Postmodernism succeeded the modernist philosophy that assumes rationality and universal truth, and application scientific empirical methods to problem solving (Engholm, 2001). Postmodernism, which came into use during the late 20th century, questions the notion of ìobjective truthî espoused by previous empiricist and realist approaches. This philosophy emphasises ìcontextual construction of meaning and the validity of multiple perspectives; knowledge is constructed by people and groups of people; reality is multiperspectival; truth is grounded in everyday life and social relations; life is a text but thinking is an interpretive act; facts and values are inseparable; and science and all other human activities are value-laden
