Like many others, students think that 'knowledge' is a self-explanatory concept. Unless anybody's opinions on this subject are asked, people do not have any problems with ‘knowledge’ or ‘to know something’. In other words, in ordinary life, there is no problem with this concept until somebody asks a question about it. As long as you are not asked what the knowledge and to know is, you know exactly what the knowledge is.

Defined narrowly, epistemology is the study of knowledge and justified belief. As the study of knowledge, epistemology is concerned with the following questions: What are the necessary and sufficient conditions of knowledge? What are its sources? What is its structure, and what are its limits? As the study of justified belief, epistemology aims to answer questions such as: How we are to understand the concept of justification? What makes justified beliefs justified? Is justification internal or external to one's own mind? Understood more broadly, epistemology is about issues having to do with the creation and dissemination of knowledge in particular areas of inquiry. This course will provide a systematic overview of the problems that the questions above raise and focus in some depth on issues relating to the structure and the limits of knowledge and justification.

In addition, this course aims to engage in contemporary epistemology discussions as a continuation of Epistemology 1 course.
