Well, this seems more than a semantic issue. It looks more like a fairly distorted vision of what 'teaching' means. You can instruct someone to paint like Degas, but your students will then only be that and cannot therefore be called an artist. Teaching is to me to help people to THINK, JUDGE, and have OPINIONS with their own mind and will. Teaching is definitely not telling your student WHAT TO THINK nor HOW TO THINK.
