Theory of Knowledge (Online)


The theory of knowledge is one of the most central areas of philosophy. In this online course you will cover the key issues in epistemology while also learning to think for yourself and develop your own answers to the core questions in this area.

The theory of knowledge is one of the most central areas of philosophy. In this online course students will cover the key questions in the theory of knowledge, such as: - What is knowledge? - Why is knowledge valuable to us? - What are the sources of knowledge? - Do we really have any knowledge? In examining these questions students will also learn to think for themselves in a clear and critical fashion - that is, they will learn to think philosophically. In so doing they will develop their own answers to the core questions in this area.

Course aims

  • To introduce students to the main themes in the theory of knowledge, such as the problem of scepticism, the various debates regarding how best to understand what knowledge is, and the key issues regarding the sources of knowledge.
  •  To help participants to think clearly and critically.

Course objectives

  • Introduce students to philosophy, and to the critical skills that are involved in doing philosophy.
  • Guide students through the central topics in the theory of knowledge.
  • Enable students to gain a thorough grounding in the key debates in this central area of philosophy.

Teaching methods

  • Guided reading of texts.
  • Group discussions of particular issues.
  • Questions to be answered in personal folders.
  • Debating from positions given rather than from personal belief (to hone skills of debate).

Learning outcomes

By the end of this course students will be expected to have gained the ability to:

  • Think philosophically.
  • Describe the main issues in the theory of knowledge covered by the course.
  • Describe the main distinctions and ideas that these issues trade upon.
  • Constructively criticise the various philosophical positions that you have explored.
  • Develop a position of your own on the key topics covered.

Assessment methods

You will be set two pieces of work for the course. The first of 500 words is due halfway through your course. This does not count towards your final outcome but preparing for it, and the feedback you are given, will help you prepare for your assessed piece of work of 1,500 words due at the end of the course. The assessed work is marked pass or fail.
