Moral philosophy is the study of ethics in relation to the ultimate questions of morality. There are two main branches of thought being Metaethics and Normative Ethics.

Metaethics:

Question: What is the nature and methodology of moral judgement?

The study of Metaethics studies the nature and methodology of moral decision and judgment and asks questions along the lines of:

What does “good” and “ought,” mean?

Can we justify moral truths?

Whether there is rationality between right and wrong?

A metaethical view normally consists of two conjoining parts.

1. The definition of “good” choices.
2. The selection of moral principles.

Methods of consonance often base morality on social convention, self-evident truths, God’s will, or personal feeling.

Normative Ethics:

Question: What underlying principles should we live by?

The study of normative ethics is broken down into two levels.

1. Normative Theory – We should maximize everyone’s happiness.
2. Applied Normative Ethics – Studies particular areas such as abortion, suicide and depression.

Both levels defend moral principles and are justifiable ways to explain moral action.

Summary

- Metaethics is the study of nature and methodology of moral judgement and choice. Its main purpose is to justify and rationally defend beliefs about right and wrong.

- Normative ethics is the study how we ‘ought’ to live. It characterises social normality and looks for constraint in arguments about what is worthwhile, right and wrong, just and virtuous.
