摘要
The definition of truth expressions of hypothetical propositions according to the truth tables does not conform to the intuitive sense of hypothetical propositions. What is described by a truth table is the truthfunctional relation between a truth expression and the propositional variables that consist in the truth expression, but what is reflected by a hypothetical proposition is the interactive relation about truth and falsity between the subpropositions. Someone, who does not comprehend correctly the truth tables, tries to deny the opinion that the truth tables do not conform to the intuitive sense of hypothetical propositions. But the effort is in vain.
