## What is pure hypothetical syllogism?

Pure hypothetical syllogisms—**arguments of the form ‘ If p, then q : if q, then r : therefore, if p, then r**‘—have been traditionally regarded as clearly valid. 1 Such arguments are, indeed, valid, if the constituent state- ments are taken to express mere material implications.

## Is hypothetical syllogism a tautology?

Hypothetical syllogism If both implications are true, then the resulting implication is true. Disjunctive syllogism If a disjunction is true, and one proposition is not true, then the other proposition must be true. The table below shows that **it is a tautology**.

## What is the basis of the rule of inference called hypothetical syllogism?

A hypothetical proposition, for Theophrastus is a proposition made up of two or more component propositions (e.g., “p or q,” or “if p then q”), and a hypothetical syllogism is **an inference containing at least one hypothetical proposition as a premise**.

## Is it possible to commit the fallacy of affirming the consequent in a pure hypothetical syllogism?

Is it possible for a single syllogism both to commit the fallacy of affirming the consequent and the fallacy of denying the antecedent? **No, unless the second premise and the conclusion each assert two different propositions**.

## Why is modus tollens valid?

Modus tollens is a valid argument form. **Because the form is deductive and has two premises and a conclusion**, modus tollens is an example of a syllogism. (A syllogism is any deductive argument with two premises and a conclusion.) The Latin phrase ‘modus tollens’, translated literally, means ‘mode of denying’.

## Is modus ponens a syllogism?
