Free Will is a being's ability to have control over its environment, future, and "destiny". A human being (presumably) has free will, and can therefore decide what to do; a rock does not have free will, and is a slave to the blind forces of physics.

Omniscience and Free Will

God is said to be omniscient, and this poses a special problem for free will: if God knows the future, that means that the future is predictable and immutable. This, in turn, means that our actions are predetermined. We may have pondered long and hard over which action to take, but the very act of pondering is as predictable as the execution of a complex computer program.

Note that this reasoning also applies to God: if God is omniscient, then he knows what he will do, and must inevitably do what he already knows he will do.

Some apologists argue that since God exists outside of time, he can have knowledge of everything that has and will be done without predetermination. An apologist might explain the situation in this way: Suppose Tom knows Susy quite well — so well that he knows if she sees a homeless man by the bus station, she will give him any change she has in her purse. However, even though Tom knows Susy will do this, she doesn't do it because Tom knows she will do it, but because she was going to do it anyway. Tom simply had the knowledge that she would do it. The difference between Tom and God, they say, is that God knows people better than they know themselves (being their creator), and so he knows, on a deeper level than Tom, just what Susy will decide to do in a given situation--again, not that Susy does it because God knows she will do it, but she does it regardless because that's what she decided to do.

Nevertheless, God's omnipotence causes the analogy to break down. If God has perfect knowledge of what will happen without his intervention, and his intervention is guaranteed to bring about a different result, then God has absolute control over what will happen. By refusing to intervene, God has effectively chosen the course of action. Also, Christian doctrine implies that God created both Tom and Susy while knowing everything that they would do in advance.

Christianity and Free Will

According to many Christian doctrines, God gave humans free will, and it was this that allowed Adam and Eve to disobey God in the garden of Eden. This position is also called the classic Arminian position.

Passages in the Bible that seem to support free will include John 3:16-18, which says that God sent His Son into the world to save humanity, and whoever believes in Him will be saved. This passage is about belief, it certainly doesn't say God has already determined who He wants to save and who He wants to damn. Also, 2 Peter 3:9 says that God does not want anyone to die in sin, but rather, He wants everyone to accept salvation and forgiveness.

"'What sort of choice does God offer,' argue the Arminians, 'if human beings lack the free capacity to respond appropriately?'" (Sparks, Kenton. God's Word in Human Words)

Predestination

Many Christian sects, such as Calvinism, hold that it has already been decided at or before your birth whether you will wind up in heaven and hell. Your actions do not change your final destination; through your actions, you can only demonstrate which fate has been chosen for you. Many Calvinists do not believe in free will.

Compatibilism

Compatibilism is a philosophical position that holds that determinism and free will are compatible.

Free will can be defined as the ability to choose an action. But how do we define "choose"?

Consider the way a human mind works: it takes input from the senses, processes it, and sends nerve impulses to muscles to direct the actions of the body. We do not know exactly how this happens, but it is nonetheless useful to think of the mind as choosing actions based on sensory data and memory.

This process of choosing may be deterministic, flowing ineluctably from the initial state of the universe and the laws of physics.

As an analogy, consider that many computer games have computer-controlled players. These use artificial intelligence (AI) to guide their actions and reactions to other players in their environment. Imagine a very sophisticated version of such a game, where the AI players can explore their environment, seek out other players, make long- and short-term plans, and so forth --- all just using conventional programming.

In the source code, there will be a function, or some chunk of code, that determines the player's actions based on data from the game environment, and "memory" from earlier points in time. Assuming that this code does not use a true random number generator, it is deterministic, in that its behavior can in principle be predicted a priori, given sufficient knowledge of the state of the program.

In practice, however, it cannot necessarily be predicted very far in advance: any error in measurement will tend to be magnified over time, so that any long-term prediction is bound to do no better than chance.

Problems

Many arguments for free will are given as resolutions to the Argument from Unbelief. That if God gave us evidence, we could not have free will:

If you accidentally swallowed poison and the doctor laid out seven syringes, only one of which contained the antidote, the other six would kill you, and told you which one was the antidote, did he take away your free will?

In addition, many people and groups throughout the Bible had direct evidence of God.

  • In the Old Testament, God routinely talked to people directly. Did Adam and Eve have free will? Did Moses?
  • What about Satan? In the bible, Satan is an angel of God, and yet he rejected God. This fact appears to blatantly contradict the idea that proof of God's existence would deny free will.
  • In the book of Exodus in the Bible, Pharaoh wants to, repeatedly, let Moses and his people go. However to demonstrate God's power he repeatedly "hardens his heart" and changes the pharaoh's mind directly. Does Pharaoh have free will?

If we are to believe that God, be it any God, has a special plan for us, in which he knows our future and coordinates it, then free will is impossible. Either God has a plan for us, or we have free will.
