When we see what some people are dishing out,
we know what Bertrand Russell was talking about:
"The stupid are cocksure, the intelligent full of doubt."
When you meet someone who thinks he's clever,
but seems much too confident in his endeavour,
and talks to you non stop and forever and ever.
When he acts like a prophet defying convention,
never admitting a lack of comprehension,
promptly has a cure for everything you mention.
When he hands out his advice on a silver platter
convincing you that his opinions matter,
you can be certain, he's as mad as a hatter.
There are people trying to convince you that the world is flat.
