We are beginning a new era in our government. I cannot too strongly urge the necessity of a rigid economy and an inflexible determination not to enlarge the income beyond the real necessities of the government.
Andrew Jackson
Charisma becomes the undoing of leaders. It makes them inflexible, convinced of their own infallibility, unable to change.
Peter Drucker
Dialectics gives expression to a law which is felt in all grades of consciousness and in general experience. Everything that surrounds us may be viewed as an instance of dialectic. We are aware that everything finite, instead of being inflexible, is rather changeable and transient; and this is exactly what we mean by the dialectic of the finite, by which the finite, as implicitly other than it is, is forced to surrender its own immediate or natural being, and turn suddenly into its opposite.
Georg Wilhelm Friedrich Hegel
But an officer on duty knows no one -- to be partial is to dishonor both himself and the object of his illadvised favor. What will be thought of him who exacts of his friends that which disgraces him? Look at him who winks at and overlooks offences in one, which he causes to be punished in another, and contrast him with the inflexible soldier who does his duty faithfully, notwithstanding it occasionally wars with his private feelings. The conduct of one will be venerated and emulated, the other detested as a satire upon soldiership and honor.
WIlliam Jenkins Worth
Terror is only justice: prompt, severe and inflexible; it is then an emanation of virtue; it is less a distinct principle than a natural consequence of the general principle of democracy, applied to the most pressing wants of the country.
Maximilien Robespierre
