But we're saying the source is unconscious, rather than conscious. Ethically, it's a whole big mess of worms. Having no free will implies that we don't need to take responsibility for our actions.
Murderers and rapists are suddenly off the hook. What kind of a crappy theory is this? Philosophers have long sought to pull apart the issue.
Is Free Will an Illusion?
Unfortunately, even the deepest thinkers among the human race have discovered it isn't nearly as clear cut as it seems. Many modern scientists and philosophers believe the universe is deterministic. Due to predictable laws of cause and effect, all future events are already logically determined by previous events. In other words, the starting conditions of the Big Bang have already determined the entire future of the universe, down to the movement of every last hydrogen atom.
Every single outcome in your life is inevitable. There is no room for your ego or your sense of free will to change things up.

This theory also says that, theoretically, mathematics could be used to predict everything in the future. In the land of science fiction, Isaac Asimov depicted this actually happening in his Foundation universe. In the spirit of destroying this argument, you might decide to make all your life choices based on a coin toss. Heads I stay, tails I go. Surely this is random. And by acting on it, you'll send ripples of non-determined change through the universe.
Give a computer the exact initial conditions regarding air flow, distance from the floor, position of the landing surface, impulse exerted on the coin, and so on. It will be able to predict the outcome of the toss. Even truly random events, such as the radioactive decay of an atom, do not create a free will loophole in determinism since there is no conscious influence present. Quantum mechanics defines probabilities to predict the behavior of particles, rather than determine the future with certainty. But we mustn't forget that the human brain is composed of such particles - and their behavior is governed by the laws of nature.
Though we may as yet be unable to predict the future of our universe with determinism, this natural principle holds true. There's metaphysical libertarianism, which is the polar opposite of determinism. It states: the fact that we are physically able to choose different outcomes denies determinism. For me, this like saying that because I have a knife and my partner's pissing me off today, then I am capable of choosing to murder him.
But that's not in my pathology.
Nor have I had any life experiences that incent me towards murder. There's no desire, no will. But libertarianism says there is - simply because I have a knife. Sub-branches of this philosophy, known as non-physical theories, say we have a metaphysical mind or soul which overrides causality. It makes way for the core beliefs of most of the world's religions, such as the Christian God giving man free will, or the still widespread belief that we have eternal souls.
The philosopher David Hume favored this middle ground, which claims to make determinism and free will compatible. The theory states that humans, animals and even computers make complex decisions in a determined world. And this creates a good enough representation of free will. Computers with free will? Just how crazy is this Hume fellow?

Compatibilists say that some deterministic processes are so chaotic that their outcomes that can't be predicted, even in principle. So will some things are determined, others simply aren't. A compatibilist can say "I may die on June 4th, Or I may not. Critics say this meddles with the definition of free will.
There is a difference between having the freedom to act versus having the conscious volition that can change a pre-determined course of events. Immanuel Kant firmly disliked it - calling it a "wretched subterfuge" and "word jugglery". Neuroscience gives us the opportunity to study the brain's biological processes that surround free will. Performing this voluntary action involves a lot of brain processes. To flex your wrist, activity begins in the prefrontal region, sending connections to the premotor cortex, which programs the desired action in the primary motor cortex.

Instructions are sent out to move the wrist muscles and the flex occurs. Scientists can identify which neurons are responsible for making this entire action happen from start to finish.
And guess what? The conscious part comes after the unconscious part. Meet Benjamin Libet. In , Benjamin Libet decided to test whether a wrist flex is originated by a conscious act of free will. He asked volunteers to perform the wrist flex action whenever they wanted, while measuring three events:. Naturally, you'd expect the sequence of events to occur A, B, C. Free will. Motor neurons fire. Wrist moves.
The automatic brain activity fired first B , then came the "decision" to act A , then came the wrist flex C. The timing separating these events was significant:. In other words, unconscious brain processes began planning the wrist flex movement more than half a second before the subject made any conscious decision. The results of Libet's experiment are controversial. They suggests conscious free will as trick of the mind. And yet, it makes perfect sense.
The idea of a conscious decision arising before any kind of brain activity would be nothing short of magic. In fact, if the free will decision had arisen first, this would be evidence for a metaphysical mind or soul. Either way, this experiment was always going to start some arguments. Libet did not conclusively say that free will is an illusion. Because during the course of the experiment, he noticed something peculiar occurring.
Some subjects said they aborted the conscious decision to flex their wrist at the last moment. In these cases, the motor cortex activity fired but then flattened out again at milliseconds. This implies the existence of a conscious veto : the ability to consciously override impulsive or automatic actions if we choose.
Libet's conclusion was that consciousness can't create the wrist flex action, but it can act to prevent it. It's not free will. It's free won't. Ethically, Libet is a hero. His experiment provides evidence for the condemning of criminals - who apparently failed to consciously veto their destructive impulses.
Unfortunately, there are criticisms of Libet's experiment. For instance, some doubt that we can generalize the results of trivial decision making to criminal behavior.
How strong is this conscious veto anyway? Yes, that is ironic. Because if you claim to consciously accept free will, you're also saying you could consciously deny it.

Which is a paradox. Because you can't consciously deny the fact that you can't consciously deny things. Making life choices - like choosing your career or selecting a partner - arguably feel like expressions of your own desires, based on your experiences, your personality and your individual choices. This is how you live your life. But what if all of these decisions are based on deterministic needs? What if your conscious justifications are always an afterthought? Is it possible that all your choices are pre-programmed responses?
That any sense of control over your life is merely an illusion created by consciousness? Passive Frame Theory says so. So what do you make of this revelation? Today, we know that the universe is chaotic. From such a view, one can be tempted to interject that if free will does not exist, why do we punish criminals? It is not their fault, after all. A counter-argument to that is that punishment is the natural response to crime, such that global equilibrium can be sustained, and therefore punishment is just as unavoidable as the commission of wrongdoing.
