What is Philosophy, Political Science, Economics and Sociology?

Philosophy, Political Science, Economics and Sociology (P.P.E.S.) enables students to study four subjects that are central to understanding any society. It brings together some of the most important approaches to understanding the social and human world, developing skills for a whole range of future careers and activities. The idea behind the programme is that social and human issues need to be approached from different but interrelated viewpoints. For example, political decisions often concern economic matters, and government decisions are often influenced by economic events.

Is it the right course for you?

This course will appeal to students who are excited about the challenges of understanding the way societies are organised, governed and create wealth drawing on the methods and insights of philosophical inquiry. If you are puzzled about the ways our world is structured and have a desire to change it, then this may well be the course for you.

Why study P.P.E.S. at Trinity?

The P.P.E.S. programme is the only university degree in Ireland where students can combine the study of Philosophy, Political Science, Economics and Sociology. Trinity’s School of Social Sciences and Philosophy – where the P.P.E.S. degree finds its home – is at the forefront of research and teaching across the disciplines of Philosophy, Political Science, Economics and Sociology and is Ireland’s top ranked university in all four subjects (QS World University Rankings by Subject 2015).

Trinity has an international reputation for its research on issues of global societal and economic importance such as migration, development, international macroeconomics and political and economic integration in Europe. Our students benefit from a research-led education which exposes them to world-class academics who are committed to providing rigorous, interesting and challenging courses.

What will you study?


In first year you will take all four subjects: Economics (Introduction to Economics, Mathematics and Statistics), Philosophy (Central Problems in Philosophy, History of Philosophy), Political Science (Introduction to Political Science) and Sociology (Introduction to Sociology).


In second year you choose to continue three of the subjects and could, for example, take modules ranging from Economic Principles, to the History of Philosophy to International Politics, to an Introduction to Social Research.


In third year you take two of the four subjects and in fourth year you may take either two subjects or choose to specialise in only one. Students pursuing the equivalent of single honour programmes in their final year will be able to pursue an undergraduate dissertation, and all fourth year modules have elements of project work intended to help develop research skills and the skills of independent enquiry.

Student Profile

Alan Walsh

I found the initial broad subject range extremely useful as it meant I could gain an overview of the social sciences and obtain experience in various different fields before specialising in the later years.
