Paul,
A1. Insufficient evidence ( by whatever standard ) for one thing does not allow us to conclude there will also be insufficient evidence ( by the same standard ) for something else.
I didn't mean A1 at all, let's move on.
[/INDENT]A2. What it seems you are really trying to get at is that if "seeing is believing" for one thing, then it should also be good enough for something else, and on the surface I would tend to agree.
Actually, and tellingly, it's exactly the opposite. I'm saying that if we do *not* accept "seeing is believing" for witches, we shouldn't do so for UFOs/aliens.
Because seeing an object is not the same as seeing an invisible supernatural power.
I'm confused, what are you saying is an invisible supernatural power, witches or aliens? I think you mean witches. On that basis,
1. you're still jumping the gun when you talk about seeing an "object." Seeing a light move around is not necessarily the same as seeing an object. Further data besides the perception of moving brightness is necessary to establish that the light emanates from an object (as opposed to reflections, multiple objects, etc.).
2. Where did the attribute of "invisibility" come from? Where were we talking about that? Why is a supernatural power invisible necessarily (by the way, strictly speaking, we're talking about the *results* of using a supernatural power, not the power itself.
3. All of this is vastly premature to establishing the general principle of whether seeing is believing. See immediately below.
To sum up. The idea that observation alone ( by anyone at any time ) is a standard that can be applied equally to any situation in order to formulate a reasonable position is faulty because the context of the observation, the quality of the observers, and the resulting information can all vary greatly from example to example.
This is better, but I have questions:
1. Without regard to specific cases, what are the general principles by which the context of an observation changes whether we accept an observation by a single person as reported or not? Understanding the difference between mere reportage or perception ("I saw a bright light.") and a conclusion ("I saw a bright object.") is crucial.
2. Without regard to specific cases, what are the general principles by which the nature of the observer changes whether we accept an observation by a single person as reported or not?
3. Not sure how "the resulting information" applies here in a parallel fashion as context and the nature of the observer.
