The History of Freedom in Antiquity (1877)
Context: Before God, there is neither Greek nor barbarian, neither rich nor poor; and the slave is as good as his master, for by birth all men are free; they are citizens of that universal commonwealth which embraces all the world, brethren of one family, and children of God.

Ch 10
The Little Lame Prince and his Travelling Cloak (1875)
Context: Thus King Dolor's reign passed, year after year, long and prosperous. Whether he was happy — "as happy as a king" — is a question no human being can decide. But I think he was, because he had the power of making everybody about him happy, and did it too; also because he was his godmother's godson, and could shut himself up with her whenever he liked, in that quiet little room in view of the Beautiful Mountains, which nobody else ever saw or cared to see. They were too far off, and the city lay so low. But there they were, all the time. No change ever came to them; and I think, at any day throughout his long reign, the King would sooner have lost his crown than have lost sight of the Beautiful Mountains.
