Contextualism, a trend in thinking in the later parts of 20th century, influences the ideologies of the postmodern movement in general. Contextualism is centered on the belief that all knowledge is "context-sensitive". This idea was even taken further to say that knowledge cannot be understood without considering its context. While noteworthy examples of modern architecture responded both subtly and directly to their physical context, postmodern architecture often addressed the context in terms of the materials, forms and details of the buildings around it—the cultural context.
