“The more someone assures you that everything is okay, the more you can be assured that it's not.”

Speech to the National Association of Broadcasters, May 9, 1961 (the Wasteland Speech)
Context: When television is good, nothing--not the theater, not the magazines or newspapers--nothing is better.
But when television is bad, nothing is worse. I invite you to sit down in front of your television set when your station goes on the air and stay there without a book, magazine, newspaper, profit and-loss sheet or rating book to distract you--and keep your eyes glued to that set until the station signs off. I can assure you that you will observe a vast wasteland.

Context: I want to assure you that regardless of your circumstances, age, or sex, you can indeed start over, re-arousing from within yourself those earlier, more innocent expectations, feelings and beliefs. It is much better if you can imagine this endeavor more in the light of children’s play, in fact, rather than think of it as a deadly serious adult pursuit.

Context: I feel no inclination to retaliate for the offences of irresponsible persons; but if it is the policy of any General intrusted with the command of troops to show no quarter, or to punish with death prisoners taken in battle, I will accept the issue. It may be you propose a different line of policy towards black troops, and officers commanding them, to that practiced towards white troops. So, I can assure you that these colored troops are regularly mustered into the service of the United States. The Government, and all officers under the Government, are bound to give the same protection to these troops that they do to any other troops.
