“Certainly no valid answer is ever gained by excluding any factors of the problem; that was the Puritans’ error.”

The Paris Review (Spring 1954) http://theparisreview.org/viewinterview.php/prmMID/5114 <!-- This has been appeared in a paraphrased version: Every writer since the beginning of time, just like other people, has been afflicted by what a friend of mine calls "the fleas of life" — you know, colds, hangovers, bills, sprained ankles and little nuisances of one sort or another. -->
Context: Writers ever since writing began have had problems, and the main problem narrows down to just one word — life. Certainly this might be an age of so-called faithlessness and despair we live in, but the new writers haven’t cornered any market on faithlessness and despair, any more than Dostoyevsky or Marlowe or Sophocles did. Every age has its terrible aches and pains, its peculiar new horrors, and every writer since the beginning of time, just like other people, has been afflicted by what that same friend of mine calls “the fleas of life”—you know, colds, hangovers, bills, sprained ankles, and little nuisances of one sort or another. They are the constants of life, at the core of life, along with nice little delights that come along every now and then.

which is extremely arduous, isn’t it? Because, the more I understand the problem, the more significance there is in it. To understand, I must approach it quietly, not impose on the problem my ideas, my feelings of like and dislike. Then the problem will reveal its significance. Why is it not possible to have tranquillity of the mind right from the beginning?

1860s, Letter to James C. Conkling (1863)
Context: But the proclamation, as law, either is valid, or is not valid. If it is not valid, it needs no retraction. If it is valid, it can not be retracted, any more than the dead can be brought to life. Some of you profess to think its retraction would operate favorably for the Union. Why better after the retraction, than before the issue? There was more than a year and a half of trial to suppress the rebellion before the proclamation issued, the last one hundred days of which passed under an explicit notice that it was coming, unless averted by those in revolt, returning to their allegiance. The war has certainly progressed as favorably for us, since the issue of the proclamation as before. I know as fully as one can know the opinions of others, that some of the commanders of our armies in the field who have given us our most important successes, believe the emancipation policy, and the use of colored troops, constitute the heaviest blow yet dealt to the rebellion; and that, at least one of those important successes, could not have been achieved when it was, but for the aid of black soldiers. Among the commanders holding these views are some who have never had any affinity with what is called abolitionism, or with republican party politics; but who hold them purely as military opinions. I submit these opinions as being entitled to some weight against the objections, often urged, that emancipation, and arming the blacks, are unwise as military measures, and were not adopted, as such, in good faith.
