Kitsch originated as a German term in the sentimental 19th century and has since permeated many Western languages. Over time, its original deeper meaning has faded, leading to a common understanding rooted in superficiality. It embodies a rejection of unpleasant aspects of life, purposefully avoiding topics or themes that may evoke discomfort or negativity.

This denial of the harsh realities of existence reflects a desire to present an idealized version of life, where only the acceptable and pleasing are acknowledged. Kundera suggests that kitsch ultimately limits our understanding by filtering out the complexity and depth of human experience, as it simplifies life into gratifying elements and disregards the essential struggles intrinsic to our nature.
