The Great War and Modern Memory: The Great War and Modern Memory is a book of literary criticism written by Paul Fussell and published in 1975 by Oxford University Press.

The perceived futility and insanity of this conduct became, for many gifted Englishmen of their generation, a metaphor for life.  Fussell describes how the collective experience of the "Great War" was correlated with, and to some extent underlain by, an enduring shift in the aesthetic perceptions of individuals, from the tropes of Romanticism that had guided young adults before the war, to the harsher themes that came to be dominant during the war and after.
