Or, how a word means exactly what one wants it to mean; nothing more, nothing less.
But there is one point of phraseology which I ought to explain here to forestall any misunderstanding. I use throughout the term “liberal” in the original, nineteenth-century sense in which it is still current in Britain. In current American usage it often means very nearly the opposite of this. It has been part of the camouflage of leftish movements in this country, helped by the muddleheadedness of many who really believe in liberty, that “liberal” has come to mean the advocacy of almost every kind of government control. I am still puzzled why those in the United States who truly believe in liberty should not only have allowed the left to appropriate this almost indispensable term but should even have assisted by beginning to use it themselves as a term of opprobrium. This seems to be particularly regrettable because of the consequent tendency of many true liberals to describe themselves as conservatives.
