Allow me to give an example of a complex situation in which it would be entirely inappropriate to state that someone's behavior was the product of what might be called "free will."
Frederick William was the King of Prussia from 1713 to 1740. He was the father of Frederick, who became King Frederick II, famous as Frederick the Great. Frederick William suffered from a condition known as porphyria--in his case he suffered from acute porphyria, and there was no treatment for the condition in the 18th century (it cannot be cured, and only managed with the medical knowledge we possess today). He lived most of his adult life in severe pain, and was given to fits of temper in which he verbally and even physically abused those around, from mere employees of the royal administration to his principle ministers and the members of his family. On one occassion, when Frederick was still a boy, his father became angry at a remark he made at the dinner table, and beat him into insensibility, lashing out at his wife and daughter when they attempted to intervene, so that they fled the room in tears and hysterical.
From the
National Digestive Disease Information Clearinghouse page on porphyria:
Quote:personality changes or mental disorders. These symptoms appear intermittently. (emphasis was added, and original emphases have been removed)
Therefore, i one were to ask, as MOAN did above, whether or not Frederick William made the decision to beat his son into insensibility, or whether someone else made the decision for him--the answer in both cases would be no. Frederick William suffered a physical condition which lead him to behave in an irrational manner for which it would not be reasonble to consider him to have been responsible--his wild fits of violent temper were not the product of the exercise of "free will."
This is simply one example of how it is that a person's behavior may not be the product of a conscious effort of will on the part of that person. I chose that example because it is extreme and dramatic. Nevertheless, it is an example out of many thousand examples of conditions and circumstances in which a person might act, while making no conscious effort of will to act in any particular manner, and many in which a person may behave compulsively contrary to their personal desires.
