Explanation: The Job advertisement: Explain that the school/college is advertising for a new teacher. Invite students to make some statements about what the new teacher should be like. Write them on board in terms of the teacher (subject) and potential characteristic e.g.) good looking (predicate). Draw two stick men on the board and announce that two suitable candidates have been found.
Explain that the only difference is that one has existence and one does not. Invite student to remove one of the stick men. Ask whether the properties will remain?
Explain Kant’s statement that existence is not a predicate.
Using appropriate resources, students write a paragraph explaining how Kant’s objection can be applied to the Ontological Argument.
