Logical Fallacy

A while ago, I was looking up the word “tautology” because I heard it somewhere and didn’t know what it was, which is generally a good reason for looking things up, I think. What I discovered was that tautology is a form of logical fallacy; and further, that there are many different classifications of logical fallacy; and even further than that, that we hear many of these logical fallacies every day! Usually from people whose job is to tell us what to think, luck would have it.
