“But only a ruler who is himself enlightened and has no far of phantoms, yet who likewise has at hand a well-disciplined and numerous army to guarantee public security, may say what no republic would dare to say: Argue as much as you like and about whatever you like, but obey!”
Words that I relate to “The Prince” by Machiavelli, a how to be a prince guide written by a prince. The main idea behind it is that its better to be respected and feared, than it is to be loved.
The two are related to me as Kant is saying that a ruler can only say believe, and argue about what you want, as long as by the end of the day you obey my command. Something that at the time, and still to this day can only be done when you have no clear enemies of a certain belief at your doorstep, and have a people to back you, such as the army.
