The quote is great. It reminds that one should always be willing to experience and learn something new.

Hitler was not elected by the german people. A Chancellor was appointed by the President of Germany and not by an election by the people.
But the President was elected by the people. In the years of 1925 1934 Paul von Hindenburg (conservative) was the President and appointed A.Hitler as Chancellor in 1933.
The NSDAP had never achieved an absolute majority by votes in Germany. The Nazis used instead a a trick (false flag operation -> emergency decree [Enabling Act of 1933]) to enforce their claim of absolute power.
Hindenburg had simply underestimated Hitler. Hindenburg thought he can controll him, but that was a fallacy.

About Prussia:
"Prussia is neither tribe nor race, Prussia is attitude and never mass, Prussia is duty according Immanuel Kant."

"The idea of freedom can never be disassociated from real Prussia. The real Prussian spirit means a synthesis between restraint and freedom, between voluntary subordination and conscientious leadership, between pride in oneself and consideration for others, between rigor and compassion. Unless a balance is kept between these qualities, the Prussian spirit is in danger of degenerating into soulless routine and narrow-minded dogmatism." Generalmajor H.Tresckow, 1943 (German Resistance 'Widerstand')

A human is a human and Prussia is not Russia. Prussia ist Preussen (Berlin - Brandenburg - Silesia).
