I try to get rid of people who always confidently answer questions about which they don't have any real knowledge.
Certitude is not the test of certainty. We have been cocksure of many things that are not so
Belief in the absence of illusions is itself an illusion.
The minute you think, 'I have done it' or 'I know what is happening,' you will start to go down.
It's only because of their stupidity that they're able to be so sure of themselves.
That idea of being so sure of what has happened, and what will happen, is the most idiotic human thing that anyone can do.
Once you get it into your head that somebody is controlling events, you can interpret everything in that light and find no reasonable certainty anywhere.
