When you are with people who have authority, don’t try to impress them and pretend to be important. It would be better recognition for you to be asked to take a higher place than to be told to give your place to someone more important.
Half the harm that is done in this world is due to people who want to feel important. They don’t mean to do harm–but the harm does not interest them. Or they do not see it; or they justify it because they are absorbed in the endless struggle to think well of themselves. – TS Eliot
Don’t be too quick to take someone to task based on what you have seen or heard. If another person later proves you wrong, what will you do then?
It is important to realize two things about fallacies: first, fallacious arguments are very, very common and can be quite persuasive, at least to the casual reader or listener. You can find dozens of examples of fallacious reasoning in newspapers, advertisements, and other sources. Second, it is sometimes hard to check whether an argument is fallacious. An argument might be very weak, somewhat weak, somewhat strong, or very strong. An argument that has several stages or parts might have some strong sections and some weak ones. The goal then, is not how to label arguments as fallacious or fallacy-free, but to help look critically at your own arguments and move them away from the “weak” and toward the “strong” end of the continuum.
