"There is no such thing as an achieved liberty; like electricity, there can be no substantial storage and it must be generated as it is enjoyed, or the lights go out."

“But when notice is a person's due, process which is a mere gesture is not 'due process.'”

“No longer may the head of a state consider himself outside of the law, and impose inhuman acts on the peoples of the world.”

“While the Declaration was directed against an excess of authority, the Constitution was directed against anarchy.”

“I should concur in this result more readily if the Court could reach it by analysis of the statute instead of by psychoanalysis of Congress. When we decide from legislative history, including statements of witnesses at hearings, what Congress probably had in mind, we must put ourselves in the place of a majority of Congressmen and act according to the impression we think this history should have made on them. Never having been a Congressman, I am handicapped in that weird endeavor. That process seems to me not interpretation of a statute but creation of a statute.”

“No one will question that this power is the most dangerous one to free government in the whole catalogue of powers. It usually is invoked in haste and excitement when calm legislative consideration of constitutional limitation is difficult. It is executed in a time of patriotic fervor that makes moderation unpopular. And, worst of all, it is interpreted by judges under the influence of the same passions and pressures. Always, as in this case, the Government urges hasty decision to forestall some emergency or serve some purpose and pleads that paralysis will result if its claims to power are denied or their confirmation delayed.”

“The Court's reasoning adds up to this: The Commission must be sustained because of its accumulated experience in solving a problem with which it had never before been confronted! I give up. Now I realize fully what Mark Twain meant when he said, 'The more you explain it, the more I don't understand it.'”
