On TV this morning I see that Calgary is going to approve an atheist ad on the side of its buses.
The ad strikes me as rather odd. The text as I recall is close to this:
There probably is no God. So stop worrying and enjoy your life.
An atheist claims that there is no God, so why on earth would they say that there PROBABLY is no God. This seems almost to be an agnostic heresy! If you are an atheist you should claim to know that there is no God. Imagine a Christian ad claiming that Jesus probably died for your sins or that Jesus is probably the Son of God!
Of course that there is no God could relieve some worries such as God punishing us for our sins or sending us to hellfire after we die. However, it is not clear why we should stop worrying about having incurable cancer or having lost all our retirement money in the stock crash simply because there is no God.
