“There is a breed of men who do not deserve the name of Germans. I trust that the entire nation will find the strength to beat back their outrageous attacks. If that does not occur, I shall have to call on you, my Guards, for protection against the gang of traitors and for leading the battle which will free us from such elements.”

Short fiction, The Spawn Of Dagon (1938)
Context: "They dare'd not invade the palace while the globe shone, for the light-rays would have killed them. … This island-continent would have gone down beneath the sea long ago if I hadn't pitted my magic and my science against that of the children of Dagon. They are masters of the earthquake, and Atlantis rests on none too solid a foundation. Their power is sufficient to sink Atlantis forever beneath the sea. But within that room" — Zend nodded toward the curtain that hid the sea-bred horrors — "in that room there is power far stronger than theirs. I have drawn strength from the stars, and the cosmic sources beyond the universe. You know nothing of my power. It is enough — more than enough — to keep Atlantis steady on its foundation, impregnable against the attacks of Dagon's breed. They have destroyed other lands before Atlantis."

Et scahiez que Anglois et Escoçoiz, quant ilz se treuvent en bataille ensamble, sont dures gens et de longue alainne, et point ne s'esparngnent, mais s'entendent de eulx mettre à oultranche, comment qu'il prende. Ilz ne ressamblent pas les Alemans qui font une empainte, et, quant ilz voient qu'ilz ne puellent rompre ne entrer en leurs ennemis, ilz s'en retournent tout à ung fais.

Douglass here quotes William Lloyd Garrison, who famously declared in the first issue of The Liberator: "I am in earnest — I will not equivocate — I will not excuse — I will not retreat a single inch — AND I WILL BE HEARD."
1850s, What to the Slave is the Fourth of July? (1852)
Context: I shall see, this day, and its popular characteristics, from the slave's point of view. Standing, there, identified with the American bondman, making his wrongs mine, I do not hesitate to declare, with all my soul, that the character and conduct of this nation never looked blacker to me than on this 4th of July! Whether we turn to the declarations of the past, or to the professions of the present, the conduct of the nation seems equally hideous and revolting. America is false to the past, false to the present, and solemnly binds herself to be false to the future. Standing with God and the crushed and bleeding slave on this occasion, I will, in the name of humanity which is outraged, in the name of liberty which is fettered, in the name of the constitution and the Bible, which are disregarded and trampled upon, dare to call in question and to denounce, with all the emphasis I can command, everything that serves to perpetuate slavery — the great sin and shame of America! "I will not equivocate; I will not excuse;" I will use the severest language I can command; and yet not one word shall escape me that any man, whose judgement is not blinded by prejudice, or who is not at heart a slaveholder, shall not confess to be right and just.
