Free will or determinism?

The early 19th century’s Galvanism claims that humans are no more than machines, were the first to oppose widely held beliefts of the importance of the soul. Psychologists have since picked up the scientists-Romantics argument, and has presented some interesting claims…

Determinism:

  • Biological determinism, which comes from behaviour built into genes which persist into the genome due to evolutionary fitness – high IQ has been related to the IGF2R gene (Chorney et al 1998). This can also contribute to variation in brain structures – schizophrenic patients have been found to have ventricular enlargement and hypofrontality (Gazer et al 2000, Molina et al 2005).
  • Bandura (1961) supports the idea of environmental determinism – children who watch violent models imitate their behaviour
  • All behavious is under stimulus control, according to behavioural psychologists such as Skinner. He believed hat actions are goverened by certain universal scientific laws, so that each action is caused by a specific prior cause, and human action is no exception. Therefore all of behaviourism’s research supports determinism.
  • However, psychologists cannot fully predict behaviour 100% of the time due to the complex interaction of variables which can influence behaviour
  • The view of determinism is supported by the presence of mental illnesses: it is nobody’s choice to lose contact with reality or all sense of happiness in their everyday lives

Free will:

  • is the idea that we make our own choices all of the time, and is supported mainly by the Humanistic approach
  • This approach has had much criticism, including its lack of scientific rigour and use of bias-prone methods such as interviews
  • Cognitive psychologists are also inclined to attribute importance to free will as they only support a soft determinist view
  • The ethical argument also supports free will. In order to expect moral responsibility, one must accept the concept of free will. If an individual’s behaviour is determined by forces beyond an individual’s control then the individual cannot be held responsible for their actions. However our laws insist that adults do have individual responsibility for their actions and so implicitly society supports free will.

Overall? – the idea of determinism is a more accepted one today, with advancing neuroscientific research of high scientific rigour. While this side of the argument is more dominant, we cannot doubt that free will does play a significant, albeit minor, role in bheaviour which subtly underpins major decisions.

One thought on “Free will or determinism?

  1. A reasonable definition of free will is wholly consistent with a reasonable definition of determinism.

    Based upon our past experience, our beliefs, our desires, our values, our feelings, and our reasons, we choose. That choice becomes our will at that point in time. It is called “will” because it is the future we have chosen. If no one coerces us to do their will instead of our own, then we are free to follow our own will. That is what simple free will means. Nothing more. Nothing less.

    Determinism is simply the logical result of cause and effect. We observe that things happen due to specific, relevant causes, and that these causes each have their own causes. In theory, everything that happens is “inevitable”.

    What confuses people is that “inevitable” usually implies something “beyond our control”. But determinism must include ALL relevant causes. And our mental process of making choices is the relevant cause of a lot of what becomes inevitable. It could be as simple as having chocolate rather than vanilla, or it could be as significant as raising the temperature of the planet.

    If a man stands with a gun in his hand and chooses to shoot someone, we may say that his feelings and reasons caused him to make that choice. But none of those feelings and reasons were sufficient to pull the trigger on their own. It was only through his choosing and acting upon that choice that the gun was fired. Without that choice and that action, the gun would never have been fired. He, and he alone, made the shooting inevitable.

    When defined correctly, both determinism and free will are phenomena that are observed objectively, and simultaneously, in our real world.

    All other definitions may be dismissed.
