The following branches are the main areas of study:

 បរមត្ថវិជ្ជាMetaphysics is the study of the nature of reality, including the relationship between mind and body, substance and accident, events and causation. Traditional branches are cosmology and ontology.
 Epistemology is concerned with the nature and scope of knowledge, and whether knowledge is possible. Among its central concerns has been the challenge posed by skepticism and the relationships between truth, belief, and justification.
 Ethics, or "moral philosophy", is concerned primarily with the question of the best way to live, and secondarily, concerning the question of whether this question can be answered. The main branches of ethics are meta-ethics, normative ethics, and applied ethics. Meta-ethics concerns the nature of ethical thought, such as the origins of the words good and bad, and origins of other comparative words of various ethical systems, whether there are absolute ethical truths, and how such truths could be known.  Normative ethics are more concerned with the questions of how one ought to act, and what the right course of action is.  This is where most ethical theories are generated.http://en.wikipedia.org/wiki/Normative_ethics  Lastly, applied ethics go beyond theory and step into real world ethical practice, such as questions of whether or not abortion is correct.http://en.wikipedia.org/wiki/Applied_ethics Ethics is also associated with the idea of morality, and the two are often interchangeable.
 ទស្សនវិជ្ជានយោបាយPolitical philosophy is the study of government and the relationship of individuals (or families and clans) to communities including the state. It includes questions about justice, law, property, and the rights and obligations of the citizen. Politics and ethics are traditionally inter-linked subjects, as both discuss the question of what is good and how people should live.
 សោភណវិទ្យាAesthetics deals with beauty, art, enjoyment, sensory-emotional values, perception, and matters of taste and sentiment.
 តក្កវិជ្ជាLogic is the study of valid argument forms. Beginning in the late 19th century, mathematicians such as Gottlob Frege focused on a mathematical treatment of logic, and today the subject of logic has two broad divisions: mathematical logic (formal symbolic logic) and what is now called philosophical logic.

Philosophy has expanded to include specialized branches of thought:

 ទស្សនវិជ្ជាច្បាប់Philosophy of law (more commonly called Jurisprudence) explores the varying theories explaining the nature and the interpretations of the law in society.

 ទស្សនវិជ្ជាសាសនាPhilosophy of science
