<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. Postmodernism is a philosophical movement that began in the 1960s. Postmodernists argue that modernism, a philosophy that was dominant in the 20th century, is finished. Postmodernists argue that the modernist belief that science and reason are the best way to understand the world is flawed. Postmodernists believe that we must accept that there are many different ways of knowing the world, and that we should be open to new ways of understanding the world.
