Tutorial 4 - Multi-Layer Arguments
No doubt you're already aware that there is another dimension in which arguments can become more complicated.  As well as having many reasons or objections bearing upon a single contention, we can have many layers of argument: reasons backing up reasons, objections to reasons and so on. 

Tutorial 4 covers the basics of multi-layer arguments, including what they are and how to map them.  We look at

  • the four fundamental kinds of two-layer arguments
  • arguments with more than two layers
  • complex arguments which are multi-layer and multi-reason
  • two common mistakes in mapping multi-layer arguments
