Argument Mapper

Build a visual map of an argument by adding nodes for premises, sub-conclusions, and the final conclusion, then connecting them to show what supports what. Useful for any passage where the inferential structure isn't obvious from the prose order.

Used in: Foundations of Logical Reasoning (especially “Arguments and Their Parts”), Fallacies and Errors, Inductive Logic, Abductive Logic. Try a template, or paste a passage you're analyzing into the node text.
