Of course, it isn't only reasons that contain hidden assumptions.  Here's an objection for you to work with.

Exercise 5

1. Create an Analysis map that shows the hidden premise in this argument:

One might conclude that Macbeth was evil, however he was respected by others.

Drag and drop sections of the above text onto the workspace to proceed.  This works with any version of Rationale.

Hints

• Drag the relevant portions of the text onto the workspace to make claim boxes

• Remember to refine the claims according to the rules you learnt back in set 4

• You have two choices:
  • Either connect the boxes first, then select 'Analysis' in the 'Change' section of the ribbon pane, then use the 'Box' button to turn the automatically generated reason into an objection
  • Or use the 'Box' button to turn the main claim red to show it is an objection, then use the 'Analysis' button to turn it into an analysis box, then connect up your map.

• Add a new claim box to show the hidden assumption: make sure you drag this into the existing objection area

• Work out what belongs in this new claim box by looking for key words that appear in the position and the main claim, but not in both

2. Check your work against the model.
