The concept of free will states that when more than one alternative is available to an individual, he/she chooses freely and voluntarily to render an action in any given context. A question arises, how do human beings choose to perform an action in a given context? What happens to an individual who compels him/her to choose an action out of many alternatives? The behaviorists state that free will guides individuals to choose an action voluntarily. Therefore, he/she is morally responsible for (...) his/her voluntary actions. This paper attempts to answer whether a person’s action is an outcome of his/her ‘moral luck’ or ‘designated cerebral cortex processes’? While answering this question the paper examines the relation between principle of causality and free will of a person. It analyses what causes free will. It elucidates use of free will for decision-making process(es), and the relation between human beings’ actions and their moral responsibility. This paper concludes that human beings are conscious of their free will. Free will decides their actions; therefore, they are morally responsible for their voluntary actions. This paper argues that free will is an emergent property of ‘immaterial soul’. (shrink)
