The Department of Philosophy of the University of Kelaniya was established in 1959, on the very same day that the University was established. In addition to Philosophy, the Department offers Degrees in two other subject areas. They are: Psychology and Peace and Conflict Resolution. Since the beginning, Philosophy was the Department’s principal and central study. In the year 2000, as a part of the Department modernizing project, General Degree was introduced to study Psychology; and in 2008 an Especial Degree was introduced to study the same subject. In 2005 “Peace and Conflict Resolution” was introduced as a new study area.

Philosophy is often hailed as the “Science of all Sciences”. This is a historical and a factual truth almost all the fundamental Sciences grew out of Philosophy. And Philosophy studies the abstract principles of all other sciences. The Department studies the traditional branches of philosophy such as Metaphysics, Ethics and Logic. It also studies newly introduced sub divisions such as Philosophy of Law and Philosophy of Science. The department has focused its attention on recently emerged applied areas too. For example, Feminist Philosophy, Philosophical Psychology and Environmental Ethics.
