“Enjoying things which are pleasant; that is not the evil: it is the reducing of our moral self to slavery by them that is.”

I, 8
The City of God (early 400s)
Context: To the divine providence it has seemed good to prepare in the world to come for the righteous good things, which the unrighteous shall not enjoy; and for the wicked evil things, by which the good shall not be tormented. But as for the good things of this life, and its ills, God has willed that these should be common to both; that we might not too eagerly covet the things which wicked men are seen equally to enjoy, nor shrink with an unseemly fear from the ills which even good men often suffer.
There is, too, a very great difference in the purpose served both by those events which we call adverse and those called prosperous. For the good man is neither uplifted with the good things of time, nor broken by its ills; but the wicked man, because he is corrupted by this world’s happiness, feels himself punished by its unhappiness.

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.

Variant translation: "Before joy, anger, sadness and happiness are expressed, they are called the inner self; when they are expressed to the proper degree, they are called harmony. The inner self is the correct foundation of the world, and harmony is the illustrious Way. When a man has achieved the inner self and harmony, the heaven and earth are orderly and the myriad things are nourished and grow thereby."
As translated by Lin Yutang in The Importance of Living (1937), pp. 143–144

Context: I do not mean to discuss the question how far slavery and farming are incompatible. Our opinions agree as to the evil, moral, political, and economical, of the former.
