Ruby's Greek Thread

[Anton]

I would suggest that, logically, if you can't prove it is Greek, you can't prove it isn't Greek.

There's some fallacy here. Suppose you encounter an unknown animal. You are considering the question of whether it is a cat or not. The animal in question has wings while cats are known to be devoid of wings. Hence you can't prove that it's a cat, while, at the same time, you can prove that it is not a cat.
