“I was ne’er so thrummed since I was a gentleman.”

Speech to his crew off of Puerto San Julian, Argentina, prior to entering the Strait of Magellan (May 1578)
Context: For by the life of God, it doth even take my wits from me to think on it. Here is such controversy between the sailors and gentlemen, and such stomaching between the gentlemen and sailors, it doth make me mad to hear it. But, my masters, I must have it left. For I must have the gentleman to haul and draw with the mariner, and the mariner with the gentleman. What! let us show ourselves to be of a company and let us not give occasion to the enemy to rejoice at our decay and overthrow. I would know him that would refuse to set his hand to a rope, but I know there is not any such here...

In a Parliamentary debate with the Conservative MP, John Pakington (May 31, 1866). Hansard, vol 183, col 1592. Pakington was referring to Footnote 3 to Chapter 7 of Mill's "Considerations on Representative Government".
Misquoted as "I never meant to say that the Conservatives are generally stupid. I meant to say that stupid people are generally Conservative. I believe that is so obviously and universally admitted a principle that I hardly think any gentleman will deny it." in "Life of John Stuart Mill" (1889) by W. L. Courtney, p. 147.
This seems to have become paraphrased as "Conservatives are not necessarily stupid, but most stupid people are conservatives." which was a variant published in Quotations for Our Time (1978), edited by Laurence J. Peter.
