Free Will (9)

Philosophers, scientists, and theologians have long grappled with the concept of free will. Thomas Aquinas, a 13th century philosopher, believed that humans are pre-programmed to seek certain goals, but are able to choose the means to achieve them. Some interpretations of Aquinas' view align with compatibilism, the belief that free will is compatible with determinism, while others align with libertarianism, the belief that free will exists independently of determinism. Buddhism accepts both determinism and free will, but denies the Western concept of a separate agent outside of the self. Hinduism also has different views on free will, with some schools emphasizing determinism and others focusing on free will as a means to moral progress.

In terms of science, the question of determinism has been addressed by physics, while the study of decision-making and action initiation has been explored by neuroscientists. Some observations from these fields have been interpreted as evidence against the existence of free will, but others disagree with this conclusion. The nature versus nurture debate in biology also relates to free will, as does the study of brain activity in relation to voluntary action. Some have argued that the time scales involved in motor control make it too narrow a context for considering free will, and that it is a higher level activity that cannot be explained by neural activity or muscle activation. Others have questioned the accuracy and interpretation of experiments on the subject, and some have suggested that free will exists on a spectrum, influenced by both conscious and unconscious processes. Conditions such as Tourette syndrome, where individuals cannot fully control their actions, also shed light on the concept of free will.

The concept of free will has been examined by philosophers and scientists for centuries, with many attempting to define it in terms of the words "free", "freedom", "will", and "choice". While some philosophers argue that the concept is simply a verbal issue and therefore a pseudo-problem, others believe that the complexities of decision making and the importance of subtle nuances in language make it a significant topic. In Hindu philosophy, the six orthodox schools have different views on free will, with some, like the Samkhya and Yoga schools, seeing it as limited or non-existent. In Buddhism, the concept of free will is seen as conditioned and not truly "free", and is instead based on the concept of "dependent origination".

In terms of science, the question of whether nature is deterministic has been a central concern, with some areas, such as quantum mechanics, being indeterministic. Neuroscientific studies have also been conducted on decision making and the initiation of actions, with some suggesting that free will may not exist or is an illusion. Additionally, psychologists have studied the beliefs that most people hold about free will and moral responsibility. In terms of biology, the "nature versus nurture" debate has also touched on issues of free will, with some arguing that genetics and biology play a significant role in human behavior. Neurological conditions, such as Tourette syndrome and alien hand syndrome, and mental illnesses like schizophrenia, have also been used to examine the existence of free will.

According to Wegner, when people feel that they are consciously willing an action, they are inferring that their conscious thought caused the action to occur based on the fact that the conscious thought immediately precedes the action. However, Wegner argues that this inference is not necessarily correct, as there may be unconscious processes that also contribute to the action. Wegner's work has led to a great deal of discussion and debate among psychologists and philosophers. While some agree with Wegner's conclusion that the perception of conscious will is an illusion, others argue that there is still much that we do not understand about the relationship between conscious thought and action and that it is premature to conclude that conscious will is an illusion.

The field of science has contributed to the debate on free will in several ways. Firstly, physics has explored the question of whether the universe operates in a deterministic manner, which is seen as crucial by those who believe free will and determinism are incompatible. Secondly, neuroscientists have studied how people make decisions and initiate actions, which are crucial components of free will. Some observations made in these studies have led some people to conclude that free will does not exist or is an illusion, although others disagree with this interpretation. Finally, psychologists have examined the beliefs that most people hold about free will and its role in assigning moral responsibility.

Throughout history, the concept of free will has been a topic of much debate among scientists and philosophers. Some early theories held that the universe was entirely deterministic, meaning that future events could be predicted with perfect accuracy if sufficient information was available. However, modern science suggests that the universe is a mix of deterministic and stochastic (random) theories, with quantum mechanics predicting events only in terms of probabilities. This has led some to question whether free will even exists, as it is unclear whether our actions are determined by external factors or are influenced by our own mental processes.

Several studies have been conducted to examine the relationship between free will and brain activity. For example, Benjamin Libet's experiments in the 1980s found that unconscious brain activity called the readiness potential occurred approximately half a second before a person was aware of their intention to move. This has led some to believe that our sense of conscious will may be an illusion, as it appears that our brains initiate actions before we are aware of making a decision. However, these findings have been challenged by other researchers, and the relationship between brain activity and free will is still a subject of debate.

Other conditions, such as Tourette syndrome and alien hand syndrome, also suggest that our sense of control over our actions may be limited. In Tourette syndrome, individuals may experience involuntary movements and utterances (tics) that they feel are irresistible and must be expressed, even if they are socially inappropriate. Alien hand syndrome involves one limb behaving as if it has a will of its own, with the individual experiencing a lack of control over its actions. Similarly, people with schizophrenia may report feeling as if they are being controlled by an external force, despite acting in the world.
