Postmodernism is the school of thought that is based on reactionary ideas, ideologies and movements. It is usually manifested as a form of rebellion and condemnation of established and dominant social structures that pervade contemporary society. Like existentialists and progressivists, postmodernists care very little about the expectations and ideals of society.

Examples of postmodernism in history include Martin Heidegger’s concept of existentialist phenomenology. He believed that truth was created within an individual rather than by an already existing environment. 

Another example is the deconstruction method which was created by Jacques Derrida. Deconstruction involves the breaking down and careful criticism of literary texts, political theories and philosophical texts. It aims to separate the valuable from the trivial in order to find deeper shades of meaning within history and society. 

Postmodernist education believes that there are no absolute truths and that truth is determined by individuals and events. Interactions between peoples and cultures have led to the creation of generally accepted truths, and reduced the individual expression that helped society thrive in the first place. As a result, postmodernist education values and encourages individual expression.

Postmodernist education emphasizes the creation of a holistic system of education that educates students on political, social, and economic structures that are present in current society and the cause of progress and problems in society.
