G.W.F. Hegel was a late 1700s early 1800s philosophy.  He believed that good and bad could not exist because they are constantly negating each other.  So all events and people and societies are in the state of "becoming" as we all move toward perfection.  This is a useful excursive in any Literature class, social sciences class, or even in considering the power science has given us and whether we should use that power (ie. nuclear bombs, stem cell research, Gene modifications, etc).

Help students become more of who they are... not who you are! 

None of us holds the Truth, but we all participate in the Truth.  Knowing that you do not know everything is knowledge in itself and helps all of us get to a better place.  In this sense, be who you are and help your students become who they are.  We're all colors in a kaleidoscope and the light of purpose and self-fulfillment illuminates our way.
