Managerial work—the organization and integration of human effort into purposeful, large-scale, long-range activities—is, in the realm of action, what man’s conceptual faculty is in the realm of cognition.
If there is any one proof of a man’s incompetence, it is the stagnant mentality of a worker (or of a professor) who, doing some small, routine job in a vast undertaking, does not care to look beyond the lever of a machine (or the lectern of a classroom), does not choose to know how the machine (or the classroom) got there or what makes his job possible, and proclaims that the management of the undertaking is parasitical and unnecessary.
