The Economic Dilemma of Eternity: Is Belief Rational?

Imagine 13.8 billion years of non-existence before birth, trinc by an 80-year life, and then non-existence for a period equivalent to that number multiplied by a 1 trinc by 67 zeros. This is the premise dividing those who view religion as an infinite life insurance policy from those willing to bear the opportunity cost of a dogma-free life.

While seemingly philosophical, this debate has a clear economic reading: if the expected value of faith is infinite (eternal heaven) and the cost of disbelief is infinite (eternal hell), rationality demands belief—provided the probability of God’s existence exceeds zero. However, issues of intertemporal discounting and uncertainty regarding which deity is correct arise here.

Pascal’s Infinite Utility
Pascal’s classic argument takes on new dimensions when considering the figure of 10^67 years. If Paradise promises eternal happiness, any positive discount rate reduces it to a finite present value only if the horizon is finite. But with an infinite horizon, the present value remains infinite for any discount rate less than one. Some analysts describe religion as a "benzodiazepine" to avoid madness in the face of cosmic insignificance. Others argue atheism is the braver stance: accepting no reward after death and viewing life as a blink without transcendent meaning.

Discounting Problems and Competing Gods
If multiple religions offer contradictory promises, the probability of choosing correctly dilutes. Furthermore, if faith requires costs (time, money, sacrifices), the investment may not pay off when the subjective probability of the true god existing is low. The agnostic position, often criticized as hedging bets, attempts to minimize costs while keeping options open. Yet, economic analysis shows that in the presence of infinities, any positive probability generates an infinite expected value, rendering indifference irrational.

The debate also incorporates the simulation hypothesis: if we live in a computer, the "programmer God" might be external, and death merely a logout. This version reduces the problem to a dimensional shift rather than a matter of faith.


The unanswered question is whether the human mind can handle concepts of infinity in decisions with eternal consequences. Time, like gold, seems to lose value as the horizon extends to infinity. Meanwhile, forum discussions continue, and as one comment noted, Spain's Tax Agency (Agencia Tributaria) might be the entity that truly knows eternity.
