Argument Forms and Fallacies
- Modus Ponens is a mode of affirmation, affirming the antecedent (if P, then Q; P, therefore Q)
- Modus Tollens is a mode of negation, negating the consequent (if P, then Q; not Q, therefore not P)
- Fallacy of Affirming the Consequent is linked to invalid arguments; true premises lead to a false conclusion, where the consequent is affirmed (if P, then Q; Q, therefore P).
- Fallacy of Denying the Antecedent is linked to invalid arguments; true premises lead to a false conclusion, where the antecedent is denied (if P, then Q; not P, therefore not Q)
- Fallacies are arguments that seem sound but have structural flaws in their logic.
- Formal Fallacies are those in which errors exist in the form or structure of the argumentation rather than its content.
- Informal Fallacies are those that may have a valid structure but flawed reasoning, and are less apparent in their fallacious nature.
- Fallacy are arguments that seem sound but have structural flaws in their logic.
