Ancient Greek, Logic and Reason Reason is a tool to describe, and an ability to perceive descriptions of, cause-effect relationships.
Logic is a tool in language that describes rules of relationships between numbers, sets, and objects (people included, as much as immaterial or phantasy objects) that are true at any time, anywhere, in any possible, or imagined world.
Reason is an ability that manifests in each person to different measures. Logic applies to all person's thinking equally. To absorb logic properly, one must have a reasoning ability to a certain minimum limit. You can tell a ten-year old child that 5 + 7 is the same as 7 + 5, and he will believe you, but you can't tell the same to even an intelligent animal, like a dog, because the dog's reasoning ability has not hit that lower minimum required limit to absorb the logic.
Some people make errrors in reason, yet they can't be shown their own errors, due to their limitations in their ability to reason.

That said, many arguments (or all) among people start not because the topics are diverse, with many possible resolutions, but because the people who argue have different limitations to their ability to reason. Even very, very intelligent people can have limitations to their ability to reason, for instance, if they are obsessed or believe a religious dogma that stands in the way of their ability ot accept reason that leads to the contrary solution or resolution to their accepted one which had been dictated to them by their religious dogma.

People on this website hate me for being an atheist and decrying religion. They went as far as telling me in public spaces and in private email that I am a fucking asshole.
I don't hate religion. I hate inability to reason.
Those who are not able to reason well, due to mental (intellectual) limitations, I don't condemn. I feel pity for them.
Those who are not able to reason well due to the limitations of their religion, I show them precisely where they make a mistake in reasoning. They hate me for that. They can't stand the fact that their own world view, their very philosophy is being threatened by unassailable reason and logic.
I normally abandon all arguments sooner or later, after I have had my say. I abandon the arguments becasue 1. I don't think I can change anyone's thinking, values, or ability to think and 2. They can't change mine.
If I am found in the wrong, in terms of logic, insight, facts, or reason, I capitulate. I do admit I was wrong. There are many instances on this website of my having done so, so I am not simply or falsely boasting.
