Logic Can Be Fun - Or Can It? |

Read the following sentence.
"This statement is a lie".
Is the sentence a lie or not a lie?
If it's a lie, then the sentence is not a lie. If it's not a lie, then the sentence is a lie.
True or false, in place of lie, works too. |
Clarification/Follow-up by Bradd on 10/31/05 6:28 pm: slight correction:
for the quibblers - change "sentence" to "statement" - avoiding problems. Actually, either way is ok, but.........you know. Quibblers and all.

The problem is is that that is not logic by any method I am familiar with, For instance, both Peirce and Euclid’s procedure in proving theorems is to first present the theorem in general terms and then translate it into singular terms; next comes construction, which is followed by demonstration. Finally the ergo-sentence repeats the original general proposition. |
