From "Why I am a Free Trader" (1905), Churchill revised this several times, the earliest recorded version coming from the speech "For Free Trade" at the Free Trade Hall, Manchester, 19 February 1904:
It is the theory of the Protectionist that imports are an evil. He thinks that if you shut out the foreign imported manufactured goods you will make these goods yourselves, in addition to the goods which you make now, including those goods which we make to exchange for the foreign goods that come in. If a man can believe that he can believe anything. (Laughter.) We Free-traders say it is not true. To think you can make a man richer by putting on a tax is like a man thinking that he can stand in a bucket and lift himself up by the handle. (Laughter and cheers.)
