“ARTS is a somewhat conservative magazine but it is not uniformly, simply or blindly conservative, and the several conservative writers vary. And I am certainly not a conservative and neither is Miss Harrison. I decidedly disagree with the basic positions of Mr. Kramer, Miss Raynor and Mr. Tillim, though not with some of their evaluations, both of conservative and nonconservative artists. I think Ben Johnson's paintings, for example, are relatively uninteresting and powerless and that the work of some of the dop artists is full of true emotion. uninteresting and powerless and that the work of some of the dop artists is full of true emotion. The conservatism of Mr. Kramer and Mr. Mellow as successive editors lies only in the publication of more articles on conservative artists than on unconservative ones. Neither editors ever suggested to me that the magazine should have a uniform position or attempt to control my reviews, which are often contrary to Mr. Kramer’s opinions.”

Roosevelt here slightly misquotes Thomas Babington Macaulay, who in a speech on parliamentary reform (2 March 1831) asserted: "The voice of great events is proclaiming to us, Reform, that you may preserve."
1930s, Address at the Democratic State Convention, Syracuse, New York (1936)
Context: The true conservative seeks to protect the system of private property and free enterprise by correcting such injustices and inequalities as arise from it. The most serious threat to our institutions comes from those who refuse to face the need for change. Liberalism becomes the protection for the far-sighted conservative.
Never has a Nation made greater strides in the safeguarding of democracy than we have made during the past three years. Wise and prudent men — intelligent conservatives — have long known that in a changing world worthy institutions can be conserved only by adjusting them to the changing time. In the words of the great essayist, "The voice of great events is proclaiming to us. Reform if you would preserve." I am that kind of conservative because I am that kind of liberal.

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.
