IB Philosophy
Critical examination of fundamental questions about knowledge, reality, and ethics.
IB Philosophy encourages students to think critically about fundamental questions concerning human existence. Students engage with diverse philosophical traditions while developing skills in argument analysis, logic, and philosophical writing. The current course was first assessed in 2025.

Why Philosophy Matters
Your grade in IB Philosophy counts toward the 45-point Diploma, and many university courses ask for a particular grade in the subject, often at Higher Level.

SL covers the core theme, Being human, one optional theme and one prescribed text in 150 hours of philosophical inquiry.
HL adds a second optional theme and the HL extension, Philosophy and contemporary issues, assessed through an unseen text in Paper 3, in 240 hours.
