"One gratifying aspect of our rise to some prominence is that, for the first time in my memory, we, "our side," had captured a crucial word from the enemy. Other words, such as "liberal," had been originally identified with laissez-faire libertarians, but had been captured by left-wing statists, forcing us in the 1940s to call ourselves father feebly "true" or "classical" liberals. "Libertarians"’, in contrast, had long been simply a polite word for left-wing anarchists, that is for anti-private property anarchists, either of the communist or syndicalist variety. But now we had taken it over, and more properly from the view of etymology; since we were proponents of individual liberty and therefore of the individual's right to his property. , p. 83"
