Concept
Will, within philosophy, is a faculty of the mind. Will is important as one of the parts of the mind, along with reason and understanding. It is considered central to the field of ethics because of its role in enabling deliberate action. A recurring question in Western philosophical tradition is about free willand the related, but more general notion of fatewhich asks how the will can truly be free if a person's actions have either natural or divine causes determining them. In turn, this is directly connected to discussions on the nature of freedom and to the problem of evil. The classical treatment of the ethical importance of will is to be found in the Nicomachean Ethics of Aristotle, in Books III (chapters 1–5), and Book VII (chapters 1–10). These discussions have been a major influence in the development of ethical and legal thinking in Western civilization. In Book III Aristotle divided actions into three categories instead of two: Voluntary (ekousion) acts. Involuntary or unwilling (akousion) acts, which are in the simplest case where people do not praise or blame. In such cases a person does not choose the wrong thing, for example if the wind carries a person off, or if a person has a wrong understanding of the particular facts of a situation. Note that ignorance of what aims are good and bad, such as people of bad character always have, is not something people typically excuse as ignorance in this sense. "Acting on account of ignorance seems different from acting while being ignorant". "Non-voluntary" or "non willing" actions (ouk ekousion) which are bad actions done by choice, or more generally (as in the case of animals and children when desire or spirit causes an action) whenever "the source of the moving of the parts that are instrumental in such actions is in oneself" and anything "up to oneself either to do or not". However, these actions are not taken because they are preferred in their own right, but rather because all options available are worse.
