[T]hey… have always held… The people are made to transfer their allegiance from the old gods to the new under the pretense that the new gods really are what their sound instinct had always told them but what before they had only dimly seen. And the most effective way to this end is to use the old words but change their meaning.
Few traits of totalitarian regimes are at the same time so confusing to the superficial observer and yet so characteristic of the whole intellectual climate as the complete perversion of language, the change of meaning of the words by which the ideals of the new regimes are expressed….
If one has not one’s self experienced this process, it is difficult to appreciate the magnitude of this change of the meaning of words, the confusion it causes, and the barriers to any rational discussion which it creates… And the confusion becomes worse because this change of meaning of words describing political ideals is not a single event but a continuous process, a technique employed consciously or unconsciously to direct the people. Gradually, as this process continues, the whole language becomes despoiled, and words become empty shells deprived of any definite meaning, as capable of denoting one thing as its opposite and used solely for the emotional associations which still adhere to them.” – Friedrich Hayek, The Road to Serfdom
