Eclecticism is a kind of mixed style in the fine arts, in which features are borrowed from various sources and styles. Significantly, Eclecticism hardly ever constituted a specific style in art: it is characterized by the fact that it was not a particular style. In general, the term describes the combination in a single work of a variety of influences - mainly of elements from different historical styles in architecture, painting, and the graphic and decorative arts. In music the term used may be either eclecticism or Crossover music.
In the 18th century, Sir Joshua Reynolds, head of the Royal Academy of Arts in London, was one of the most influential advocates of eclecticism. In the sixth of his famous academical Discourses (1774), he wrote that the painter may use the work of the ancients as a "magazine of common property, always open to the public, whence every man has a right to take what materials he pleases." In nineteenth-centuryEngland, John Ruskin also pleaded for eclecticism.
Eclecticism was an important concept in Western architecture during the mid- and late 19th century, and it reappeared in a new guise in the latter part of the 20th century.
Eclecticism is an approach to thought that does not hold rigidly to a single paradigm or set of assumptions or conclusions, but instead draws upon multiple theories to gain complementary insights into phenomena, or applies only certain theories in particular cases.
Eclecticism is a term that plays an important role in critical discussions and evaluations but is somehow distant from the actual forms of the artefacts to which it is applied, and its meaning is thus rather indistinct.
Eclecticism in psychology is also supported by many in that in reality many factors influence behaviour and psyche, therefore it is inevitable to consider all perspectives in identifying, changing, explaining, and determining behaviour.
