Dai Chun-qin · Journal of The Northwest Normal University · 2009
Essentially,categorical syllogism is concerned with such an issue: To draw a conclusion,how are minor term and major term directly connected by link verb,through middle term which is directly connected with minor term by link verb in minor premise,and directly connected with major term by link verb in major premise? Methods of substitution for middle term,which can answer it,are new approaches to categorical syllogism,by which all problems of categorical syllogism can be totally solved,while traditional methods of categorical syllogism,such as method of Venn's diagram,method of rules of categorical syllogism,can partly solve the problems.Thus,Methods of substitution for middle term has transcended over traditional methods of categorical syllogism.
