Alice and Bob Make a Wager

Critique of Apologetics, Thought Experiments

Thought Experiment


Alice and Bob believe in contradictory theistic gods, Theo and Uja respectively. Both faiths require belief in their mutually exclusive gods or dire consequences are at stake.

Carol does not believe in a god, but she is an open and honest seeker of truth. Carol has separate conversations with both Alice and Bob in which the believers try to convince the non-believer why she should believe.

Independently, Alice and Bob both use variations on Pascal’s Wager to try and convince Carol to believe. However, Alice wants Carol to believe in Theo but Bob wants Carol to believe in Uja.

Alice and Bob’s argument goes something like this:

If you are right about the nonexistence of God and I am wrong,

I lose nothing.

If I am right about the existence of God and you are wrong,

you lose everything.


  • Why might Carol not be convinced by either?
  • What happens when Alice and Bob talk to each other?
