ABSTRACT
The starter exercises drew your attention to the difference between ideas and ideas expressed in reality. For example, you can recognise a cat because you know what a cat is, i.e. you have an idea of what a cat is. For Plato this distinction is crucial. First, the knowledge of what a cat is precedes your actually seeing a cat. Second, Plato suggests that the world we live in is a world of appearances but the real world is a world of ideas that he calls Forms.
