Abraham Lincoln citations

I will say, then, that I am not nor have ever been in favor of bringing about in any way the social and political equality of the black and white races, that I am not, nor ever have been, in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with White people; and I will say in addition to this that there is a physical difference between the White and black races which will ever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together, there must be the position of

Quoted in 3:439 Herndon's Lincoln (1890), p. 439 http://books.google.com/books?id=rywOAAAAIAAJ&pg=PA439&dq=%22when+i+do+good+i+feel+good%22: Inasmuch as he was so often a candidate for public office Mr. Lincoln said as little about his religious code as possible, especially if he failed to coincide with the orthodox world. In illustration of his religious code I once heard him say that it was like that of an old man named Glenn, in Indiana, whom he heard speak at a church meeting, and who said: "When I do good I feel good, when I do bad I feel bad, and that's my religion."

1860s, Allow the humblest man an equal chance (1860)
Contexte: Slavery is wrong. If Slavery is right, all words, acts, laws, and Constitutions against it, are themselves wrong, and should be silenced, and swept away. If it is right, we cannot justly object to its nationality — its universality; if it is wrong they cannot justly insist upon its extension — its enlargement. All they ask, we could readily grant, if we thought Slavery right; all we ask, they could as readily grant, if they thought it wrong. Their thinking it right, and our thinking it wrong, is the precise fact upon which depends the whole controversy. Thinking it right as they do, they are not to blame for desiring its full recognition, as being right; but, thinking it wrong, as we do, can we yield to them? Can we cast our votes with their view, and against our own? In view of our moral, social, and political responsibilities, can we do this?
Wrong as we think Slavery is, we can yet afford to let it alone where it is, because that much is due to the necessity arising from its actual presence in the nation; but can we, while our votes will prevent it, allow it to spread into the National Territories, and to overrun us here in these Free States?
If our sense of duty forbids this, then let us stand by our duty, fearlessly and effectively. Let us be diverted by none of those sophistical contrivances wherewith we are so industriously plied and belabored — contrivances such as groping for middle ground between the right and the wrong, vain as the search for a man who should be neither a living man nor a dead man — such as a policy of "don't care" on a question about which all true men do care — such as Union appeals beseeching true Union men to yield to Disunionists, reversing the divine rule, and calling, not the sinners, but the righteous to repentance — such as invocations of Washington, imploring men to unsay what Washington did.

This quote is often misattributed to Lincoln. The earliest instance that Quote Investigator could locate was "in an advertisement in 1947 for a book about aging by Edward J. Stieglitz, M.D". The advertisement for “The Second Forty Years” which ran in the Chicago Tribune newspaper read like this: The important thing to you is not how many years in your life, but how much life in your years! (Compare 1947 March 16, Chicago Tribune, “How Long Do You Plan to Live?”, [Advertisement for the book "The Second Forty Years" by Edward J. Stieglitz, M.D.], p. C7, Chicago, Illinois. (ProQuest)).

First attributed to Lincoln in 2002, this seems a paraphrase of a statement in the Lyceum address of 1838, while incorporating language used by Thomas E. Dewey (c. 1944), who said "By the same token labor unions can never be destroyed from the outside. They can only fail if they fail to lend their united support to full production in a free society".
Misattributed

Variante: Those who deny freedom to others deserve it not for themselves, and, under a just God cannot retain it.

This is probably the most famous of apparently apocryphal remarks attributed to Lincoln. Despite it being cited variously as from an 1856 speech, or a September 1858 speech in Clinton, Illinois, there are no known contemporary records or accounts substantiating that he ever made the statement. The earliest known appearance is October 29, 1886 in the Milwaukee Daily Journal http://anotherhistoryblog.blogspot.com/2009/02/fooling-people-earlier.html. It later appeared in the New York Times on August 26 http://query.nytimes.com/gst/abstract.html?res=F30817FF3E5413738DDDAF0A94D0405B8784F0D3 and August 27 http://query.nytimes.com/gst/abstract.html?res=F00E15FF3E5413738DDDAE0A94D0405B8784F0D3, 1887. The saying was repeated several times in newspaper editorials later in 1887. In 1888 and, especially, 1889, the saying became commonplace, used in speeches, advertisements, and on portraits of Lincoln. In 1905 and later, there were attempts to find contemporaries of Lincoln who could recall Lincoln saying this. Historians have not, generally, found these accounts convincing. For more information see two articles in For the People: A Newsletter of the Abraham Lincoln Association, "'You Can Fool All of the People' Lincoln Never Said That", by Thomas F. Schwartz ( V. 5, #4, Winter 2003, p. 1 http://abrahamlincolnassociation.org/Newsletters/5-4.pdf) and "A New Look at 'You Can Fool All of the People'" by David B. Parker ( V. 7, #3, Autumn 2005, p. 1 http://abrahamlincolnassociation.org/Newsletters/7-3.pdf); also the talk page. The statement has also sometimes been attributed to P. T. Barnum, although no references to this have been found from the nineteenth century.
Variants:
You can fool all the people some of the time, and some of the people all of the time, but you cannot fool all of the people all of the time.
You can fool all of the people some of the time, and some of the people all of the time, but you can't fool all of the people all of the time.
You can fool all the people some time, you can fool some of the people all of the time, but you can not fool all the people all the time.

1860s, Allow the humblest man an equal chance (1860)
Contexte: So that saying, "in the struggle between the negro and the crocodile," &c., is made up from the idea that down where the crocodile inhabits a white man can't labor; it must be nothing else but crocodile or negro; if the negro does not the crocodile must possess the earth; [Laughter; ] in that case he declares for the negro. The meaning of the whole is just this: As a white man is to a negro so is a negro to a crocodile; and as the negro may rightfully treat the crocodile, so may the white man rightfully treat the negro. This very dear phrase coined by its author, and so dear that he deliberately repeats it in many speeches, has a tendency to still further brutalize the negro, and to bring public opinion to the point of utter indifference whether men so brutalized are enslaved or not.

1850s, The House Divided speech (1858)
Contexte: Of strange, discordant, and even hostile elements, we gathered from the four winds, and formed and fought the battle through, under the constant hot fire of a disciplined, proud, and pampered enemy. Did we brave all them to falter now? — now, when that same enemy is wavering, dissevered, and belligerent? The result is not doubtful. We shall not fail — if we stand firm, we shall not fail. Wise counsels may accelerate, or mistakes delay it, but, sooner or later, the victory is sure to come.

This is attributed to Lincoln in the 1960 film adaptation of Pollyanna. In reality, it was fabricated by screenwriter and director David Swift, who had to have thousands of lockets bearing the false inscription recalled after Disney began selling them at Disneyland.
