Logic and Argumentation

Claims

• A statement or proposition that expresses a belief or opinion
• Typically, the main point or conclusion being argued
• Can be explicit (directly stated) or implicit (implied)

Premises

• Statements or facts that provide evidence or support for a claim
• Can be explicit (directly stated) or implicit (implied)
• Premises should be true, relevant, and sufficient to support the claim

Fallacies

• Errors in reasoning or argumentation that can undermine the validity of an argument
• Types of fallacies:
  • Logical fallacies (e.g., ad hominem, straw man, false dilemma)
  • Informal fallacies (e.g., appeal to authority, appeal to emotion)
  • Cognitive biases (e.g., confirmation bias, anchoring bias)

Counterarguments

• Anticipated opposing views or arguments that challenge the claim
• Acknowledging and addressing counterarguments can strengthen an argument
• Types of counterarguments:
  • Objections to the premises
  • Alternative explanations or claims
  • Counterexamples

Inferences

• Conclusions drawn from one or more premises
• Can be deductive (guaranteed true) or inductive (probable)
• Inferences should be logical and based on the evidence

Evidence

• Data, facts, or observations that support or challenge a claim
• Types of evidence:
  • Empirical (based on observation or experience)
  • Anecdotal (based on personal experience)
  • Expert testimony
  • Statistical data

Reasoning

• The process of drawing inferences and making conclusions based on evidence and premises
• Types of reasoning:
  • Deductive (guaranteed true)
  • Inductive (probable)
  • Abductive (most likely explanation)
• Reasoning should be logical, consistent, and based on the evidence
