Quote by Karl Popper

“The communism of the ruling caste of his best city can thus be derived from Plato’s fundamental sociological law of change; it is a necessary condition of the political stability which is its fundamental characteristic. But although an important condition, it is not a sufficient one. In order that the ruling class may feel really united, that it should feel like one tribe, i.e. like one big family, pressure from without the class is as necessary as are the ties between the members of the class. This pressure can be secured by emphasizing and widening the gulf between the rulers and the ruled. The stronger the feeling that the ruled are a different and an altogether inferior race, the stronger will be the sense of unity among the rulers. We arrive in this way at the fundamental principle, announced only after some hesitation, that there must be no mingling between the classes.”
