“The mountain air is fine at evening of the day
And flying birds return together homewards.
Within these things there is a hint of Truth,
But when I start to tell it, I cannot find the words.”

Context: These fellow-mortals, every one, must be accepted as they are: you can neither straighten their noses, nor brighten their wit, nor rectify their dispositions; and it is these people — amongst whom your life is passed — that it is needful you should tolerate, pity, and love: it is these more or less ugly, stupid, inconsistent people whose movements of goodness you should be able to admire — for whom you should cherish all possible hopes, all possible patience. And I would not, even if I had the choice, be the clever novelist who could create a world so much better than this, in which we get up in the morning to do our daily work, that you would be likely to turn a harder, colder eye on the dusty streets and the common green fields — on the real breathing men and women, who can be chilled by your indifference or injured by your prejudice; who can be cheered and helped onward by your fellow-feeling, your forbearance, your outspoken, brave justice.
So I am content to tell my simple story, without trying to make things seem better than they were; dreading nothing, indeed, but falsity, which, in spite of one's best efforts, there is reason to dread. Falsehood is so easy, truth so difficult. The pencil is conscious of a delightful facility in drawing a griffin — the longer the claws, and the larger the wings, the better; but that marvellous facility which we mistook for genius is apt to forsake us when we want to draw a real unexaggerated lion. Examine your words well, and you will find that even when you have no motive to be false, it is a very hard thing to say the exact truth, even about your own immediate feelings — much harder than to say something fine about them which is not the exact truth.

Context: I cannot recall what I started to tell you, but at least
I can say how night-long I have lain under the stars and
Heard mountains moan in their sleep. By daylight,
They remember nothing, and go about their lawful occasions
Of not going anywhere except in slow disintegration. At night
They remember, however, that there is something they cannot remember.
So moan. Their's is the perfected pain of conscience that
Of forgetting the crime, and I hope you have not suffered it. I have.

Context: The person who merely watches the flight of a bird gathers the impression that the bird has nothing to think of but the flapping of its wings. As a matter of fact this is a very small part of its mental labor. To even mention all the things the bird must constantly keep in mind in order to fly securely through the air would take a considerable part of the evening. If I take this piece of paper, and after placing it parallel with the ground, quickly let it fall, it will not settle steadily down as a staid, sensible piece of paper ought to do, but it insists on contravening every recognized rule of decorum, turning over and darting hither and thither in the most erratic manner, much after the style of an untrained horse. Yet this is the style of steed that men must learn to manage before flying can become an everyday sport. The bird has learned this art of equilibrium, and learned it so thoroughly that its skill is not apparent to our sight. We only learn to appreciate it when we try to imitate it.
