“Siri, define knowledge”, you might ask your intelligent assistant, to get a simple definition for the word knowledge. Sure anybody can easily grab their smartphone and get a basic understanding of the word, but what does the word in a philosophical sense actually mean? A very long time ago Philosophers already had a definition of their own. They originally held that knowledge was a belief that was both true and justified.

They argue that you do not need any kind of mental state in order for it to be knowledge. Others defend their doubt of the justified true belief theory by stating how certain animals know how to do things even if they do not believe anything. You can know how to act in some sort of way and that is sufficient. According to Gettier having justified true belief is not satisfactory for knowledge. An individual needs much more than just a justified true belief to having knowledge about something. He says that the JTB theory may initially be plausible, but it turns out to be false. In order to demonstrate his point of view and better support his argument he provides two examples known as Case 1 and Case
