Context: The truth is I've never fooled anyone. I've let people fool themselves. They didn't bother to find out who and what I was. Instead they would invent a character for me. I wouldn't argue with them. They were obviously loving somebody I wasn't. When they found this out, they would blame me for disillusioning them and fooling them.

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.

"As I Please," Tribune (8 December 1944)<sup> http://alexpeak.com/twr/tdoaom/</sup>
"As I Please" (1943–1947)
Context: The important thing is to discover which individuals are honest and which are not, and the usual blanket accusation merely makes this more difficult. The atmosphere of hatred in which controversy is conducted blinds people to considerations of this kind. To admit that an opponent might be both honest and intelligent is felt to be intolerable. It is more immediately satisfying to shout that he is a fool or a scoundrel, or both, than to find out what he is really like. It is this habit of mind, among other things, that has made political prediction in our time so remarkably unsuccessful.

“A man is a fool not to put everything he has, at any given moment, into what he is creating”
As quoted in Shoptalk: learning to write with writers (1990), edited by Donald Morison Murray<!-- Cook Publishers -->
General sources
Context: A man is a fool not to put everything he has, at any given moment, into what he is creating. You're there now doing the thing on paper. You're not killing the goose, you're just producing an egg. So I don't worry about inspiration, or anything like that. It's a matter of just sitting down and working. I have never had the problem of a writing block. I've heard about it. I've felt reluctant to write on some days, for whole weeks, or sometimes even longer. I'd much rather go fishing, for example, or go sharpen pencils, or go swimming, or what not. But, later, coming back and reading what I have produced, I am unable to detect the difference between what came easily and when I had to sit down and say, 'Well, now it's writing time and now I'll write.' There's no difference on paper between the two.

Quoted in Introduction by Terry Newland
Mind is a Myth (1987)
Context: I have assumed that the goal, enlightenment, exists. I have had to search and it is the search itself which has been choking me and keeping me out of my natural state. There is no such thing as spiritual or psychological enlightenment because there is no such thing as spirit or psyche. I have been a damn fool all my life, searching for something which does not exist. My search is at an end.

Cabal of the Cheval Pegasus (1585)
Context: The fools of the world have been those who have established religions, ceremonies, laws, faith, rule of life. The greatest asses of the world are those who, lacking all understanding and instruction, and void of all civil life and custom, rot in perpetual pedantry; those who by the grace of heaven would reform obscure and corrupted faith, salve the cruelties of perverted religion and remove abuse of superstitions, mending the rents in their vesture. It is not they who indulge impious curiosity or who are ever seeking the secrets of nature, and reckoning the courses of the stars. Observe whether they have been busy with the secret causes of things, or if they have condoned the destruction of kingdoms, the dispersion of peoples, fires, blood, ruin or extermination; whether they seek the destruction of the whole world that it may belong to them: in order that the poor soul may be saved, that an edifice may be raised in heaven, that treasure may be laid up in that blessed land, caring naught for fame, profit or glory in this frail and uncertain life, but only for that other most certain and eternal life.

Variant: God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods. But he cannot save them from fool
Source: 1900s, Our National Parks (1901), chapter 10: The American Forests <!-- Terry Gifford, EWDB, pages 604-605 -->
Context: Any fool can destroy trees. They cannot run away; and if they could, they would still be destroyed — chased and hunted down as long as fun or a dollar could be got out of their bark hides, branching horns, or magnificent bole backbones. Few that fell trees plant them; nor would planting avail much towards getting back anything like the noble primeval forests. … It took more than three thousand years to make some of the trees in these Western woods — trees that are still standing in perfect strength and beauty, waving and singing in the mighty forests of the Sierra. Through all the wonderful, eventful centuries … God has cared for these trees, saved them from drought, disease, avalanches, and a thousand straining, leveling tempests and floods; but he cannot save them from fools — only Uncle Sam can do that.
