Can someone tell me why propositional logic is important and why Aristotelians and the Stoics spent so much time on it?

I have started reading Anthony Kenny’s A new History Of Western Philosophy, and am still getting the grasp of philosophy itself, and some of the disciplines of it I do not understand why it is important and why we would need to conclude an answer for it, such as propositional logic and what use it would be to know it. 

Also, it seems that some disciplines are so ambiguous that after thousands of years have not come to a conclusion, so why argue on a topic that will never have a complete and definitive answer?

The use of logic is that it is the art of making inferences well. The use of making inferences well is that they only accomplish their function when they are made well, whereas the impair their function when made poorly. The use of inferences is that they're one of the basic elements of thinking. And the use of thinking is to understand and communicate about the world.
