 Creating free citizens and leaders requires that the teachers themselves be actively engaged in their communities as citizens. Teachers should not be prevented from political engagement, as only politically engaged teachers will be able to communicate to their students the love of freedom and fatherland. As he was later to emphasize in his History of Materialism, simply instructing people, including students, to be ethical—to be concerned with the good of humanity in general—does not have much of an impact. In the case of education one can have an impact by presenting a role model and by being a personal inspiration for one’s students.

This personality was the result of, and constituted by, his active engagement with the political issues of his time (Lange 1862).
