I read a very interesting letter written by William M. Taylor of Oakton Community College from Des Plaines, IL 60016 to his students and I found it quite evocative. I liked his letter for its honest tone. I quote from his letter:
Academic integrity, as with so much in life, involves a system of interconnected rights and responsibilities that reflect our mutual dependence upon one another. The success of our individual efforts in this course, as with so much in life, depends on all of us conscientiously exercising our rights and living up to our responsibilities.
