Following is a passage that I came across while reading Robert A. Heinlein's "Revolt in 2100". He copyrighted the book in 1954 when the world had recently fought Fascism and Nazi Socialism. Russia's Communism was still going through its growing pains.
Heinlein was very astute in his political observations. In this one, he addresses "Transparency" which is vital to all of us and our well being.

"I began to sense faintly that secrecy is the keystone of all tyranny. Not force, but secrecy... censorship. When any government, or any church for that matter, undertakes to say to its subjects, 'This you may not read, this you may not see, this you are forbidden to know,' the end result is tyranny and oppression, no matter how holy the motives. Mighty little force is needed to control a man whose mind has been hoodwinked; contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, not anything-- you can't conquer a free man; the most you can do is kill him."

With our government trying to "hoodwink" us with their lack of transparency, I feel like we are living what Heinlein was so brilliantly presaging 56 years ago.
