Aristotle's concept of disposition (hexis) is central to his ethics and psychology. A hexis is a stable, acquired character trait — it is what results from the habituation that constitutes moral education. Virtues are dispositions (the disposition to feel the appropriate emotion in the appropriate degree in the appropriate circumstances), and they are developed through practice. In contemporary philosophy of mind, dispositionalism treats mental states as dispositions — to believe something is to be disposed to act in certain ways, not to hold a mental
image. Ryle's concept of the "
ghost in the machine" critiques Cartesian dualism partly by arguing that mental concepts refer to dispositions rather than occurrent mental events. For poets, disposition is relevant to the question of character in narrative poetry and to the phenomenological question of how pre-reflective orientations toward the world shape what we perceive. Related terms: hexis, virtue, habituation, Ryle's dispositional analysis, character, Bourdieu's habitus.
