LessonsExceptive Syllogism: Valid Inferences from Connected and Disjunctive ConditionalsQuiz

In the conditional “If A, then B”, A is the antecedent and B the consequent. The relationship says that if the conditional is true and A occurs, B must follow.

Antecedent: what is supposed, for example sunrise.
Consequent: what follows, for example the presence of daytime.

Knowing that “if A, then B” is true does not by itself establish that A or B has occurred. A separate exceptive premise is needed.
