The way people argue on social media is so often so mindless that I decided to go back and review the rules of logic. I took down Introduction to Logic by Irving Copi and Carl Cohen from a shelf in my home library to check out the fallacies. Originally published in 1994, it's a college textbook. Interestingly Part One on reasoning begins with the quote in the headline from Isaiah, "Come now, and let us reason together." Even before I had a chance to dive into the subject of logic, I was intrigued and distracted by the quote and decided to look it up and check out the context.
Bible translations vary greatly and there are a number of different translations for this particular verse. I checked them out at Bible Hub which I often use as a reference. Most of the bibles listed use the words "reason together." I'll just list one example:
English Standard Version: “Come now, let us reason together, says the LORD: though your sins are like scarlet, they shall be as white as snow; though they are red like crimson, they shall become like wool.
