Denying the consequent (Arguing carefully)

North Vancouver, last evening

From Blackburn it is valid that the antecedent is prior to the consequent in philosophy and logic. It is stated that

p = Antecedent
q = Consequent

It is argued:

p The leg is broken
q The leg will hurt

The inference is...

-q The leg does not hurt
-p The leg is not broken

This is logical.

Logic. If a conditional statement is accepted as true then the negative can be inferred as well. Also called modus tollens...

Denying the consequent is where the negative aspect is also true.

This is logical.
Blackburn page 99.

However, in contrast.

The leg is broken

The leg is comfortable

(The leg is under the influence of narcotics)

This is logical.

Again we analyze the logical and the reasonable.
