Invariably when I get into a discussion, be it on religion or ghosts or some other supernatural phenomena, someone will eventually accuse me of calling them a liar. “Are you telling me,” they’ll begin to ask with an air of righteous indignation, “That I don’t know what I saw?” Yes, I’ll reply. That’s exactly what I’m telling you. I don’t doubt you believe you saw what you think you saw, but I doubt that you actually saw what you claim to have seen. Quite often that’ll put an end to the conversation as the other person stamps off in a huff over the outrage of having his perceptions challenged.
The next time I come across a conversation like that I’ll point to this video clip of from Cosmic Quandaries with Dr. Neil deGrasse Tyson. In it he’s just been asked if he believes in UFOs and he goes on to explain the argument from ignorance and why your eyewitness account isn’t enough for scientists to accept by itself. Check it:
Good stuff and points made with a bit more tact than I’m usually capable of.
Update: Looks like you can watch the whole thing on YouTube.
