MarsColony_in10years: Yeah, thanks. Sorry about the nitpicking.
ChristianKl: I think an infinite number would allow you to rule out the possibility (of a black swan that is). I thought that the problem was simply that we could never get an infinite number of them, but then again: I’m not certain.
To the extend that the word infinitive makes sense, you can see an infinitive number of white swans without seeing a black swan.
