Habitus is ingrained habits, skills and dispositions. It is the way that individuals perceive the social world around them and react to it. These dispositions are usually shared by people with similar backgrounds (such as social class, religion, nationality, ethnicity, education and profession). The habitus is acquired through imitation (mimesis) and is the reality that individuals are socialized, which includes their individual experience and opportunities. Thus, the habitus represents the way group culture and personal history shape the body and the mind; as a result, it shapes present social actions of an individual.
French sociologist Pierre Bourdieu suggested that the habitus consists of both the hexis (the tendency to hold and use one's body in a certain way, such as posture and accent) and more abstract mental habits, schemes of perception, classification, appreciation, feeling, as well as action. These schemes are not mere habits: Bourdieu suggested they allow individuals to find new solutions to new situations without calculated deliberation, based on their gut feelings and intuitions, which he believed were collective and socially shaped. These attitudes, mannerisms, tastes, moral intuitions and habits have influence on the individual's life chances, so the habitus not only is structured by an individual's objective past position in the social structure but also structures the individual's future life path. Bourdieu argued that the reproduction of the social structure results from the habitus of individuals.
The notion of habitus is extremely influential (with 400,000 Google Scholar publications using it), yet it also evoked criticism for its alleged determinism, as Bourdieu compared social actors to automata (while relying on Leibniz's theory of Monads).
The concept of habitus has been used as early as Aristotle but in contemporary usage was introduced by Marcel Mauss and later Maurice Merleau-Ponty. However, it was Pierre Bourdieu who turned it into a cornerstone of his sociology, and used it to address the sociological problem of agency and structure: the habitus is shaped by structural position and generates action, thus when people act and demonstrate agency they simultaneously reflect and reproduce social structure. Bourdieu elaborated his theory of the habitus while borrowing ideas on cognitive and generative schemes from Noam Chomsky and Jean Piaget dependency on history and human memory. For instance, a certain behaviour or belief becomes part of a society's structure when the original purpose of that behaviour or belief can no longer be recalled and becomes socialized into individuals of that culture.
Loïc Wacquant wrote that habitus is an old philosophical notion, originating in the thought of Aristotle, whose notion of hexis ("state") was translated into habitus by the Medieval Scholastics. Bourdieu first adapted the term in his 1967 postface to Erwin Panofsky's Gothic Architecture and Scholasticism. The term was earlier used in sociology by Norbert Elias in The Civilizing Process (1939) and in Marcel Mauss's account of "body techniques" (techniques du corps). The concept is also present in the work of Max Weber, Gilles Deleuze, and Edmund Husserl.
Mauss defined habitus as those aspects of culture that are anchored in the body or daily practices of individuals, groups, societies, and nations. It includes the totality of learned habits, bodily skills, styles, tastes, and other non-discursive knowledges that might be said to "go without saying" for a specific group (Bourdieu 1990:66-67)--in that way it can be said to operate beneath the level of rational ideology.
According to Bourdieu, habitus is composed of:
[s]ystems of durable, transposable dispositions, structured structures predisposed to function as structuring structures, that is, as principles which generate and organize practices and representations that can be objectively adapted to their outcomes without presupposing a conscious aiming at ends or an express mastery of the operations necessary in order to attain them.
The term has also been adopted in literary criticism, adapting from Bourdieu's usage of the term. For example, Joe Moran's examination of authorial identities in Star Authors: Literary Celebrity in America uses the term in discussion of how authors develop a habitus formed around their own celebrity and status as authors, which manifests in their writing.
Bourdieu's principle of habitus is interwoven with the concept of structuralism in literary theory. Peter Barry explains, "in the structuralist approach to literature there is a constant movement away from interpretation of the individual literary work and a parallel drive towards understanding the larger structures which contain them" (2009, p. 39). There is therefore a strong desire to understand the larger influencing factors which makes an individual literary work. As Bourdieu explains, habitus "are structured structures, generative principles of distinct and distinctive practices - what the worker eats, and especially the way he eats it, the sport he practices and the way he practices it, his political opinions and the way he expresses them are systematically different from the industrial proprietor's corresponding activities / habitus are also structuring structures, different classifying schemes classification principles, different principles of vision and division, different tastes. Habitus make different differences; they implement distinctions between what is good and what is bad, what is right and what is wrong, between what is distinguished and what is vulgar, and so on, but they are not the same. Thus, for instance, the same behaviour or even the same good can appear distinguished to one person, pretentious to someone else, and cheap or showy to yet another" (Bourdieu, 1996). As a result, habitus may be employed in literary theory in order to understand those larger, external structures which influence individual theories and works of literature.
Body habitus (or "bodily habitus") is the medical term for physique, and is categorized as either endomorphic (relatively short and stout), ectomorphic (relatively long and thin) or mesomorphic (average dimensions). In this sense, habitus has in the past been interpreted as the physical and constitutional characteristics of an individual, especially as related to the tendency to develop a certain disease. For example, "Marfanoid bodily habitus".
