Robert A. Heinlein

Robert Anson Heinlein was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers", he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally.

Secrecy is the keystone to all tyranny. Not force, but secrecy and censorship. When any government or church for that matter, undertakes to say to its subjects, "This you may not read, this you must not know," the end result is tyranny and oppression, no matter how holy the motives. Mighty little force is needed to control a man who has been hoodwinked in this fashion; contrariwise, no amount of force can control a free man, whose mind is free.

At least once every human should have to run for his life, to teach him that milk does not come from supermarkets, that safety does not come from policemen, that 'news' is not something that happens to other people.

Specialization is for insects.
[T]here seems to have been an actual decline in rational thinking. The United States had become a place where entertainers and professional athletes were mistaken for people of importance. They were idolized and treated as leaders; their opinions were sought on everything and they took themselves just as seriously-after all, if an athlete is paid a million or more a year, he knows he is important ... so his opinions of foreign affairs and domestic policies must be important, too, even though he proves himself to be ignorant and subliterate every time he opens his mouth.
