Philosophy is the study of the fundamental nature of reality, existence and truth. The course is split into three distinct disciplines, The Philosophy of Religion, Ethics and Developments in Religious thought. Each one enables students to ask questions related to reality and the contemporary world that they experience. Philosophy offers students a definitive pathway into higher education and promotes skills that will be required from university onwards such as Critical thinking.

Each branch of Philosophy perfectly complements the next and is perfectly balanced to give students a well-rounded philosophy based learning experience that enables students to gain insight into how the world can be perceived and provides them with the skills to think about moral issues from a range of alternative points of view. Philosophy gives students the perfect grounding for developing a positive world view as well as promoting a healthy desire to question all aspects of life, knowledge and reality.
