Can anyone explain Axiom 5 of propositional logic to me? I can't follow it.

>> No.2479655

what is it, like if something is possibly true then it's necessarily possibly true?
Something that is prima facie unintuitive

>> No.2479671

i cant tell if that pictures a duck or a rabbit

>> No.2479672

>>2479671
It is neither a duck nor a rabbit.

>> No.2479674

>>2479671
duck obviously. for it to be a rabbit, the ducks neck doesnt fit anywhere

>> No.2479680

>>2479674
I'm with you, that is quite clearly a duck. I don't see how you could get rabbit out of that, unless you were only familiar with rabbits in some sort of vague way, like you read about them in a book once.

That's an example given by Wittgenstein (not sure if it was drawn by him or by someone else about his work, though), right?

According to him, it is both a rabbit and a duck. A duckrabbit, rabbitduck. It's meant to show the ambiguities of language.

rotate your head (or the picture mentally) 90 degrees.

>> No.2479696

>>2479688
I did, but it looks nothing like a rabbit, the 'ears' are weirdly positioned, there's no nose, or snout or anything, the eye seems oddly positioned. Its just not a rabbit.

>> No.2479697

>>2479688
...ok, but it's still a duck, just a bit upside down. as if it was interested in astronomy or something.

>> No.2479699

>>2479697
Maybe Wittgenstein was making a point about ducks being great astronomers, but no one will ever know because we can't speak duck... I mean they are skilled navigators, with all that migrating and such.

Never read wittgenstein, but probably Axiom 5 is:
>If you're a duck, rotate your head. You'll discover the stars.

>>2479703
Which rabbit? I do not see any in that pic.

>> No.2479717

>>2479714
Its such a shame that Wittgenstein never got to lay out the full structure of his revolutionary Duck Logic.

No, it is a duck, the fleshy feathered water birds are just pale imitations of this one true duck archetype.
