Talk:Paradox of entailment

From Wikipedia, the free encyclopedia

It's a perfectly valid and sound argument.

if

2 + 2 = 4

and

2 + 2 = 5

then

2 = 1

Therefore, since Elvis and the Pope are two people, Elvis and the Pope are one person.

This makes no sense at all and it is completely idiotic. 2 plus 2 does not equal 5, end of story. To base an argument on something like this is stupid. This isn't a paradox, it's just stupid.

This is an old joke. Recently someone added something similar, but with the added line:

Similarly, any arithmeticaly inconsistent premises can be used to construct the statement "1=2". Then the same argument shows that P = Q, for any two satements P and Q.

There is a little bit of truth to this last bit, but not much. Not enough for the article, even in the state it is currently in. 192.75.48.150 20:15, 25 August 2006 (UTC)
