Argument

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)
