Immanuel Kant on anarchy
The German philosopher Immanuel Kant treated "Anarchy" in his Anthropology from a Pragmatic Point of View as consisting of "Law and Freedom without Force". Thus, for Kant, anarchy falls short of being a true civil state because the law is only an "empty recommendation" if force is not included to make this law efficacious. For there to be such a state, force must be included while law and freedom are maintained, a state which Kant calls republic.
As summary Kant named these four kinds of government:
A Law And Freedom without Violence (Anarchy)
B Law And Violence without Freedom (Despotism)
C Violence without Freedom And Law (Barbarism)
D Violence with Freedom And Law (Republic)
