Argument Diagram
An argument diagram is a visual map of how the premises of an Argument support its Conclusion.
Complementary view
Same content as standard form, different view.
Four support patterns:
- Convergent: multiple premises each independently support the conclusion; removing one weakens but doesn’t destroy the argument
- Linked: premises only work together; remove any one and the argument collapses (e.g., both premises of Modus Ponens)
- Divergent: one premise supports multiple conclusions
- Sequential: chain of premises → sub-conclusion → final conclusion (see Sub-conclusion)
Counter-considerations and rebuttals:
- Counter-consideration: a point against your own conclusion that you acknowledge
- Rebuttal: your reply to the counter-consideration
Good practice
Acknowledging counter-considerations honestly is part of Critical Thinking; it shows you’ve engaged the strongest version of the opposing view (the Principle of Charity)
