Probably and Perhaps
The Christian Science Monitor, on those anti-theist bus ads:
Much of the campaign's initial buzz centered on the assertion that God "probably" doesn't exist. Does this suggest a hedging of bets - a move past atheist dogma? Only partly.
Some organizers wanted a flat "there is no God" statement. Dawkins favored an "almost certainly no God" wording. But Ms. Sherine says that British advertising officials advised that a phrase less absolute and not subject to proof would ensure the ad did not run afoul of the advertising standards authority.
Clearly, the advertising officials have been reading their Joseph Ratzinger:
No one can lay God and the Kingdom on the table before another man; even the believer cannot do it for himself. But however strongly unbelief may feel itself thereby justified it cannot forget the eerie feeling induced by the words "Yet perhaps it is true." That perhaps is the unavoidable temptation which it cannot elude, the temptation in which it, too, in the very act of rejection, has to experience the unrejectability of belief. In other words, both the believer and the unbeliever share, each in his own way, doubt and belief, if they do not hide away from themselves and the truth of their being. Neither can quite escape doubt and belief; for the one, faith is present against doubt; for the other through doubt and in the form of doubt. It is the basic pattern of man's destiny only to be allowed to find the finality of his existence in this unceasing rivalry between doubt and belief, temptation and uncertainty. Perhaps in precisely this way doubt, which saves both sides from being shut up in their own worlds, could become the avenue of communication. It prevents both from enjoying complete self-satisfaction; it opens up the believer to the doubter and the doubter to the believer; for one it is his share in the fate of the unbeliever, for the other the form in which belief remains nevertheless a challenge to him.
Somehow, though, I doubt Richard Dawkins would concur.
