A disposition is an artificial habit, a preparation, a state of readiness, or a tendency to act in a specified way. It may be learned. The terms "dispositional belief" in the current belief refer, in the former case, to a belief that is held in the mind but not currently being considered, and in the latter case, to a belief that is currently being considered by the mind. In Purdue's theory of fields, dispositions are the natural tendencies of each individual to take on a specific position in any field. There is no strict determinism through one's dispositions. The habitus is the choice of positions according to one's dispositions. However, in retrospect, a space of possibilities can always be observed. A disposition is not a process or event in some duration in time, but rather the state, preparation, or tendency of a structure in waiting in the field of possibilities. Its actual triggering has a statistical value. In contemporary analytic philosophy, dispositions have been suggested as having an important role in understanding laws of nature. Dispositionalism is the idea that the dispositions of objects, for instance, the disposition for a wineglass to break if dropped on the hard floor, are a specific and ontologically important set of properties, either universals or tropes, that objects have. Philosophers who subscribe to this theory include Sidney Shoemaker, Stephen Mumford, Alexander Byrd, George Molnar, Brian Ellis, CB Martin, and John Hale. Dispositionalism is offered as an alternative to other accounts of laws of nature, including neo-Humean regularity theories and relations between universals theory of David Mele Armstrong, Fred Rest, and Michael J. Loux. In a disposition, a civil or criminal hearing where a case can be resolved.
