Hello philosophers. I have a question I was hoping I could get some insight on. Do teachers have obligations to develop the talents of their students as much as possible? And if they don't, are they in the wrong? If someone who could have been a great pianist becomes an alcoholic, and fails to develop her potential, people sometimes regard that as a tragedy; but is the situation so different to a promising student falling in with a bad teacher, and for that reason failing to develop her potential?
