“Pressure of opinion a hundred years ago brought about the emancipation of the slaves.”

1960s, I Have A Dream (1963)
Context: Five score years ago, a great American, in whose symbolic shadow we stand today signed the Emancipation Proclamation. This momentous decree came as a great beacon light of hope to millions of Negro slaves who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of their captivity. But one hundred years later, we must face the tragic fact that the Negro is still not free.
One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languished in the corners of American society and finds himself an exile in his own land.

Context: About three hundred years ago, it was decreed by the Chief Circle that, since women are deficient in Reason but abundant in Emotion, they ought no longer to be treated as rational, nor receive any mental education. The consequence was that they were no longer taught to read, nor even to master Arithmetic enough to enable them to count the angles of their husband or children; and hence they sensibly declined during each generation in intellectual power. And this system of female non-education or quietism still prevails.My fear is that, with the best intentions, this policy has been carried so far as to react injuriously on the Male Sex.For the consequence is that, as things now are, we Males have to lead a kind of bi-lingual, and I may almost say bi-mental, existence. With Women, we speak of "love", "duty", "right", "wrong", "pity", "hope", and other irrational and emotional conceptions, which have no existence, and the fiction of which has no object except to control feminine exuberances; but among ourselves, and in our books, we have an entirely different vocabulary and I may almost say, idiom. "Love" then becomes "the anticipation of benefits"; "duty" becomes "necessity" or "fitness"; and other words are correspondingly transmuted. Moreover, among Women, we use language implying the utmost deference for their Sex; and they fully believe that the Chief Circle Himself is not more devoutly adored by us than they are: but behind their backs they are both regarded and spoken of — by all except the very young — as being little better than "mindless organisms".

1860s, 1864, Letter to R.M. Sawyer (January 1864)
Context: p>If they want eternal war, well and good; we accept the issue, and will dispossess them and put our friends in their place. I know thousands and millions of good people who at simple notice would come to North Alabama and accept the elegant houses and plantations there. If the people of Huntsville think different, let them persist in war three years longer, and then they will not be consulted. Three years ago by a little reflection and patience they could have had a hundred years of peace and prosperity, but they preferred war; very well. Last year they could have saved their slaves, but now it is too late.All the powers of earth cannot restore to them their slaves, any more than their dead grandfathers. Next year their lands will be taken, for in war we can take them, and rightfully, too, and in another year they may beg in vain for their lives. A people who will persevere in war beyond a certain limit ought to know the consequences. Many, many peoples with less pertinacity have been wiped out of national existence.</p

1920s, The Progress of a People (1924)
Context: Looking back only a few years, we appreciate how rapid has been the progress of the colored people on this continent. Emancipation brought them the opportunity of which they have availed themselves. It has been calculated that in the first year following the acceptance of their status as a free people, there were approximately 4,000,000 members of the race in this country, and that among these only 12,000 were the owners of their homes; only 20,000 among them conducted their own farms, and the aggregate wealth of these 4,000,000 people hardly exceeded $20,000,000. In a little over a half century since, the number of business enterprises operated by colored people had grown to near 50,000, while the wealth of the Negro community has grown to more than $1,100,000,000. And these figures convey a most inadequate suggestion of the material progress. The 2,000 business enterprises which were in the hands of colored people immediately following emancipation were almost without exception small and rudimentary. Among the 50,000 business operations now in the hands of colored people may be found every type of present-day affairs. There are more than 70 banks conducted by thoroughly competent colored business men. More than 80 percent of all American Negroes are now able to read and write. When they achieved their freedom not 10 percent were literate. There are nearly 2,000,000 Negro pupils in the public schools; well-nigh 40,000 Negro teachers are listed, more than 3,000 following their profession in normal schools and colleges. The list of educational institutions devoting themselves to the race includes 50 colleges, 13 colleges for women, 26 theological schools, a standard school of law, and 2 high-grade institutions of medicine. Through the work of these institutions the Negro race is equipping men and women from its own ranks to provide its leadership in business, the professions, in all relations of life.
