My ethics book came today that my class will be using. It’s Normative Ethics by Shelly Kagan. I am reading the introduction and it already looks good.
Shelly explains that there are really three different divisions in the field of ethics: Meta-ethics, normative ethics, and applied ethics. As you can tell by the title, this book is about normative ethics.
Normative ethics deals with the question of what ought to be. For example, we ought not kill humans, is a normative ethical principle. It tells us that we should not or ought not kill humans. The field of normative ethics seeks to tell us what is the best way we ought to live. What moral prinicples are there? What is the correct set of moral beliefs?
Now there is a sharp distiction between what is and what ought to be the case. These two should never be confused. For instance, an anthropologist can go to a foreign culture, observe their moral principles, and report back to us what they are. However, this account of their beilefs about moral prinicples does not tell us whether they are the correct ones or not. This report only tells us what is the case, not what should be the case.
This important distiction is lost sometimes when people make the following arguement: Look, every culture has different codes of morality and conceptions of what is right and wrong, so therefore morality is relative to cultures, there is no objective moral code for everyone to follow. This is not a good argument because observations about the moral codes of a society don’t tell us whether or not this is a good moral code or not. This is not a good argument for moral relativism.
Applied ethics is basically normative ethical principles put into practice. The principles are applied to a situation to find out what one should do in that specific situation.
Meta-ethics is a field of discussion about the nature of wrongness and justification. It asks questions such as: What does it mean for something to be wrong? Whats the definition of right and wrong and good and evil? Can we know anything about ethics? Are there any ethical principles? These are more abstract questions that meta-ethics seeks to answer.
So then we can put the entire field of ethics on some sort of continuum. (Some philosophers try to draw very sharp divisions between meta-ethics and normative ethics, claiming that one does not influence the other; however, I along with Kagan, disagree) The continuum looks something like this:
Meta ethics————-normative ethics————–applied ethics
Where we move from the abstract on the left to the more specific and practical on the right. The views of meta-ethics will influence the normative ethical theories you produce and thus also the way you apply them.
So this is a broad introduction to the field of philosophical ethics.
