All for Australia (1984)
“Majorities, as such, afford no guarantees for justice. They are men of the same nature as minorities. They have the same passions for fame, power, and money, as minorities; and are liable and likely to be equally — perhaps more than equally, because more boldly — rapacious, tyrannical and unprincipled, if intrusted with power. There is no more reason, then, why a man should either sustain, or submit to, the rule of the majority, than of a minority.”

Speech before the Federal Club http://www.theodore-roosevelt.com/images/research/txtspeeches/581.pdf, New York City, (6 March 1891), as published in New York Daily Tribune (7 March 1891)
1890s
Context: Of recent years... representative government all over the world has been threatened with a growing paralysis. Legislative bodies have tended more and more to become wholly inefficient for the purposes of legislation. The prime feature in causing this unhealthy growth has been the discovery by minorities that under the old rules of parliamentary procedure they could put a complete stop to all legislative action... If the minority is as powerful as the majority there is no use of having political contests at all, for there is no use in having a majority.

The History of Freedom in Antiquity (1877)
Context: It is bad to be oppressed by a minority, but it is worse to be oppressed by a majority. For there is a reserve of latent power in the masses which, if it is called into play, the minority can seldom resist. But from the absolute will of an entire people there is no appeal, no redemption, no refuge but treason.
