Are there instances (disregarding logical impossibilities) where we can make a positive assertion regarding existence of an object/ability. Or do we always have to say "I don't believe flying spaghetti monsters exist." instead of "Spaghetti monsters don't exist."

Is it philosophically incorrect to say "Humans cannot telekinetically fly to the moon"?

I'm pretty sure I can claim that there is no elephant in my garage because when I go to the garage, there is no elephant there. I can (and do) positively assert the absence of an elephant in my garage.

Edit: So there are clearly cases in which the absence of evidence can be used to justify a claim.

I'm not sure this is the same thing as the examples in the OP, in that it is a specific claim, and not a general one.

There is no black hole of mass 10^24 kgr in my room either or i wouldn't be here lol!

Proton doesnt have lifetime 10^5 sec either! The positive version is that proton has lifetime over 10^5 sec since i am still alive since this morning with more or less same features.

I like Seinfeld.

Point taken. How about the claims in the OP?

I guess it's of note that both Masque's and Aaron's claim both involve a location. Can we ever make a positive assertion of nonexistence without referring to a specific location?

I'm only asking because I think it gives off an incorrect connotation to merely say "I don't believe in leprechauns". It's giving implicit credence to the notion that they might exist that doesn't happen when you say "Leprechauns don't exist".

Yes, you can say "experience is". Falsifying it would prove it, so there you go.

It also means empiricism is pretty much the only philosophical approach which doesn't require unprovable assumptions. Yay.

No, you can do either in every day English, everyone knows what you mean.

Of course if you say something like "Spaghetti monsters don't exist." on an internet forum like SM&P you will get nitted to death.


I guess it depends what branch of philosophy. For any statement I am sure you can find some branch of philosophy that will allow you to nit it.

Would be awesome if someone could explain how this works to me; is it because one can never prove something, only disprove it.

With flying spaghetti monsters, it can never really be disproved as one never has enough information to actually infer that there isn't flying spaghetti monsters, as one's sources simply may not have that particular location covered or ability to detect them(maybe they're from outer space or invisible)

Close?

People say "spaghetti monsters don't exist" in everyday conversation?

Not that often, not that I implied they did, just if someone did say it in everyday conversation it would be understood.

However similar stuff does happen. For instance only today someone claimed to have pocket fours for a flopped set, and another player at the table asserted that his 'pocket fours did not exist'. Everyone seemed to understand what was meant.

No you cant.

This depends on what you mean, if you mean that, definitionally, it doesnt, then thats the same as saying "except logical impossibilities." If you simply mean we've never observed a proton with a lifetime of 10^5 sec" then you cant claim its impossible.

There is no pair of integers a and b such that a/b = sqrt (2).
