The question of whether or not people can choose their thoughts and actions has been a topic that many great thinkers throughout history have pondered . Yet despite countless arguments for and against, no one has been able to prove whether free will exists or not. Free will is the ability to make a choice not determined by external stimuli. The opposite of free will is determinism. Hard determinists argue that free will does not exist; people do not have the ability to choose freely, without being determined by external stimuli. Yet despite many compelling arguments for this cause, strict determinism fails to account for the unique quality of humanity. Humanity has the capacity to think and reason, which ultimately gives it the unique attribute of agent-causation. Hard determinism holds that all events have a cause. Hard determinists define human thoughts and actions as events. If human thoughts and actions are events, then they must be caused. If every human thought and action is caused, then humans do not have the ability to choose their own thoughts and actions because they are entirely dependent on prior causes. If this is the case, free will cannot exist. Hard determinists further argue that if there is no free will, then there can be no moral responsibility, because if a man or woman cannot choose to do anything other than what they have done , no responsibility can fall on them for their thoughts or actions. Their actions were simply caused by something else, which was caused by something else, and so on. Although hard determinists provide a valid argument, it is ultimately false. Looking at their first argument, it is easy to see how much they believe the premise to be true. After all, anyone... middle of paper... the hot dog is gone, that still leaves a 1% chance of change, for another decision. This may be due to chance, but that does not mean that the decision made is random. In reality, this small random percentage gives him the choice to change his decision. In conclusion, free will is not only possible, but entirely probable, and, if it exists, there is of course a moral responsibility. Hard determinists have many valid arguments to make their case, but the best of them, the argument from random probability, cannot be proven. Human understanding of physics is simply not advanced enough to prove the truth of their claims. Perhaps at some point this will change, but for now it is not a sufficient argument to refute the possibility of free will, while the previously mentioned arguments in favor of free will find the concept of free will quite likely..
