Atheists often face the charge that we have no true basis for morality. How can we, lacking a belief in a supreme law-giver, hold people accountable for their actions? Without God, isn’t morality just a matter of personal preference, with a nun’s opinion no better than a serial killer’s? Why should anyone follow anyone else’s standard?
Believers assert that only a transcendent, objective standard of morality, i.e. God, is sufficient for regulating human behavior. They say we need a standard that applies to all of humanity and is not simply one’s own individual opinion. However, a closer examination reveals that, even if divine morality can be shown to exist, it faces the very same shortcomings that believers ascribe to subjective morality.
Before they even begin the discussion, believers need to demonstrate that objective morality actually exists. More often than not, objective morality is taken for granted, but its existence is a claim that needs to be backed up. If believers want to point out deficiencies in subjective morality, that’s fine, but what if it’s all we have? We need to work with what we have here. You may wish you had a car that reliably starts and isn’t rusting through the floor, but if it’s your only form of transportation, you’ll have to use it in spite of its flaws!
What’s more, the objective morality asserted by believers simply wouldn’t work as well as they think it would. For one thing, God-based morality is not universal, despite the protestations of apologists. If the Christian God is held out as an objective source of morality, why should a Hindu care? Or a Buddhist, Taoist, Zoroastrian, and so on? If morality is based on any particular god, those who don’t believe in that god cannot be held accountable to that standard. In this way, a believer’s own “objective” morality falls short in the same way as subjective morality.
It gets worse. If we accept God is the source of morality, how do we then determine what is and isn’t moral? The problem is that objective morality is necessarily filtered through one’s own subjective human brain. If morality is revealed through a sacred text, then it comes down to the subjective interpretation of the reader. If morality is revealed through personal revelation, then of course this is subjective to the one who receives it. The end result is that every believer thinks they know objective morality, when in reality they can never be sure they have it right!
Observing the history of the church should make this obvious. Somehow, despite having access to the source of objective morality, Christians wind up on both sides of every major social issue. From abolition of slavery to feminism to civil rights to gay marriage to transgender issues, Christians seem to receive contradictory messages from their own God. How is this supposed to solve the “problems” of subjective morality?
The truth is that subjective morality is not as deficient as believers claim. Somehow, civilizations throughout history have converged on many of the same conclusions when it comes to moral behavior. There is no thriving modern society that allows for wanton murder, gratuitous theft, or unchecked rape. That’s because we’ve figured out that human beings thrive when we are all working together for the betterment of everyone. Barbarians don’t build skyscrapers, after all. Once we are no longer preoccupied with protecting our families and property, we can use the same time, energy, and resources for greater purposes.
Of course, there will be areas of disagreement as progress marches on, but the core tenets remain the same. Christianity is no improvement in this area. No one disputes the Ten Commandments, but practically all other issues are open to interpretation. All Christianity adds to the moral question is a dubious claim to divine authority and an unwarranted sense of superiority.
