Stage Three - Argument Maps

Introducing Argument Maps

  • Argument maps are graphical representations of argument structure. Vertical lines indicate inferences, and horizontal lines indicate premises working together.

  • Inferences can be stacked as deep as you want by putting vertical lines underneath premises (giving an argument for that premise).

  • Having two vertical lines off a single conclusion indicates multiple independent lines of argument for that conclusion.

The rules

  • The premises of an inference support only the conclusion of that inference (the claim directly above).

  • No inferences inside a premise.

  • Every inference must contain a primary premise and a linking premise.

  • Always use complete sentences.
