“I am a member of a Liberal Government. I am in association with the Liberal party. I have never swerved from what I conceived to be those truly Conservative objects and desires with which I entered life. I am, if possible, more fondly attached to the institutions of my country than I was when as a boy I wandered among the sand-hills of Seaforth or the streets of Liverpool. But experience has brought with it its lessons. I have learnt that there is wisdom in a policy of trust, and folly in a policy of mistrust. I have not refused to receive the signs of the times. I have observed the effect that has been produced by Liberal legislation, and if we are told…that all the feelings of the country are in the best and broadest sense Conservative,—that is to say, that the people value the country and the laws and institutions of the country; if we are told that, I say honesty compels us to admit that result has been brought about by Liberal legislation.”

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."

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.

Context: Well, I would say that, as long-term institutions, I am totally against dictatorships. But a dictatorship may be a necessary system for a transitional period. At times it is necessary for a country to have, for a time, some form or other of dictatorial power. As you will understand, it is possible for a dictator to govern in a liberal way. And it is also possible for a democracy to govern with a total lack of liberalism. Personally I prefer a liberal dictator to democratic government lacking liberalism. My personal impression — and this is valid for South America — is that in Chile, for example, we will witness a transition from a dictatorial government to a liberal government. And during this transition it may be necessary to maintain certain dictatorial powers, not as something permanent, but as a temporary arrangement.
