Argument structures (7)
Standard form, deductive argument, inductive argument, generalisations, analogies, general principles and causal reasoning
Standard argument form
3 reasons under each other, conclusion on the bottom
Deductive argument
valid or invalid, true premises=true conclusion, Are the premises true? Is the form of the argument valid?
Inductive argument
Conclusion doesn’t follow premises, are the premises true or acceptable? Are the premises relevant to the issue at hand? Are the premises compelling enough to justify conclusion?
Generalisations
involve making a general claim based on limited/specific evidence
Analogies
Drawing conclusions about one situation based on another
General principles
apply general principles to a specific case, opposite to generalisations
Causal reasoning
Offer an argument that one thing led to another thing happening
How do you analyse an argument
Determine if it is valid (logical), sound (true with a logical conclusion), cogent (convincing)
Modus ponens
affirms, If A then B, A therefore B
Modus tollens
Denies, If A then B, Not B, therefore not A
Fallacies (6)
Ad hominem, appeal to irrelevant authority, genetic fallacy, hasty generalisation, argument from ignorance, equivocation
