Scholars most commonly hold "postmodernism" to be a movement of ideas arising from, but also critical of elements of modernism. The wide range of uses of this term resulted in different elements of modernity are chosen as being continuous. Each of the different uses is rooted in some argument about the nature of knowledge, known in philosophy as epistemology. Individuals who use the term are arguing that either there is something fundamentally different about the transmission of meaning, or that modernism has fundamental flaws in its system of knowledge.
