The Spirit of Revolt (1880)
Context: One courageous act has sufficed to upset in a few days the entire governmental machinery, to make the colossus tremble; another revolt has stirred a whole province into turmoil, and the army, till now always so imposing, has retreated before a handful of peasants armed with sticks and stones. The people observe that the monster is not so terrible as they thought they begin dimly to perceive that a few energetic efforts will be sufficient to throw it down. Hope is born in their hearts, and let us remember that if exasperation often drives men to revolt, it is always hope, the hope of victory, which makes revolutions.
The government resists; it is savage in its repressions. But, though formerly persecution killed the energy of the oppressed, now, in periods of excitement, it produces the opposite result. It provokes new acts of revolt, individual and collective, it drives the rebels to heroism; and in rapid succession these acts spread, become general, develop. The revolutionary party is strengthened by elements which up to this time were hostile or indifferent to it.

this is a line spoken by Frank Morgan's depiction of the Wizard of Oz in the 1939 film, which debuted 20 years after Baum's death. It did not actually appear in the "Wonderful Wizard of Oz". The ending of "Steam Engines of Oz" wrongly attributes this phrase to Baum when it would've originated from the 1939 adaptation script writers Langley/Ryerson/Woolf.
