Postmodernism is a complex concept that emerged as an area of academic study in the mid-1980s and spans multiple disciplines, including art, literature, and sociology. It shares similarities with modernism, such as the rejection of rigid boundaries between high and low art, but differs in its attitude towards fragmentation and incoherence, embracing them rather than lamenting them. Additionally, postmodernism critiques 'grand narratives' of modernity, favoring localized 'mini-narratives' and exploring how knowledge is organized and perceived in contemporary society.
