Two Bulbs of Truth

Logic Level 2

Is it possible for any mathematical question, to build a machine with two lights, yes and no, where the light marked yes will be on if it is true and the light marked no will be on if it is false?

The machine is not allowed to have both lights on.

  • The problem is a slightly trick question supposed to be answered from the Classical Logic Point of View
Yes No

The classical logician believes that the statement is either true or false,but never neither or both. So, he can do the following:

Just build two machines, one that has the yes light on and one that has the no light on. You now will have built the machine that was required, even if you do not know which of the two it is.

You can the both light off since it is not stated.

I simply voted yes because I used "Classical Logic'" and I do believe it can be done. Nothing to it.
