 A great deal of Abelard’s logical works consisted of discussions of topics, consequences and conditionals. Like Boethius, Abelard thought that true conditionals express necessary connections between the antecedents and the consequents. He argued that inseparability and entailment between the truth of the antecendent and consequent are required for the truth of a conditional. Some twelfth-century masters regarded the principle that the antecedent is not true without the consequent as a sufficient condition for the truth of a conditional and accepted the so-called paradoxes of implication. The question of the nature of conditionals and consequences remained a popular theme in medieval logic (Martin 1987, 2012).
