“Were it not for imagination, Sir, a man would be as happy in the arms of a chambermaid as of a Duchess.”

Jim Carrey's Unnatural Act (1991)

Said to Abraham Lincoln on the ride back from Lincoln's inauguration as president (4 March 1861); as quoted in James Buchanan (2004) by Jean H. Baker, Pg 140; This or slightly paraphrased variants or abbreviated versions have also been been reported as having been said before the inauguration:
Sir, if you are as happy in entering the White House as I shall feel on returning [home], you are a happy man indeed.
If you are as happy entering the presidency as I am in leaving it, then you are truly a happy man.
As quoted in Presidential Leadership : Rating the Best and the Worst in the White House (2004) edited by James Taranto and Leonard Leo
Earlier variant: Some knave or fool got up a lie from the whole cloth and it was telegraphed over the country that I was about to purchase or had purchased a place somewhere else and would not return to Wheatland. If my successor should be as happy in entering the White House as I shall feel on returning to Wheatland he will indeed be a happy man. I am just now in my own mind chalking out the course of my last message. In it, should Providence continue his blessing, I shall have nothing to record but uninterrupted success for my country. The trouble about the slavery question would all have been avoided, had the Country submitted to the decision of the Supreme Court delivered two or three days after my inaugural.
Letter to William Carpenter (13 September 1860); as published in Historical Papers and Addresses of the Lancaster County Historical Society.

Context: For what imaginable purpose was man made, if not to be "happy"? By victorious Analysis, and Progress of the Species, happiness enough now awaits him. Kings can become philosophers; or else philosophers Kings. Let but Society be once rightly constituted,—by victorious Analysis. The stomach that is empty shall be filled; the throat that is dry shall be wetted with wine. Labour itself shall be all one as rest; not grievous, but joyous Wheat-fields, one would think, cannot come to grow untilled; no man made clayey, or made weary thereby;—unless indeed machinery will do it? Gratuitous Tailors and Restaurateurs may start up, at fit intervals, one as yet sees not how. But if each will, according to rule of Benevolence, have a care for all, then surely—no one will be uncared for. Nay, who knows but by sufficiently victorious Analysis, "human life may be indefinitely lengthened," and men get rid of Death, as they have already done of the Devil? We shall then be happy in spite of Death and the Devil.

Nobody laughed, but we were still all glad he said it.

Context: As I’ve mentioned elsewhere, I’m a Total Disnoid. Walt Disney is one of my heroes: it’s extraordinary what one man, armed only with will and imagination, accomplished. To be a part of that history, that legacy — in any small way — is really an honor.
