Go by the question

Each area starts from a question you may already have. What can I know is epistemology. What ought I to do is ethics, what makes reasoning correct is logic, what reality is at bottom is metaphysics, and what beauty is belongs to aesthetics.

A philosophy of something

Many areas take another subject as their object. The philosophy of science asks what separates science from non-science, the philosophy of mind how the mind relates to the body, and the philosophy of law what the law is and how it ought to be. If you already study a subject, its philosophy is a way in.

Questions and answers

What are the main branches of philosophy?

Wikipedia’s article Philosophy names epistemology, ethics, logic and metaphysics as the major branches. Its Outline of philosophy adds aesthetics and lists the rest, from the philosophy of language to political philosophy, under those five or under Other.

What is the difference between ethics and metaethics?

Normative ethics examines the standards by which actions are right or wrong. Metaethics studies the meaning of moral language and the nature of moral judgment itself. Applied ethics, the third branch of ethics, takes up real cases.

What is the difference between metaphysics and ontology?

Metaphysics examines the basic nature and most fundamental structure of reality. Ontology is the philosophical study of being, traditionally understood as the part of metaphysics that deals with the most general features of reality.

Is logic part of philosophy or mathematics?

Both draw on it. Logic is the study of correct reasoning and plays a central role in philosophy, mathematics, computer science and linguistics. The Outline of philosophy lists it as a branch and notes that it is also regarded as a separate formal science.

Which area of philosophy deals with art?

Aesthetics. It studies beauty and taste, and in a broad sense it includes the philosophy of art. The philosophy of film and the philosophy of literature are narrower areas within it.
