“An unfamiliar city is a fine thing. That's the time and place when you can suppose that all the people you meet are nice. It's dream time.”

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.

In the sermon titled "The Use of Money" Wesley said, "Employ whatever God has entrusted you with in doing good, all possible good, in every possible kind and degree . . . to all men." This sermon is in the collection titled "Wesley's Standard Sermons." They are called "standard" because all Methodist preachers were instructed to read them and use them in interpreting the Christian faith.
