Pascal's Wager (or, if you prefer, Pascal's Gamble) is a logical argument and is not a "maxim."<quoted text>
Actually it's called both 'Pascal's Wager' and 'Pascal's Gamble', depending on your region of origin. And I am familiar with the conceptI have taught it. It is called many other things in regional colloquialisms, and it's a concept that predates both of our prior monikers. In better words,'it's a rather old maxim' that was boiled down for 'comfort'.
And, if you think about it for a while, Pascal's Wager has a devastating logical error. In other words, there is an error in the fundamental assumption, and thus the conclusion is untrue. That does not stop illogical people from pretentiously citing Pascal's Wager, thinking that they are wise.
