A disposition is a quality of character, a habit, a preparation, a state of readiness, or a tendency to act in a specified way.
The terms dispositional belief and occurrent 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 Bourdieu'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.
