Practice theory refers to a theoretical approach to social phenomena which sought to resolve the antinomy between traditional structuralist approaches and approaches such as methodological individualism which attempted to explain all social phenomena in terms of individual actions. Practice theory is strongly associated with the French theorist and sociologist Pierre Bourdieu. His concept of habitus represents an important formulation of the principles of practice theory. His book, 'Outline of a Theory of Practice', which is based on his work in Algeria during the Algerian War of Independence is an example of Bourdieu's formulation of practice theory applied to empirical data gathered through ethnography. Methodological individualism is a widely-used term in the social sciences. Its advocates see it as a philosophical method aimed at explaining and understanding broad society-wide developments as the aggregation of decisions by individuals.
