Philosophy 123 - 7.2 Knowledge

By the end of this section, you will be able to:

  • Identify and explain the elements of Plato’s traditional account of knowledge.
  • Describe the Gettier problem.
  • Recall a Gettier case and explain how it is a counterexample to the traditional account of knowledge.
  • Identify and explain a way of thinking that attempts to solve the Gettier problem.

What does it mean to say that one knows something? Knowledge is an important concept in all areas of thought. Knowledge is the goal and therefore enjoys a special status. Investigating the nature of knowledge reveals the importance of other concepts that are key to epistemological theorizing—justification in particular.
