[Antonello]

Sometimes I get the impression I am wasting my time debating with morons. If you have a theory that pigs fly, then your theory would obviously be falsified if you ever see a pig fly. So my alternative theory, that "pigs can't fly" would be falsified if we ever observed a pig fly. My "prediction," therefore, is that we will never see a pig fly. Yes, that's a prediction that something will *not* happen. So what?

I'm sorry to jump in, but I couldn't help but notice a slight error in this paragraph. Specifically:

...If you have a theory that pigs fly, then your theory would obviously be falsified if you ever see a pig fly....

Wouldn't that be:

'If you have a theory that pigs fly, then your theory would obviously be falsified if you ever see a pig not fly.'

Of course, since the theory isn't that all pigs fly all the time, not even that falsifies the theory.

My theory says that pigs fly ... but only when no one is looking.
