The Liberator (1831 - 1866)
Context: I am aware that many object to the severity of my language; but is there not cause for severity? I will be as harsh as truth, and as uncompromising as justice. On this subject, I do not wish to think, or to speak, or write, with moderation. No! no! Tell a man whose house is on fire to give a moderate alarm; tell him to moderately rescue his wife from the hands of the ravisher; tell the mother to gradually extricate her babe from the fire into which it has fallen; — but urge me not to use moderation in a cause like the present. I am in earnest — I will not equivocate — I will not excuse — I will not retreat a single inch — AND I WILL BE HEARD. The apathy of the people is enough to make every statue leap from its pedestal, and to hasten the resurrection of the dead.

As quoted in Conservatives Betrayed: How George W. Bush and other big government Republicans hijacked the conservative cause (2006) by Richard A Viguerie, p. 46 <!-- similar to statement previously dated (16 September 2003) — but linked page indicates "interview" by John Hawkins dated 25 February 2012 http://www.rightwingnews.com/interviews/friedman.php : I am in favor of cutting taxes under any circumstances and for any excuse, for any reason, whenever it's possible. … because I believe the big problem is not taxes, the big problem is spending. The question is, "How do you hold down government spending?" Government spending now amounts to close to 40% of national income not counting indirect spending through regulation and the like. If you include that, you get up to roughly half. The real danger we face is that number will creep up and up and up. The only effective way I think to hold it down, is to hold down the amount of income the government has. The way to do that is to cut taxes. -->
Context: I am in favor of cutting taxes under any circumstances and for any excuse, for any reason, whenever it's possible. … because I believe the big problem is not taxes, the big problem is spending. I believe our government is too large and intrusive, that we do not get our money's worth for the roughly 40 percent of our income that is spent by government … How can we ever cut government down to size? I believe there is one and only one way: the way parents control spendthrift children, cutting their allowance. For government, that means cutting taxes.
