“The instant case involves liberty of the person both in its spatial and more transcendent dimensions…. Bowers was not correct when it was decided, and it is not correct today…. As the Constitution endures, persons in every generation can invoke its principles in their own search for greater freedom.”

Context: If you like somebody's work -- just go and see them. However, don't ask for their autograph. A lot of people came and asked me for my autograph -- and it's creepy. What I did is read everything they published first... and correct them. That's what they really want. Every smart person wants to be corrected, not admired.

Section 2 : The Biological Miscalculation in the Human Struggle for Freedom
The Mass Psychology of Fascism (1933), Ch. 10 : Work Democracy
Context: If "freedom" means, first of all, the responsibility of every individual for the rational determination of his own personal, professional and social existence, then there is no greater fear than that of the establishment of general freedom. Without a thoroughgoing solution of this problem there never will be a peace lasting longer than one or two generations. To solve this problem on a social scale, it will take more thinking, more honesty and decency, more conscientiousness, more economic, social and educational changes in social mass living than all the efforts made in previous and future wars and post-war reconstruction programs taken together.

Original: Prima di mancare di rispetto ad una persona corretta, pensaci bene. Una persona corretta, tale gesto lo ricorda per tutta la vita.

1850s, Speech on the Dred Scott Decision (1857)
Context: We believe … in obedience to, and respect for the judicial department of government. We think its decisions on Constitutional questions, when fully settled, should control, not only the particular cases decided, but the general policy of the country, subject to be disturbed only by amendments of the Constitution as provided in that instrument itself. More than this would be revolution. But we think the Dred Scott decision is erroneous. … If this important decision had been made by the unanimous concurrence of the judges, and without any apparent partisan bias, and in accordance with legal public expectation, and with the steady practice of the departments throughout our history, and had been in no part, based on assumed historical facts which are not really true; or, if wanting in some of these, it had been before the court more than once, and had there been affirmed and re-affirmed through a course of years, it then might be, perhaps would be, factious, nay, even revolutionary, to not acquiesce in it as a precedent.
