<human>:  Why did Jean-Francois Lyotard write the book ‘The Postmodern Condition’?
<bot>: Lyotard wrote The Postmodern Condition to explain what the postmodern condition is. He argued that the postmodern condition is characterized by the proliferation of different types of media and the decline of traditional institutions, such as the church, the state, and the family. Lyotard believed that this new condition had a negative impact on human life, and that it was therefore necessary to develop a new philosophy to deal with it.
