# I What is a convergent argument?

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?

As far as I know, "convergent argument" is not a term that is precisely defined in mathematical logic. It sounds like terminology from the old-fashioned field of "Rhetoric".

ah ok...I would like to clarify that I am studying schaums outlines of Logic (logic in general) and it shows up in the first chapter. But not in the book Logic for dummies..so you may be right!

It looks like the term "convergent logic" simply refers to a combination of basic independent statements joined by "and". So it is a simple narrowing down of the options to the final conclusion. I am not familiar enough with the terminology of logic to state it more formally, but I'm sure that it can be done.
