Since we are focusing on ethics, we are concerned with what morally ought to be the case.
All ethical theories use various normative ethical principles in assessing actions and behavior.
To be workable and beneficial, ethical discourse must use understandings and procedures, and judgment criteria which all people concerned with morality and ethics must affirm. We need to understand that ethical principles must be the ground rules for our moral decision making - they should not simply be factors we take into consideratin. You must use the theory , of which the principles are a part, to justify your position, not simply list or define the principles. Review your notes for Ethical Analysis and the book by Douglas Birsch, Ethical Insights . Also, review very closely the Moral Reasoning Guidelines for the appropriate evaluation, discovery, and justification procedures.
