The problem of free will goes back to the Greek philosophers, 2000 years ago. The basic question that was always asked was whether we are free to make our actions and decisions. There are two major problems here. The first problem is determinism: if this universe runs through deterministic laws, then everything that happens should be inevitable. If this were true, there could be no free will. The second problem is moral responsibility: if I am not free to choose my actions, how can I feel morally responsible for these actions?Compatibilists believe that some things can be certain, but free will can still exist. There is a connection between the self and consciousness. We act as if there is an 'I' that makes conscious choices. It seems that our conscious thoughts are the cause of our actions. James rejected the idea of ​​a permanent self, but believed in a spiritual power. In his view, the feeling of effort is no illusion, but the cause of consciousness and of personal will. We know that thoughts and emotions play a role in decision-making. We weigh things up and compare them with each other. The question is where consciousness plays a role in this process. When we perform a voluntary action, the frontal lobes are activated. The prefrontal lobes activate motor actions. These send signals again to the premotoric areas that program the actions. This is again forwarded to the primary motor cortex to achieve motor output. The supplementary motor area is involved in the ordering and programming of motor actions according to a motor plan. The anterior cingulate selects the information needed for actions, pain and emotion.Damage to the dorsolateral prefrontal cortex (DLPFC) can lead to a lack of spontaneous activity and to stereotypic actions. Damage to the prefrontal area and the corpus callosum can result in an 'alien hand'. Patients who have an 'alien hand...
