Atheists Can Be Moral, Too

Can There Be Objective Morality without God?

Believers commonly assert that, without God, there can be no “objective right and wrong.” Yet, such an assertion ignores what it means to be objective. When we identify something as objective rather than subjective, we’re saying it can be observed in the real world. We’re saying it can be perceived, or conceived through reason applied to our perception. Even the most fervent believer must confess that God transcends our human perception, and therefore cannot be cited as a source of objective morality.

The appeal to God as a source of morality proceeds from our recognition that some standard must be applied to our decision-making process. Otherwise, anything goes. In his book Loving Life: The Morality of Self-Interest and the Facts That Support It, author Craig Biddle addresses this problem:

The problem is not: “If there is no God, anything goes.” The problem is: If there is no objective standard of value, anything goes. If there is no rationally provable standard of value, there is no way to defend with moral certainty what is right or to condemn with moral certainty what is wrong. The alternative is not religion versus subjectivism, but reason versus subjectivism – and the secular subjectivists know it.

The secular subjectivists Biddle references are those within the culture who reject religion as a source of morality, but make no effort to replace it with anything concrete. They suffice to say that morality emerges from social convention or rests in the eye of the beholder. What is right, they claim, is what makes you feel good, or what results in the greatest happiness for the greatest number, or what serves the “common good.”

How Do We Respond to Secular Subjectivism and Moral Relativism?

Believers offer our appeal to God as the source of “objective morality” in answer to such blatant subjectivism or moral relativism. Right and wrong can’t be left to whim, we argue. But our appeal to God doesn’t solve the problem.

Subjectivism – whether personal, social, or “supernatural” – wreaks havoc on human life and happiness. Until we can answer it with (genuine) moral certainty – that is, until we can show that morality is based on facts – it will continue to do so. From muggings and rapes, to school shootings and truck bombings, to concentration camps and gulags, to religious “inquisitions” and divinely inspired acts of terrorism – all such mayhem is caused by subjectivism. And the is-ought dichotomy is what makes subjectivism seem plausible.

The “Is-Ought” Dichotomy

This “is-ought dichotomy” is the philosophical dead end in which believers spar with secular subjectivists. Our culture has given up on the task of discovering a truly objective morality, because we have largely bought into the notion that values cannot be derived from facts, that we cannot discern an “ought” from an “is.”

The Moral Abyss of David Hume’s Philosophy

Biddle points to the eighteenth century philosopher David Hume as the originator of the is-ought dichotomy. Hume taught that it is logically impossible to transition from observable facts about the natural world to a code of conduct or set of values. The problem with Hume’s conclusion is that it leaves us with nowhere to go, with no moral anchor nor any means to discover one.

The is-ought gap represents a moral abyss. If we care about human life and happiness, we need to bridge it. We need to ground morality in reality; we need to discover a rationally provable ultimate end – a standard of value derived from observation and logic.

Christian believers should not feel discouraged or threatened by this. Indeed, scripture exhorts us to look to creation for general revelation regarding the character and nature of God. Paul says in Romans 1:20:

For [God’s] invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.

The Natural World Provides Guideposts for Appropriate Human Action


The primary such guidepost is a standard of value from which to judge the appropriateness of all other conceived values, an end unto itself which all other ends support.

An end is a goal toward which one acts; a means is the action one takes toward a goal. For instance, if a student studies in order to get an education, the education is an end toward which his studying is the means. Likewise, if a person works in order to earn a paycheck, the paycheck is an end toward which his work is the means. But notice that such goals are not ends in themselves. A student gets an education so that he can pursue a career – which he pursues in order to support himself and earn a paycheck – which he earns in order to buy things – which he buys in order to use for various other purposes – which he pursues in order to accomplish still other goals – and so on. Each end presupposes another. So where does it all end?

If we are to establish an objective, fact-based morality, we need to discover a final end – one toward which all of our other goals and values are properly aimed. Such an end is by that fact our standard of moral value – the standard against which we can objectively assess the value of all our choices and actions. So the question becomes: What is our ultimate goal?

When we identify this ultimate goal, the question of what we ought to do becomes objectively answerable. That, and only that, is how we discern an objective morality.

As this series continues, we will present and evaluate this objective standard of value. Biddle offers it as an alternative to religion. But one need not be an atheist to accept it. Indeed, the discovery of an objective standard for moral action should embolden the believer and deepen our appreciation of God.

As a father, I may answer any challenge from my son with the proverbial “because I told you so.” In doing so, I don’t offer an actual reason. I merely assert my authority. While that authority proves legitimate, my ultimate desire for my son is that he one day understand why my instruction and rules serve his interest.

Similarly, the appeal to God as a moral authority may prove correct, but says nothing of why his prescriptions are good for us. A consideration of objective morality works to bridge that gap.
