my friend's claim he had a BLT for lunch because the claim that he had a BLT for lunch is so unimportant that it takes very little evidence for provisional acceptance. However when my friend claims he slept with Jessica Alba, I'm likely to require far more convincing evidence; in this case the claim, while certainly unusual and non-trivial, is ultimately unimportant, so the corroborating evidence of his friends who were with him in Vegas when he did it will probably be enough for provisional acceptance. However we can imagine a whole spectrum of claims from the trivial ones such as "I am sitting down right now" to the far more extraordinary claims such as "bill gates just wrote me a personal check for five billion dollars that I can do whatever I please with" and as the claim gets more extraordinary we require more *and* stronger evidence to support them. No matter how many times a friend tells me bill gates wrote him that check, and no matter how many of his friends tell me bill gates wrote him that check, unless I see objective and verifiable consequences of him actually having been given that check I will continue to not believe him.
So... I suppose in summary: I'll grant you that first hand and even second hand experience can be considered evidence, however it MUST be acknowledged that first and second hand experience are the lowest forms of evidence (for they are neither objective nor verifiable (only verifiable through other forms of evidence)) and that more extraordinary claims require not only more evidence but higher forms of evidence.
