Love is that condition in which the happiness of another person is essential to your own.
Robert A. HeinleinSecrecy 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. No, not the rack nor the atomic bomb, not anything. You can't conquer a free man; the most you can do is kill him.

Robert A. HeinleinThe bugs are not like us. The Pseudo-Arachnids arenโt even like spiders. They are arthropods who happen to look like a madmanโs conception of a giant intelligent spider, but their organization, psychological and economic, is more like that of ants or termites; they are communal entities, the ultimate dictatorship of the hive.
