Lesson 4 Learning Objectives: 

  • Identify and distinguish between arguments that have multiple independent premises and those in which one premise supports another premise.
  • Visually represent these basic argument structure types.

Every argument – no matter how simple or how complex – has a structure. Argument mapping allows us to visualize that structure so we can clearly see how reasons fit together to support a claim.

So far, you have just looked at the simplest kind of argument: a main claim supported by a single premise. But most arguments have more than one premise – that’s what makes them interesting! 

There are several basic argument structure types, which we will introduce to you one at a time. These basic structure types can then be combined to make all the complex and interesting arguments that the world has to offer!

Let’s start with independent premises.
