“A well-disciplined militia is a safe, an honorable guard to a community like this, whose inhabitants are by nature brave, and are laudably tenacious of that freedom in which they were born.”
Boston Massacre Oration (1774)
Context: A well-disciplined militia is a safe, an honorable guard to a community like this, whose inhabitants are by nature brave, and are laudably tenacious of that freedom in which they were born. From a well-regulated militia we have nothing to fear; their interest is the same with that of the State. When a country is invaded, the militia are ready to appear in its defense; they march into the field with that fortitude which a consciousness of the justice of their cause inspires; they do not jeopard their lives for a master who considers them only as the instruments of his ambition, and whom they regard only as the daily dispenser of the scanty pittance of bread and water. No; they fight for their houses, their lands, for their wives, their children; for all who claim the tenderest names, and are held dearest in their hearts; they fight pro aris et focis, for their liberty, and for themselves, and for their God.

“Within a militarist community there is no freedom; there are only obedience and discipline.”
Omnipotent Government: The Rise of the Total State and Total War (1944)
Context: The characteristic feature of militarism is not the fact that a nation has a powerful army or navy. It is the paramount role assigned to the army within the political structure. Even in peacetime the army is supreme; it is the predominant factor in political life. The subjects must obey the government as soldiers must obey their superiors. Within a militarist community there is no freedom; there are only obedience and discipline.

Judicial opinions
Context: The defendants' objections to the evidence obtained by wire-tapping must, in my opinion, be sustained. It is, of course, immaterial where the physical connection with the telephone wires leading into the defendants' premises was made. And it is also immaterial that the intrusion was in aid of law enforcement. Experience should teach us to be most on our guard to protect liberty when the government's purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.

“It is a strong castle, and strongly guarded; but there is no impossibility to brave men.”
