Resumo

In this paper, an argument by Fisher (2004) is formalized and evaluated by means of some tools of classical logic. The argument presented by Fisher is a version of a piece of reasoning of great historical importance known as Pascal’s Wager. According to Fisher, “this is a fascinating piece of reasoning. It is complex and important and hard to handle”. Here is shown that, although formal logical analysis has limitations to evaluate everyday deductive arguments, it is perfectly capable to formalize and evaluate Fisher’s argument. This should show that its usefulness is undeniable.
