Curtiss Martin

“English is the largest of human tongues, with several times the vocabulary of the second largest language -- this alone made it inevitable that English would eventually become, as it did, the lingua franca of this planet, for it is thereby the richest and most flexible -- despite its barbaric accretions . . . or, I should say, because of its barbaric accretions. English swallows up anything that comes its way, makes English out of it.”
― Robert A. Heinlein, Stranger in a Strange Land

“Sin lies only in hurting others unnecessarily. All other "sins" are invented nonsense.”
― Robert A. Heinlein

“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”
― Robert A. Heinlein

“Secrecy begets tyranny.”
― Robert A. Heinlein, Stranger in a Strange Land
