Is it any argument structure not classified as a syllogism? where premises lead to conclusions which is another premise. It seems that the definition is that in a convergent argument all the premises are independent of each other and support the conclusion only. But how does one know? "I think I should buy this used Toyota Corolla. It is in good shape, it gets good mileage, and besides, it is within my budget." the website here: https://pegasus.cc.ucf.edu/~janzb/courses/hum2020/argumentstructures1.htm says that the above statement is convergent. How can it be modified to become non convergent?
