The textbook does not distinguish between "Ethics" and "Morality", as for instance, page 411 states, "To many people, ethics or morality is an automatic response". The two words seem to be clubbed together as one, when in fact there is a subtle distinction. The difference between the two is: Ethics is a subject which studies the object called Morality.
In other words, Ethics is a field of study, whereas Morality is what is "out there". It is like the difference between Medicine, which is a field of study, and the human body, which is the object of study.
This is clearly brought out by the Professor of Philosophy at the University of California at San Diego, Lawrence M. Hinman in his Glossary on Ethics (http://ethics.sandiego.edu/Glossary.html), where he writes:
"Ethics. The explicit, philosophical reflection on moral beliefs and practices. The difference between ethics and morality is similar to the difference between musicology and music. Ethics is a conscious stepping back and reflecting on morality, just as musicology is a conscious reflection on music."
