Think like a builder first
Meet the cast — the characters who teach this
-
Posit Claim — asserting-for-testing posture (claim is a card on the table, not a fortress) -
Heft Evidence — weighing-with-care posture (weight matters more than count) -
Lean Warrant — connective-reasoning posture (the BECAUSE between evidence + claim) -
Counter Counterargument — opponent-taking-seriously posture (best version of the other side strengthens yours) -
Pry Fallacy — trap-spotting posture (check YOUR argument first; 18-fallacy catalogue) -
Gloss Definitions — agree on what the key words mean first; many fights are really about words; owl with a little dictionary -
Footing Hidden assumptions — surface the unstated ground an argument stands on and check if it holds; mole checking the floor -
Temper Qualifiers / scope — match a claim's strength to its evidence; 'usually' survives what 'always' can't; badger with balance-scales -
Onus Burden of proof — whoever makes the claim supports it; bigger claims need bigger evidence; heron balancing the scales -
Grant Concession / common ground — grant the true points, find the shared ground, argue the real slice; deer in a shared clearing
