Causal determinism is the concept that prior causes give rise to everything that exists such that reality could not be anything other than what it is. Science depends on this idea as it aims to find generalizations about the conjunction of certain causes and effects and therefore to have a certain power of prediction about their future concomitance. However, in human interaction people assume that each other is responsible for their acts and not simply at the whim of causal laws. So the question that worries philosophers is whether causality entirely dictates the course of human action or whether we as agents possess some free will. I will argue that free will is an inevitable illusion of the mind, something that has never existed and could never exist under causal determinism. Compatibilists propose that free will and determinism coexist while for incompatibilists this would be impossible. If we are to decide for ourselves, we must first establish the meaning of causal determinism and freedom of the will. Proponents of causal determinism argue that1. Every event has a cause2. Human actions constitute a sort of event3. Therefore every human action has a cause4. Every action ever performed is nothing more than an inevitable consequence of previous conditions in the universe. Thus, if causal determinism is true, human beings have no ability to choose or will since nothing could ever be different from what it is. (McFee. 2000, p. 21) Free will is a much more elusive concept. However, the authors seem to agree on some aspects. In his article Has the Self “Free Will”? Campbell suggests that effective free will is confined to the domain of moral decisions. It states that to exercise free will an agent must be the sole author of an act, and not simply yield… middle of paper… an elusive illusion of the mind. In the same way that Strawson argues that the truth of determinism would not make agents less morally responsible, I believe that the falsity of free will does not detract from its usefulness in clarifying our mental narratives and explaining the origins of our actions.
