Die Sonne scheint noch.
These were her last words as depicted in the film, Sophie Scholl - The Final Days (2005) http://www.sophieschollmovie.com/, which was heavily based on Gestapo documents that were in East German archives and not released until 1990. Her last words have also been reported as "God, you are my refuge into eternity" or sometimes "Your heads will fall as well" but there is dispute over whether Sophie or her brother Hans had said this. Hans' last words have been reported as having been Es lebe die Freiheit! ["Long Live Freedom!"]

On Literature, Revolution, Entropy and Other Matters (1923)
Context: When the flaming, seething sphere (in science, religion, social life, art) cools, the fiery magma becomes coated with dogma—a rigid, ossified, motionless crust. Dogmatization in science, religion, social life, or art is the entropy of thought. What has become dogma no longer burns; it only gives off warmth — it is tepid, it is cool. Instead of the Sermon on the Mount, under the scorching sun, to up-raised arms and sobbing people, there is drowsy prayer in a magnificent abbey. Instead of Galileo's "But still, it turns!" there are dispassionate computations in a well-heated room in an observatory. On the Galileos, the epigones build their own structures, slowly, bit by bit, like corals. This is the path of evolution — until a new heresy explodes the crush of dogma and all the edifices of the most enduring stone which have been raised upon it.
Explosions are not very comfortable. And therefore the exploders, the heretics, are justly exterminated by fire, by axes, by words. To every today, to every evolution, to the laborious, slow, useful, most useful, creative, coral-building work, heretics are a threat. Stupidly, recklessly, they burst into today from tomorrow; they are romantics.

Section 8 : Suffering and Consolation
Founding Address (1876), Life and Destiny (1913)
Context: When the light of the sun shines through a prism it is broken into beautiful colours, and when the prism is shattered, still the light remains. So does the life of life shine resplendent in the forms of our friends, and so, when their forms are broken, still their life remains; and in that life we are united with them; for the life of their life is also our life, and we are one with them by ties indissoluble.
