“A standing military force, with an overgrown Executive will not long be safe companions to liberty. The means of defence against foreign danger have been always the instruments of tyranny at home.”

As quoted in Voices of Tomorrow : The 24th Congress of the Communist Party of the Soviet Union (1971) by Jessica Smith, p. 30

Context: Hence, likewise, they will avoid the necessity of those overgrown military establishments, which, under any form of government, are inauspicious to liberty, and which are to be regarded as particularly hostile to Republican Liberty.
Context: While, then, every part of our country thus feels an immediate and particular interest in Union, all the parts combined cannot fail to find in the united mass of means and efforts greater strength, greater resource, proportionably greater security from external danger, a less frequent interruption of their peace by foreign nations; and, what is of inestimable value, they must derive from Union an exemption from those broils and wars between themselves, which so frequently afflict neighbouring countries not tied together by the same governments, which their own rivalships alone would be sufficient to produce, but which opposite foreign alliances, attachments, and intrigues would stimulate and embitter. Hence, likewise, they will avoid the necessity of those overgrown military establishments, which, under any form of government, are inauspicious to liberty, and which are to be regarded as particularly hostile to Republican Liberty. In this sense it is, that your Union ought to be considered as a main prop of your liberty, and that the love of the one ought to endear to you the preservation of the other.

Reaper's Gale (2007)
Context: For Hood's sake,' the foreigner muttered. 'What's wrong with words?'
'With words,' said Redmask, turning away, 'meanings change.'
'Well,' Anaster Toc said, following as Redmask made his way back to his army's camp, 'that is precisely the point. That's their value — their ability to adapt -'
'Grow corrupt, you mean. The Letheri are masters at corrupting words, their meanings. They call war peace, they call tyranny liberty. On which side of the shadow you stand decides a word's meaning. Words are the weapons used by those who see others with contempt. A contempt which only deepens when they see how those others are deceived and made into fools because they choose to believe. Because in their naivety they thought the meaning of a word was fixed, immune to abuse.

As quoted in The Home Book of Quotations, Classical and Modern (1937) edited by Burton Egbert Stevenson

1950s, Give Us the Ballot (1957)
Context: This is no day for the rabble-rouser, whether he be Negro or white. We must realize that we are grappling with the most weighty social problem of this nation, and in grappling with such a complex problem there is no place for misguided emotionalism. We must work passionately and unrelentingly for the goal of freedom, but we must be sure that our hands are clean in the struggle. We must never struggle with falsehood, hate, or malice. We must never become bitter. I know how we feel sometime. There is the danger that those of us who have been forced so long to stand amid the tragic midnight of oppression—those of us who have been trampled over, those of us who have been kicked about—there is the danger that we will become bitter. But if we will become bitter and indulge in hate campaigns, the new order which is emerging will be nothing but a duplication of the old order.
