If the Prussian system was only what it stated, this could be worked with.
However, another piece that this system brings is a non-desire to continue learning.
Because anything more you learn will challenge your doctrines.
Like a religious zealot stating this is the only way to interpret these scriptures.
So, not only are we told what to think, but how to feel about it.
And then our minds are closed, sealed and locked for the rest of our lives.
No place is this more seen then in science. Where you literally have to wait for the old gaurd to die before knew ideas can come into acceptance. When, it should be, rah rah Einstein... but, the speed of light is not constant... rah rah New Theory.
