Polish literature is the literary tradition of Poland.
 Most Polish literature has been written in the Polish language, though other languages used in Poland over the centuries have also contributed to Polish literary traditions, including Latin, Yiddish, Lithuanian, Ukrainian, Belarusian, German and Esperanto.
 According to Czesław Miłosz, for centuries Polish literature focused more on drama and poetic self-expression than on fiction (dominant in the English speaking world).
 The reasons were manifold, but mostly rested on historical circumstances of the nation.
 Polish writers typically have had a more profound range of choices to motivate them to write, including historical cataclysms of extraordinary violence that swept Poland (as the crossroads of Europe); but also, Poland's own collective incongruities demanding adequate reaction from the writing communities of any given period.
The Captive Mind (Polish: Zniewolony umysł ) is a 1953 work of nonfiction by Polish writer, academic and Nobel laureate Czesław Miłosz, published in the English translation originally by Secker and Warburg.
 The work was written in Polish soon after the author received political asylum in Paris following his break with Poland's Communist government.
 It draws upon his experiences as an underground writer during World War II, and his position within the political and cultural elite of Poland in the immediate post-war years.
 The book attempts to explain both the intellectual allure of Stalinism and the temptation of collaboration with the Stalinist regime among intellectuals in post-war Central and Eastern Europe.
 Miłosz describes the book as having been written "under great inner conflict".
