These flashcards cover key concepts and vocabulary regarding deductive arguments, logical reasoning, and categorical syllogisms.

Deductive Argumentation

A form of reasoning where the conclusion necessarily follows from the premises.

Conditional Proposition

Sufficient Condition

Metabolism

The set of life-sustaining chemical reactions in organisms, necessary for something to be classified as living.

Negation

Symbolized with '~', it indicates the opposite truth value of a statement.

Modus Ponens (MP)

A rule of inference that states if 'P → Q' is true and P is true, then Q must also be true.

Modus Tollens (MT)

A rule of inference stating that if 'P → Q' is true and Q is false, then P must also be false.

Categorical Syllogism

A form of deductive reasoning that consists of two premises and a conclusion, where the premises contain a term common to both.

Middle Term

The term that appears in both premises of a syllogism but is not in the conclusion.

E Claim

A universal negative statement declaring that no members of one category belong to another.

I Claim

A particular affirmative statement indicating that some members of a category belong to another category.

O Claim

A particular negative statement stating that some members of one category do not belong to another.

Hypothetical Syllogism (HS)

A rule of inference that allows the conclusion of a syllogism based on two conditional premises.

Disjunctive Syllogism (DS)

A form of reasoning that concludes one term from the negation of another, based on disjunction.

Sound Argument
