Context: The title of this book is Our New National Labor Policy, the Taft-Hartley Act and the Next Steps. Get that: "The Next Steps" … They're going even further! … The Republicans favor a minimum wage — the smaller the minimum the better.
Context: Your old friend Congressman Hartley of the Taft Hartley team … has written a book … The title of this book is Our New National Labor Policy, the Taft-Hartley Act and the Next Steps. Get that: "The Next Steps" … They're going even further! … The Republicans favor a minimum wage — the smaller the minimum the better.
Context: Republicans approve of the American farmer, but they are willing to help him go broke. They stand four-square for the American home--but not for housing. They are strong for labor--but they are stronger for restricting labor's rights. They favor minimum wage--the smaller the minimum wage the better. They endorse educational opportunity for all--but they won't spend money for teachers or for schools. They think modern medical care and hospitals are fine--for people who can afford them.... They think American standard of living is a fine thing--so long as it doesn't spread to all the people. And they admire the Government of the United States so much that they would like to buy it. − Harry S. Truman, October 13, 1948, St. Paul, Minnesota, Radio Broadcast.

Promoting "Crocker's Rules" at SL4 (c. 2000) http://www.sl4.org/crocker.html
Context: Declaring yourself to be operating by "Crocker's Rules" means that other people are allowed to optimize their messages for information, not for being nice to you. Crocker's Rules means that you have accepted full responsibility for the operation of your own mind — if you're offended, it's your fault. Anyone is allowed to call you a moron and claim to be doing you a favor. (Which, in point of fact, they would be. One of the big problems with this culture is that everyone's afraid to tell you you're wrong, or they think they have to dance around it.) Two people using Crocker's Rules should be able to communicate all relevant information in the minimum amount of time, without paraphrasing or social formatting. Obviously, don't declare yourself to be operating by Crocker's Rules unless you have that kind of mental discipline.
Note that Crocker's Rules does not mean you can insult people; it means that other people don't have to worry about whether they are insulting you. Crocker's Rules are a discipline, not a privilege. Furthermore, taking advantage of Crocker's Rules does not imply reciprocity. How could it? Crocker's Rules are something you do for yourself, to maximize information received — not something you grit your teeth over and do as a favor.

I am
Context: I am' itself is God. The seeking itself is God. In seeking you discover that you are neither the body nor the mind, and the love of the self in you is for the self in all. The two are one. The consciousness in you and the consciousness in me, apparently two, really one, seek unity and that is love.
