Knowledge is a great honor and a great responsibility. Whether we are learning or teaching, we expose ourselves to disagreement, dissent, disgust. As teachers, our students may refuse to listen to the things we tell them -- either because they don't want to learn or because they are frightened by the truths they hear. As students, we open ourselves to revelations that may change our perspective on the world -- and not always in a good way. For as much information that makes us happier in our world, we learn an equal amount that makes us nervous, uncomfortable, or distrustful of others.
