The Problem of Omniscience

This is the last in a series of articles addressing Irish writer Michael Nugent’s “twenty reasons why God seems implausible”, as he explained them in a debate with Dr. William Lane Craig in March of this year.

During Mr. Nugent’s opening remarks he listed twenty or so reasons in rapid-fire succession, each leading into the next, and I felt that, cumulatively, they built a pretty strong case for his position. This article addresses the points from that list that dealt with God and the problem of omniscience.

Mr. Nugent’s 15th Reason: If this god is all-knowing then it knows the taste of strawberry yogurt. But if it doesn’t have a body or sense then how can it know the taste of anything?

This is a cute point, so I’ll start off with cute response: Christianity teaches that God is all-knowing, not all-tasting.

On a more serious note, this objection highlights one of Mr. Nugent’s misconceptions about God. As is common among atheists, and at times many Christians (including me!) he has adopted a bounded, small, anthropomorphic concept of God that bears little resemblance to the true God of Christianity.

When Christians talk about God’s omniscience (or any of His attributes, for that matter) we are not simply talking about man magnified. We believe God is holy. The Hebrew word for holy is “qodesh” which means “apartness, set-apartness, separateness, sacredness”. We believe God’s knowledge is holy; it is separate and different from our knowledge. God possesses knowledge in an entirely different way than we humans possess it.

“For My thoughts are not your thoughts, and your ways are not My ways.” This is the Lord’s declaration. “For as heaven is higher than earth, so My ways are higher than your ways, and My thoughts than your thoughts.” —Isaiah 55:8-9

When we say God is omniscient we’re not claiming He is simply able to store more facts and information about the universe in his mind than a human being can. The knowledge God has of the universe is independent of the universe for its existence. In fact, God’s knowledge of the universe is not a consequence of the universe existing. It’s the other way round; the existence of the universe is a consequence of God’s knowledge. As such, unlike human beings, His knowledge is not dependent on sensory experience, physical matter or even time. So in that sense God knew the taste of strawberry yogurt before the universe began.

Mr. Nugent’s 16th Reason: And if you respond to that (the 15th reason) by saying what it (God) knows is the truth of propositions then it is not all-knowing, it is less than all-knowing.

If I’m following correctly, Mr. Nugent is saying that the truth of propositions is only a subset of all possible things a mind can know, and therefore if the truth of propositions is the entire scope of Gods knowledge, God knows less than all things.

If that’s the definition one uses for “all-knowing” I could maybe grant Mr. Nugent’s point. But that’s not my understanding of God’s omniscience. I subscribe to a more broad view that is both logically coherent and biblically accurate: God knows all that can be known. We can split hairs ad infinitum about what exactly can and can’t be known. But at the end of the day what Christianity teaches is that whatever can be known is known by God.

Mr. Nugent’s 17th Reason: If this god is all-knowing, then it knows what we’re going to do in the future. Which means either we don’t have free will, or else the god has consciously created free agents that it knows will do evil.

Agreed. God has consciously created free agents that it knows will do evil. The reason for this, as explained in article #2 from this series, The Impossibility of a Changeless God, is that God’s highest value is love, not freedom from evil. Love is only possible when expressed voluntarily by free moral agents. Free moral agents necessarily have the power of choice. Which means the possibility of those agents choosing evil over good must exist in any universe in which love can exist. Therefore, a universe in which suffering and evil do not exist is a universe in which love cannot exist.

Which means there are no logical or moral problems with an all-knowing God creating free agents that He knows will do evil.  Especially since, as Christians believe, God can use even our evil choices for ultimate good.

“You planned evil against me; God planned it for good to bring about the present result—the survival of many people.” —Genesis 50:20

This verse above  exposes a side of God’s omniscience  that staggering in it’s implications; His knowledge so infinite it even includes the knowledge of what will be.  (Psalm 139)  That’s an astounding concept for our finite human minds to comprehend!  I recently heard an exchange on an episode of BBC’s Sherlock that I thought provided a small glimpse into the sort of knowledge God might have in order to know the future.

Sherlock Holmes: “Something’s coming.”

Mycroft Holmes: “Are you having a premonition, dear brother?”

Sherlock: “The world is woven from billions of lives, every strand crossing every other. What we call premonition is just movement of the web. If you could attenuate to every strand of quivering data the future would be entirely calculable; as inevitable as mathematics.”

That’s an interesting theory. It made me wonder if that might be way of understanding how God can know both what is and what will be.

Mr. Nugent’s 18th Reason: If this god cares about humans on planet earth then at a minimum it could have given us all the same information and the same moral messages.

Here Mr. Nugent is implying a sense of injustice because, in his mind, all human beings were not given the same information or moral messages. But is that true? I submit that both the Bible and human history reveal evidence that just the opposite is true; despite a vast range of differences across cultures, continents and eras, mankind shares a common knowledge about God and a common set of morals.

The Bible teaches that God can be known by any human being through nature:

“The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they display knowledge. There is no speech or language where their voice is not heard. Their voice goes out into all the earth, their words to the ends of the world.” —Psalm 19:1-4

“For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.” —Romans 1:20

Christians also believe that God has given everyone the same moral messages, that all of mankind was created imago Dei, in the image of God.

“So, when Gentiles, who do not have the law, instinctively do what the law demands, they are a law to themselves even though they do not have the law. They show that the work of the law is written on their hearts. Their consciences confirm this. Their competing thoughts will either accuse or excuse them.” —Romans 2:14-15

And history bears this out. For example, every major religion (and most atheists as well) subscribe to the golden rule.   In ancient Egypt they had a proverb that said, “That which you hate to be done to you, do not do to another.” In ancient China Confucius said, “Never impose on others what you would not choose for yourself.” This same concept appears in the ancient writings of India, Greece, Persia, and, of course, Judaism (Leviticus 19:18)  and Christianity.

“Just as you want others to do for you, do the same for them.” —Luke 6:31.

Mr. Nugent might claim this similarity simply shows that Christianity co-opted earlier pagan beliefs. But as I’ve analyzed in some detail in an earlier article (The Pagan Roots of Christianity) this commonality is actually strong evidence of the existence of objective morality and the truth of Christianity.

Christianity teaches that there is a divine awareness given to all men. (Ecclesiastes 3:11, John 1:9).  So if Christianity were true we would expect to find evidence of a common divine awareness running through human history, which we do. For example, the recurring dying-and-rising religious motif and the ideas of incarnation, death and rebirth are all part of the transcendent theme we Christians believe to be at the very foundation of the universe. And throughout history we see evidence of this common divine awareness among mankind.

“Men have differed as regards what people you ought to be unselfish to—whether it was only your own family, or your fellow countrymen, or everyone. But they have always agreed that you ought not to put yourself first. Selfishness has never been admired. Men have differed as to whether you should have one wife or four. But they have always agreed that you must not simply have any woman you liked.” —C.S. Lewis, Mere Christianity

So I would turn the question back to Mr. Nugent and ask, if God does not exist, why does mankind throughout history and across cultures share a common thread of objective morality?

Because God’s omniscience is not merely man’s intelligence magnified, but rather He knows all that can be known, and because history reveals evidence that mankind throughout the ages has been given the same information and moral messages, I believe Mr. Nugent’s arguments regarding the problem of God’s omniscience fail to provide sufficient logical reasons to support his premise that the existence of God is implausible. When taken as a whole, the evidence suggests just the opposite.
