Susan Jacoby writing in the New York Times:
"It is primarily in the face of suffering, whether the tragedy is individual or collective, that I am forcefully reminded of what atheism has to offer. When I try to help a loved one losing his mind to Alzheimer’s, when I see homeless people shivering in the wake of a deadly storm, when the news media bring me almost obscenely close to the raw grief of bereft parents, I do not have to ask, as all people of faith must, why an all-powerful, all-good God allows such things to happen.
"It is a positive blessing, not a negation of belief, to be free of what is known as the theodicy problem. Human “free will” is Western monotheism’s answer to the question of why God does not use his power to prevent the slaughter of innocents, and many people throughout history (some murdered as heretics) have not been able to let God off the hook in that fashion.
"The atheist is free to concentrate on the fate of this world — whether that means visiting a friend in a hospital or advocating for tougher gun control laws — without trying to square things with an unseen overlord in the next. Atheists do not want to deny religious believers the comfort of their faith. We do want our fellow citizens to respect our deeply held conviction that the absence of an afterlife lends a greater, not a lesser, moral importance to our actions on earth."
I found the entire article enlightening.
