How could you believe that an octopus, no matter how polite and moral, always tells the truth? Is it actually possible to tell the truth all the time? | |

| Feb 18, 2014 at 13:30 | comment | added | Julia Hayward | "So an octopus can only know how many legs other octopuses have." Since we've suspended reality enough to have talking octopusses, who's to say these four haven't asked a truth-telling companion how many legs they have... | |

| Feb 17, 2014 at 12:56 | comment | added | Peter Brooks | They can only see two or three legs if they are in front of their eyes. They have no direct control over their legs, so it isn't clear that they can move their legs in front of their eyes, and they don't have mirrors. | |
| Feb 17, 2014 at 12:08 | comment | added | Martin Smith | Why wouldn't an Octopus simply be able to see how many legs they have? | |
| Feb 17, 2014 at 10:45 | comment | added | Mr Lister | You mean the first one, who sees a total of 20 legs on the others, guesses that he himself has 8 legs and so says 28, because that would have been the true answer if he did have 8 legs? Yes, makes sense. | |
