One cannot develop moral forces by talking at children or by moralizing, but by doing certain things with the cildren over and over again, by emphasis on the element of will. One must count on the metamorphosis of soul forces: what one has incorporated into the will of the growing child changes and comes to life later as moral feeling and moral imagination. It awakens as a new moral consciousness with the impulse to do in freedom and with love what necessity and duty require.
–Neidermeyer and Frohlich
As a resource for deepening your own understanding of how to use and present form drawing, I can’t recommend Neiderhauser and Frohlich’s work highly enough. If you are new to form drawing, I would suggest that either Form Drawing for Beginners or Form Drawing Grades One through Four would be better places to start — but don’t forget about this one. I promise, you’ll want to dive into it once you feel you have your feet on the ground!
