"The broad masses of the people can be moved only by the power of speech. All great movements are popular movements, volcanic eruptions of human passions and emotional sentiments, stirred either by the cruel Goddess of Distress or by the firebrand of the word hurled among the masses; they are not the lemonade-like outpourings of the literary aesthetes and drawing-room heroes."
Wrote Adolf Hitler, quoted in "The Rise and Fall of the Third Reich."
I was listening to that in audiobook form during our long car ride yesterday. That passage struck me, and I made a point of remembering a word — "volcanic" — so I could search for it when I got home. I thought it related in interesting ways to present-day issues about speech.
