Syllogistic Tense Logic

Show Summary Details


The term ‘syllogism’ was used in a wide sense to signify any piece of reasoning, theoretical or practical. Within the area of theoretical reasoning, a distinction was drawn between categorical and molecular syllogisms. A molecular syllogism is distinguished by the presence of at least one molecular proposition occurring as a premiss. In a categorical syllogism, on the other hand, each proposition, whether premiss or conclusion, is categorical. Aristotle expounded on a theory of syllogism that was taken up by medieval logicians and extended in a variety of directions. This chapter focuses on elementary syllogistic and syllogistic tense logic and addresses the question of whether there can be valid syllogisms containing non-present-tensed premisses.
