I ply agree with the contention that absence of choice is a rare circumstance, primarily because this contention accords with common sense and our everyday experience as human beings. Besides, the reverse claim-that we do not have free choice-serves to undermine the notions of moral accountability and human equality, which are critical to the survival of any democratic society.

41. The role of free will of humans in choice

Common sense dictates that humans have free will, and therefore the true absence of choice is very rare. The only possible exceptions would involve extreme and rare circumstances such as solitary imprisonment or a severe mental or physical deficiency—any of which might potentially strip a person of his or her ability to make conscious choices. Yet, even under these circumstances, a person still retains choices about voluntary bodily functions and movement. Thus, the complete absence of choice would seem to be possible only in a comatose state or in death.

42. The nature of absence of choice

People often claim that life’s circumstances leave them with "no choice." One might feel trapped in a job or a marriage. Under financial duress a person might claim that he or she has "no choice" but to declare bankruptcy, take a demeaning job, or even lie or steal to obtain money. The fundamental problem with these sorts of claims is that the claimants are only considering those choices that are not viable or attractive. That is, people in situations such as these have an infinite number of choices; it’s just that many of the choices are unappealing, even self-defeating.

43. Choice is beyond our control

Besides, the contention that we are almost invariably free to choose is far more appealing from a sociopolitical standpoint than the opposite claim. A complete tack of choice implies that every person’s fate is determined, and that we all lack free will. According to the philosophical school of "strict determinism," every event, including human actions and Choices, that occurs is physically necessary given the laws of nature and events that preceded that event or choice. In other words, the "choices" that seem part of the essence of our being are actually beyond our control.

44. The logical result of strict determinism and of the new "scientific determinism"

However, the logical result of strict determinism and of the new "scientific determinism" is that we are not morally accountable for our actions and choices, even those that harm other individuals or society. Moreover, throughout history monarchs and dictators have embraced determinism, at least ostensibly, to bolster their claim that certain individuals are preordained to assume positions of authority or to rise to the top levels of the socioeconomic infrastructure. Finally, the notion of scientific determinism opens the door for genetic engineering, which poses a potential threat to equality in socioeconomic opportunity, and could lead to the development of a so-called "master race." Admittedly, these disturbing implications neither prove nor disprove the determinists’ claims.

45. Insistence of tree will

I would concede that science might eventually disprove the very notion of free will. However, until that time I’ll trust my p intuition that free will is an essential part of our being as humans and, accordingly, that humans are responsible for their own choices and actions.

[A] For example, almost every person who claims to be trapped in a job is simply choosing to retain a certain measure of financial security. The choice to forego this security is always available, although it might carry unpleasant consequences.

[B] Our collective life experience is that we make choices and decisions every day on a continual basis.

[C] However, the dilemma seams to be unavoidable which gives people a lot of Painfully experience with it.

[D] In sum, despite the fact that we all experience occasional feelings of being trapped and having no choice, the statement is fundamentally correct.

[E] Recent advances in molecular biology and genetics lend some credence to the determinists’ position that as physical beings our actions are determined by physical forces beyond our control. New research suggests that these physical forces include our own individual genetic makeup.

[F] Assuming that neither free will nor determinism has been proven to be the correct position, the former is to be preferred by any humanist and in any democratic society.
