I made an interesting discovery yesterday. (I’m sure others have already noticed it, but the insight is new to me.) Many readers will know this famous passage from Martin Luther King’s “Letter from the Birmingham Jail”: 

We have waited for more than 340 years for our constitutional and God given rights. The nations of Asia and Africa are moving with jetlike speed toward gaining political independence, but we still creep at horse and buggy pace toward gaining a cup of coffee at a lunch counter. Perhaps it is easy for those who have never felt the stinging darts of segregation to say, "Wait." But when you have seen vicious mobs lynch your mothers and fathers at will and drown your sisters and brothers at whim; when you have seen hate-filled policemen curse, kick and even kill your black brothers and sisters; when you see the vast majority of your twenty million Negro brothers smothering in an airtight cage of poverty in the midst of an affluent society; when you suddenly find your tongue twisted and your speech stammering as you seek to explain to your six year old daughter why she can't go to the public amusement park that has just been advertised on television, and see tears welling up in her eyes when she is told that Funtown is closed to colored children, and see ominous clouds of inferiority beginning to form in her little mental sky, and see her beginning to distort her personality by developing an unconscious bitterness toward white people; when you have to concoct an answer for a five year old son who is asking: "Daddy, why do white people treat colored people so mean?"; when you take a cross county drive and find it necessary to sleep night after night in the uncomfortable corners of your automobile because no motel will accept you; when you are humiliated day in and day out by nagging signs reading "white" and "colored"; when your first name becomes “n****r," your middle name becomes "boy" (however old you are) and your last name becomes "John," and your wife and mother are never given the respected title "Mrs."; when you are harried by day and haunted by night by the fact that you are a Negro, living constantly at tiptoe stance, never quite knowing what to expect next, and are plagued with inner fears and outer resentments; when you are forever fighting a degenerating sense of "nobodiness"--then you will understand why we find it difficult to wait. There comes a time when the cup of endurance runs over, and men are no longer willing to be plunged into the abyss of despair. I hope, sirs, you can understand our legitimate and unavoidable impatience.

I have taught this essay many, many times over the years, and I have always zeroed in on this passage as an excellent illustration of the use of imitative form. King wants his (largely white) readers to know what it feels like to wait … and wait … and wait … — so he makes those readers wait … and wait … and wait … for the conclusion of the 316-word sentence that’s at the heart of this paragraph.  

Here’s my discovery. Right now I’m teaching Frederick Douglass’s Narrative, and in the final chapter of that mesmerizing book he writes this, an account of his experience as an escaped slave in the North when the Fugitive Slave Act was in effect: 

I have been frequently asked how I felt when I found myself in a free State. I have never been able to answer the question with any satisfaction to myself. It was a moment of the highest excitement I ever experienced. I suppose I felt as one may imagine the unarmed mariner to feel when he is rescued by a friendly man-of-war from the pursuit of a pirate. In writing to a dear friend, immediately after my arrival at New York, I said I felt like one who had escaped a den of hungry lions. This state of mind, however, very soon subsided; and I was again seized with a feeling of great insecurity and loneliness. I was yet liable to be taken back, and subjected to all the tortures of slavery. This in itself was enough to damp the ardor of my enthusiasm. But the loneliness overcame me. There I was in the midst of thousands, and yet a perfect stranger; without home and without friends, in the midst of thousands of my own brethren — children of a common Father, and yet I dared not to unfold to any one of them my sad condition. I was afraid to speak to any one for fear of speaking to the wrong one, and thereby falling into the hands of money-loving kidnappers, whose business it was to lie in wait for the panting fugitive, as the ferocious beasts of the forest lie in wait for their prey. The motto which I adopted when I started from slavery was this — “Trust no man!” I saw in every white man an enemy, and in almost every colored man cause for distrust. It was a most painful situation; and, to understand it, one must needs experience it, or imagine himself in similar circumstances. Let him be a fugitive slave in a strange land — a land given up to be the hunting-ground for slaveholders — whose inhabitants are legalized kidnappers — where he is every moment subjected to the terrible liability of being seized upon by his fellowmen, as the hideous crocodile seizes upon his prey! — I say, let him place himself in my situation — without home or friends — without money or credit — wanting shelter, and no one to give it — wanting bread, and no money to buy it, — and at the same time let him feel that he is pursued by merciless men-hunters, and in total darkness as to what to do, where to go, or where to stay, — perfectly helpless both as to the means of defence and means of escape, — in the midst of plenty, yet suffering the terrible gnawings of hunger, — in the midst of houses, yet having no home, — among fellow-men, yet feeling as if in the midst of wild beasts, whose greediness to swallow up the trembling and half-famished fugitive is only equalled by that with which the monsters of the deep swallow up the helpless fish upon which they subsist, — I say, let him be placed in this most trying situation, — the situation in which I was placed, — then, and not till then, will he fully appreciate the hardships of, and know how to sympathize with, the toil-worn and whip-scarred fugitive slave. 

A brilliant paragraph ending with a 239-word sentence that does exactly what MLK’s still-longer sentence would do more than a century later. I can’t help but think that MLK had this passage from Douglass in mind, if only unconsciously. Where Douglass uses dashes MLK uses semicolons; where Douglass uses “let him” MLK uses “when” — but the strategy and the effect are the same: holding the reader at a point of tension that the writer will offer release from only when the point is well-made. (The ultimate example of this strategy is Wagner’s use of the Tristan chord, which he resolves after fours hours or so, but only a madman would take the business that far.) “Notice how tense you were as you were waiting for the conclusion to that sentence? Imagine that intensified and prolonged by a factor of ten thousand.”
