“Of all people, girls and servants are the most difficult to behave to. If you are familiar with them, they lose their humility. If you maintain a reserve towards them, they are discontented.”

Response in 1965, to Moshe Bejski, one of the Schindlerjuden, who later a became a justice on the Supreme Court of Israel and president of the Commission to honor the Righteous Among the Nations, as quoted in "Schindler : Why did he do it?"

Why our future depends on libraries, reading and daydreaming (2013)
Context: Fiction can show you a different world. It can take you somewhere you've never been. Once you've visited other worlds, like those who ate fairy fruit, you can never be entirely content with the world that you grew up in. Discontent is a good thing: discontented people can modify and improve their worlds, leave them better, leave them different.

Patriotism, or Peace? http://en.wikisource.org/wiki/Patriotism,_or_Peace%3F (1896), translated by Nathan Haskell Dole
Variant:
I have already several times expressed the thought that in our day the feeling of patriotism is an unnatural, irrational, and harmful feeling, and a cause of a great part of the ills from which mankind is suffering, and that, consequently, this feeling – should not be cultivated, as is now being done, but should, on the contrary, be suppressed and eradicated by all means available to rational men. Yet, strange to say – though it is undeniable that the universal armaments and destructive wars which are ruining the peoples result from that one feeling – all my arguments showing the backwardness, anachronism, and harmfulness of patriotism have been met, and are still met, either by silence, by intentional misinterpretation, or by a strange unvarying reply to the effect that only bad patriotism (Jingoism or Chauvinism) is evil, but that real good patriotism is a very elevated moral feeling, to condemn which is not only irrational but wicked.
What this real, good patriotism consists in, we are never told; or, if anything is said about it, instead of explanation we get declamatory, inflated phrases, or, finally, some other conception is substituted for patriotism – something which has nothing in common with the patriotism we all know, and from the results of which we all suffer so severely.
Patriotism and Government http://en.wikisource.org/wiki/Patriotism_and_Government (1900)
Context: Tell people that war is an evil, and they will laugh; for who does not know it? Tell them that patriotism is an evil, and most of them will agree, but with a reservation. "Yes," they will say, "wrong patriotism is an evil; but there is another kind, the kind we hold." But just what this good patriotism is, no one explains.
