Philosophy and Its Branches

Philosophy:
Oxford dictionary defines philosophy as:
The study of the fundamental nature of knowledge, reality, and existence, especially when considered as an academic discipline.
Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on rational argument. Origin:
Middle English: from Old French philosophie, via Latin from Greek philosophia 'love of wisdom'. Philosophy comes from the Greek for "love of wisdom," giving us two important starting points: love (or passion) and wisdom (knowledge, understanding). Philosophy sometimes seems to be pursued without passion as if it were a technical subject. Although there is a role for dispassionate research, philosophy must derive from some passion for the ultimate goal: a reliable, accurate understanding ourselves and our world.
Branches of philosophy:
The following branches are the main areas of study:
• Metaphysics is the study of the nature of being and the world. 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 with questions of how persons ought to act or if such questions are answerable. The main branches of ethics are meta-ethics, normative ethics, and applied ethics.
• Political philosophy is the study of government and the relationship of individuals and communities to the state.
