An Old Man Once Told Me, "Some Things That Are True Are Not Very Useful."
Newton vs Einstein
Useful lie and uncomfortable truth collide.
Aspects of Newtonian physics (ex: mass of moving objects remains constant) have been disproven by Einstein's relativity (ex: mass increases with acceleration). Yet, engineers and everyday people still operate by Newton's laws and they serve us well. I am not saying that we do well in spite of adherence to Newtonian physics, but rather because of adherence to his laws. Some things that are not true are indeed useful. The Wager
Roll the dice on truth
I believe this was implied by Blaise Pascal in his Pensées, relating to belief in the existence of God. "Pascal's Wager" can be summarized like this: - "God is, or is not."
- There are some people "made in such a way that [they] cannot believe [in God's existence]."
- It is best for these people to "bet" that God does exist.
- Because if God does exist and the person believed; eternal reward. However, if the person did not believe; eternal punishment.
- And if God does not exist, then the person had a good life anyway (because of his belief, however erroneous) and there was no harm in believing that He did.

The Tie-In
Does it hurt to believe in a lie?
Is this true (that there is no harm in believing such a falsehood)? Are some lies useful? And if they are, is it morally permissible to use them?
What do you think?
Are lies ever useful?

Pascal actually was just trying to get people to stop arguing about it. He wasn't coming down on one side or the other.

Pascal's wager is idiotic for two reasons
- if the all-knowing God exists, he would have certainly realized that you were attempting silly tricks on him instead of believing honestly; so you lose the wager
- if the all-knowing God does not exist, you've wasted lots of time and resources doing silly stuff rather than living your life to the fullest (it's certainly not a cost to be taken lightly)
So either way you are the loser if you accept Pascal's wager.
