### The Dead End - 08/01/2013

I was recently reading a great thriller and I was inspired by one of the chapters – “The Dead End”.
The main character crossed his path with a psychopath suicide bomber and the psycho told:

If what you say is a lie, I will press the button and blow the bomb.
On the other hand if what you say is a truth, I will detonate the bomb via the wires.

What should he say in order to get out of this ridiculous situation without bomb explosion?

Some may consider that if the main character stand stool and said nothing – that is a possible solution. But what if the bomb has a detonator anyway?

Another possible solution is to ask the psycho a question (this way we are going to avoid the lie and truth factor), but if he considers that as a cheat – he is going to push the button/ cross the wires.

We should construct such sentence – neither lie, neither true. The best and shortest solution I have found so far is using the Russel Paradox schematic. What if the main character says to the psycho – “I lie.” (“I am lying.”).
If he is saying the truth, then he is a truth teller and sentence like “I lie.” is contradiction. On the other hand if he is lying then “I lie” is false statement, therefore he is a truth teller and again we meet a contradiction. We can continue like that forever and we are not able to determine is this sentence is true or a lie. So this will really perplex the suicide bomber and we can avoid the damage for sure.

I also used a paradox for my answer, but slightly different:
If what you say is a lie, I will press the button and blow the bomb.
On the other hand if what you say is a truth, I will detonate the bomb via the wires.

So, what if I were to say "you will press the button"?
If it's viewed as a truth, he will use the wires, thus making it a lie.
However, if it's a lie, he will use the button, making it a truth.
