Every bureaucracy, therefore, in accord with the peculiar emphasis on its own position, tends to generalize its own experience and to overlook the fact that the realm of administration and of smoothly functioning order represents only a part of the total political reality. Bureaucratic thought does not deny the possibility of the science of politics, but regards it as identical with the science of administration. Thus irrational factors are overlooked, and when these nevertheless force themselves to the fore, they are treated as "routine matters of state."
