Saul McLeod , published The determinist approach proposes that all behavior is caused by preceding factors and is thus predictable. The causal laws of determinism form the basis of science. Free will is the idea that we are able to have some choice in how we act and assumes that we are free to choose our behavior, in other words we are self determined. For example, people can make a free choice as to whether to commit a crime or not unless they are a child or they are insane.

This does not mean that behavior is random, but we are free from the causal influences of past events. According to freewill a person is responsible for their own actions. Some approaches in psychology see the source of determinism as being outside the individual, a position known as environmental determinism.

For example, Bandura showed that children with violent parents will in turn become violent parents through observation and imitation. Others see it from coming inside i. Behaviorists are strong believers in determinism.

Their most forthright and articulate spokesman has been B. For Skinner these causes lay in the environment — more specifically in physical and psychological reinforcers and punishments. S he is propelled in this direction by environmental circumstances and a personal history, which makes breaking the law natural and inevitable.

For the law-abiding, an accumulation of reinforcers has the opposite effect. Having been rewarded for following rules in the past the individual does so in the future. There is no moral evaluation or even mental calculation involved. All behavior is under stimulus control. The other main supporters of determinism are those who adopt a biological perspective.

However for them it is internal, not external, forces that are the determining factor. According to sociobiology evolution governs the behavior of a species and genetic inheritance that of each individual within it. For example Bowlby states a child has an innate i. Personality traits like extraversion or neuroticism, and the behavior associated with them, are triggered by neurological and hormonal processes within the body. There is no need for the concept of an autonomous human being.

Ultimately this view sees us as no more than biological machines and even consciousness itself is interpreted as a level of arousal in the nervous system. However, a problem with determinism is that it is inconsistent with society's ideas of responsibility and self control that form the basis of our moral and legal obligations.

One of the main assumptions of the humanistic approach is that humans have free will; not all behavior is determined. Personal agency is the humanistic term for the exercise of free will. Personal agency refers to the choices we make in life, the paths we go down and their consequences. For humanistic psychologists such as Maslow and Rogers freedom is not only possible but also necessary if we are to become fully functional human beings.

Both see self-actualisation as a unique human need and form of motivation setting us apart from all other species. There is thus a line to be drawn between the natural and the social sciences. To take a simple example, when two chemicals react there is no sense in imagining that they could behave in any other way than the way they do. However when two people come together they could agree, fall out, come to a compromise, start a fight and so on. The permutations are endless and in order to understand their behavior we would need to understand what each party to the relationship chooses to do.

Cognitive psychologists are also inclined to attribute importance to free will, and adopt a soft determinism view. Consequently, even a very small error in knowledge of initial conditions can result in arbitrarily large deviations from predicted behavior.

Chaos theory thus explains why it may be practically impossible to predict real life, whether determinism is true or false. On the other hand, the issue may not be so much about human abilities to predict or attain certainty as much as it is the nature of reality itself. For that, a closer, scientific look at nature is necessary. Quantum physics works differently in many ways from Newtonian physics.

O'Connell explains that understanding our universe, at such small scales as atoms, requires a different logic than day-to-day life does.

O'Connell does not deny that it is all interconnected: O'Connell argues that we must simply use different models and constructs when dealing with the quantum world.

The Heisenberg uncertainty principle is frequently confused with the observer effect. The uncertainty principle actually describes how precisely we may measure the position and momentum of a particle at the same time — if we increase the accuracy in measuring one quantity, we are forced to lose accuracy in measuring the other. This is where statistical mechanics come into play, and where physicists begin to require rather unintuitive mental models: A particle's path simply cannot be exactly specified in its full quantum description.

The probabilities discovered in quantum mechanics do nevertheless arise from measurement of the perceived path of the particle. As Stephen Hawking explains, the result is not traditional determinism, but rather determined probabilities. In fact, as far as prediction goes, the quantum development is at least as predictable as the classical motion, but the key is that it describes wave functions that cannot be easily expressed in ordinary language.

As far as the thesis of determinism is concerned, these probabilities, at least, are quite determined. These findings from quantum mechanics have found many applications , and allow us to build transistors and lasers. On the topic of predictable probabilities, the double-slit experiments are a popular example. Photons are fired one-by-one through a double-slit apparatus at a distant screen.

Curiously, they do not arrive at any single point, nor even the two points lined up with the slits the way you might expect of bullets fired by a fixed gun at a distant target.

Instead, the light arrives in varying concentrations at widely separated points, and the distribution of its collisions with the target can be calculated reliably. In that sense the behavior of light in this apparatus is deterministic, but there is no way to predict where in the resulting interference pattern any individual photon will make its contribution although, there may be ways to use weak measurement to acquire more information without violating the Uncertainty principle.

Some including Albert Einstein argue that our inability to predict any more than probabilities is simply due to ignorance. They argue that the course of the universe is absolutely determined, but that humans are screened from knowledge of the determinative factors. So, they say, it only appears that things proceed in a merely probabilistically determinative way.

In actuality, they proceed in an absolutely deterministic way. Bell criticized Einstein's work in his famous Bell's Theorem which proved that quantum mechanics can make statistical predictions which would be violated if local hidden variables really existed. There have been a number of experiments to verify such predictions, and so far they do not appear to be violated.

Better and better tests continue to verify the result, including the " Loophole Free Test " that plugged all known sources of error and the " Cosmic Bell Test " that based the experiment cosmic data streaming from different directions toward the Earth, precluding the possibility the sources of data could have had prior interactions. However, it is possible to augment quantum mechanics with non-local hidden variables to achieve a deterministic theory that is in agreement with experiment.

Bohm's Interpretation, though, violates special relativity and it is highly controversial whether or not it can be reconciled without giving up on determinism. More advanced variations on these arguments include Quantum contextuality , by Bell, Simon B.

Kochen and Ernst Specker in which argues that hidden variable theories cannot be "sensible," which here means that the values of the hidden variables inherently depend on the devices used to measure them.

This debate is relevant because it is easy to imagine specific situations in which the arrival of an electron at a screen at a certain point and time would trigger one event, whereas its arrival at another point would trigger an entirely different event e. Thus, quantum physics casts reasonable doubt on the traditional determinism of classical, Newtonian physics in so far as reality does not seem to be absolutely determined.

This was the subject of the famous Bohr—Einstein debates between Einstein and Niels Bohr and there is still no consensus. Adequate determinism see Varieties , above is the reason that Stephen Hawking calls Libertarian free will "just an illusion".

All uranium found on earth is thought to have been synthesized during a supernova explosion that occurred roughly 5 billion years ago. Even before the laws of quantum mechanics were developed to their present level, the radioactivity of such elements has posed a challenge to determinism due to its unpredictability. One gram of uranium , a commonly occurring radioactive substance, contains some 2.

Each of these atoms are identical and indistinguishable according to all tests known to modern science. Yet about times a second, one of the atoms in that gram will decay, giving off an alpha particle. The challenge for determinism is to explain why and when decay occurs, since it does not seem to depend on external stimulus.

Indeed, no extant theory of physics makes testable predictions of exactly when any given atom will decay. At best scientists can discover determined probabilities in the form of the element's half life.

That is, it explicitly and uniquely predicts the development of the wave function with time. So if the wave function itself is reality rather than probability of classical coordinates , then the unitary evolution of the wave function in quantum mechanics, can be said to be deterministic. But the unitary evolution of the wave function is not the entirety of quantum mechanics. Asserting that quantum mechanics is deterministic by treating the wave function itself as reality might be thought to imply a single wave function for the entire universe , starting at the origin of the universe.

Such a "wave function of everything" would carry the probabilities of not just the world we know, but every other possible world that could have evolved. For example, large voids in the distributions of galaxies are believed by many cosmologists to have originated in quantum fluctuations during the big bang. See cosmic inflation , primordial fluctuations and large-scale structure of the cosmos.

However, neither the posited reality nor the proven and extraordinary accuracy of the wave function and quantum mechanics at small scales can imply or reasonably suggest the existence of a single wave function for the entire universe. Quantum mechanics breaks down wherever gravity becomes significant, because nothing in the wave function, or in quantum mechanics, predicts anything at all about gravity. And this is obviously of great importance on larger scales. Gravity is thought of as a large-scale force, with a longer reach than any other.

But gravity becomes significant even at masses that are tiny compared to the mass of the universe. A wave function the size of the universe might successfully model a universe with no gravity. Our universe, with gravity, is vastly different from that which is predicted by quantum mechanics alone. To forget this is a colossal error. Objective collapse theories , which involve a dynamic and non-deterministic collapse of the wave function e.

Ghirardi—Rimini—Weber theory , Penrose interpretation , or causal fermion system s avoid these absurdities. The theory of causal fermion systems for example, is able to unify quantum mechanics , general relativity and quantum field theory , via a more fundamental theory which is non-linear, but gives rise to the linear behaviour of the wave function and also gives rise to the non-linear, non-deterministic, wave-function collapse.

These theories suggest that a deeper understanding of the theory underlying quantum mechanics shows the universe is indeed non-deterministic at a fundamental level.

A weaker version holds that, though not predestined to happen, everything that happens has been eternally known by virtue of the divine foreknowledge of an omniscient divinity.

If this divinity is also omnipotent, as in the case of the Judeo-Christian religions, this weaker version is hard to distinguish from the previous one because, though able to prevent what happens and knowing that it is going to happen, God lets it happen.

To this, advocates of free will reply that God permits it to happen in order to make room for the free will of humans. Encyclopedia of science and religion. Theological determinism constitutes a fifth kind of determinism.

There are two types of theological determinism, both compatible with scientific and metaphysical determinism. In the first, God determines everything that happens, either in one all-determining single act at the initial creation of the universe or through continuous divine interactions with the world. Either way, the consequence is that everything that happens becomes God's action, and determinism is closely linked to divine action and God's omnipotence.

According to the second type of theological determinism, God has perfect knowledge of everything in the universe because God is omniscient. And, as some say, because God is outside of time, God has the capacity of knowing past, present, and future in one instance. This means that God knows what will happen in the future.

And because God's omniscience is perfect, what God knows about the future will inevitably happen, which means, consequently, that the future is already fixed. VanArragon 21 October Key Terms in Philosophy of Religion.

Continuum International Publishing Group. Theological determinism, on the other hand, claims that all events are determined by God. On this view, God decree that everything will go thus-and-so and ensure that everything goes that way, so that ultimately God is the cause of everything that happens and everything that happens is part of God's plan.

We might think of God here as the all-powerful movie director who writes script and causes everything to go accord with it. We should note, as an aside, that there is some debate over what would be sufficient for theological determinism to be true. Some people claim that God's merely knowing what will happen determines that it will, while others believe that God must not only know but must also cause those events to occur in order for their occurrence to be determined.

The Stanford Encyclopedia of Philosophy Spring ed. We particularly agree that they are negligible when considering the causally determined will and the causally determined actions set in motion by decisions of that will. Instead it leads us to accept a new form of determinism: Given the state of a system at some time, the laws of nature determine the probabilities of various futures and pasts rather than determining the future and past with certainty. Therefore the soul stands to the activities of the individual agent's body as does the creator of the universe to the universe.

The creator of the universe put in motion a deterministic system of material entities that would, if left to themselves, carry out the chain of events determined by ordinary causation. But the creator also provided for souls that could exert a causal force analogous to the primordial causal force and alter outcomes in the physical universe via the acts of their bodies.

Thus, it emerges that no events in the physical universe are uncaused. Some are caused entirely by the original creative act and the way it plays itself out through time, and some are caused by the acts of created souls. But those created souls were not created by means of physical processes involving ordinary causation.

They are another order of being entirely, gifted with the power to modify the original creation. However, determinism is not necessarily limited to matter; it can encompass energy as well. The question of how these immaterial entities can act upon material entities is deeply involved in what is generally known as the mind-body problem.
