0 Guest Posted May 30, 2008 Report Share Posted May 30, 2008 Um... I guess you mean that "No Horse" and "One Horse" are the names of horses, and not the amount? Is this a riddle or a statement? Quote Link to comment Share on other sites More sharing options...
0 Guest Posted May 30, 2008 Report Share Posted May 30, 2008 No horse has five legs. One horse has four more legs than no horse. Therefore, one horse has nine legs. No Horse is the name of the horse and No Horse has five legs therefore One Horse (which is also a name) has four more than five which is nine legs.

0 Guest Posted May 30, 2008 Report Share Posted May 30, 2008 And how is that a riddle exactly? It's a logic problem, Darklighter is making a logic induction that is false and is asking implicitly why it is false. I think that the first assumption can not be taken as a base for this implication, therefore all the statement does not make sense! Like Writersblock said: "No horse has infinite legs... therefore one horse has infinite +4 legs" which means that one horse has infinite legs (infinite + 4 = infinite) which is absurd coz we started with the assumption that no horse has infinite legs!!! I hope I was clear in that... Quote Link to comment Share on other sites More sharing options...
0 Guest Posted May 30, 2008 Report Share Posted May 30, 2008 (edited) No horse has five legs. One horse has four more legs than no horse. Therefore, one horse has nine legs. So the horse has two legs at the back and fo(u)r-legs at the front Three small riders of which one has a leg missing the answer is it's a eleven legged, four headed talking horse (Mr Eds) edit=can't count or spell Edited May 30, 2008 by Lost in space Quote Link to comment Share on other sites More sharing options...
0 Guest Posted May 30, 2008 Report Share Posted May 30, 2008 And how is that a riddle exactly? This isn't a riddle. This is a classic example of the problems with propositional logic. Using the phrase "no horse" in the first sentences to mean two different things can lead to unintended consequences with a crazy conclusion (that a horse has 9 legs). The first sentence is true using the phrase "no horse" to mean "not true for any horse". However, the phrase "no horse" needs to mean "none exist" for the second sentence to be true. Putting them together, with the two different meanings, leads to a 9 legged horse. Interesting, but not a riddle. Belongs in a different forum.

It's akin to me saying, "Nobody's perfect, but I'm just a nobody. So I'm perfect." Quote Link to comment Share on other sites More sharing options...
