“Especially do the evils of the times, the folly and blindness of the masses, the injustice of rulers, the perversion of religion in unfruitful ceremonialism work upon the souls more finely attuned as a stimulus and spur; the feeling of the evil stirs their moral judgment or conscience to the criticism of the existing situation, and out of the criticism there grows for them the new ideal which impresses itself upon them as the truth that has the power to save from the corruption of the time; and while they first raise themselves to this ideal, they also win power and courage to draw others toward it. Thus they become the proclaimers of a higher truth which, over against the antecedent error, appears as something wholly new, as a revelation from above, but which is, indeed, nothing else than a higher development of the impulse toward truth and righteousness that is a natural quality of the human mind.”

Context: Don’t change the white man’s mind—you can’t change his mind, and that whole thing about appealing to the moral conscience of America—America’s conscience is bankrupt. She lost all conscience a long time ago. Uncle Sam has no conscience. They don’t know what morals are. They don’t try and eliminate an evil because it’s evil, or because it’s illegal, or because it’s immoral; they eliminate it only when it threatens their existence. So you’re wasting your time appealing to the moral conscience of a bankrupt man like Uncle Sam. If he had a conscience, he’d straighten this thing out with no more pressure being put upon him. So it is not necessary to change the white man’s mind.

Quotes:, Autobiography of Sir Henry Morton Stanley (1909)

Variant translation: I have never looked upon ease and happiness as ends in themselves — such an ethical basis I call more proper for a herd of swine. The ideals which have lighted me on my way and time after time given me new courage to face life cheerfully, have been Truth, Goodness, and Beauty. Without the sense of fellowship with men of like mind, of preoccupation with the objective, the eternally unattainable in the field of art and scientific research, life would have seemed to me empty. The ordinary objects of human endeavor — property, outward success, luxury — have always seemed to me contemptible.

Context: I have never looked upon ease and happiness as ends in themselves — this critical basis I call the ideal of a pigsty. The ideals that have lighted my way, and time after time have given me new courage to face life cheerfully, have been Kindness, Beauty, and Truth. Without the sense of kinship with men of like mind, without the occupation with the objective world, the eternally unattainable in the field of art and scientific endeavors, life would have seemed empty to me. The trite objects of human efforts — possessions, outward success, luxury — have always seemed to me contemptible.

Context: Monsters remain human beings. In fact, to reduce them to a subhuman level is to exonerate them of their acts of terrorism and mass murder — just as animals are not deemed morally responsible for killing. Insisting on the humanity of terrorists is, in fact, critical to maintaining their profound responsibility for the evil they commit.
And, if they are human, then they must necessarily not be treated in an inhuman fashion. You cannot lower the moral baseline of a terrorist to the subhuman without betraying a fundamental value. That is why the Geneva Conventions have a very basic ban on "cruel treatment and torture," and "outrages upon personal dignity, in particular humiliating and degrading treatment" — even when dealing with illegal combatants like terrorists. That is why the Declaration of Independence did not restrict its endorsement of freedom merely to those lucky enough to find themselves on U. S. soil — but extended it to all human beings, wherever they are in the world, simply because they are human.
