What is the theme in To the Lighthouse by Virginia Woolf?

WW1 is a theme in this book. In To the Lighthouse, the Great War takes place during the "Time Passes" section. The structure of the novel reflects the impact of World War I on European society. Part One is set in the golden haze of prewar innocence and love. Mr. Ramsay entertains himself by reciting Lord Tennyson's poem The Charge of the Light Brigade, a poem about death during the Crimean War, which valorizes the heroism of the then-unprecedented loss of a cavalry unit.
