Here are some proverbs on fools or those lacking intelligence. It should be noted that intelligence does not necessarily mean having a command over a particular domain of knowledge, rather it is the lack of understanding that one never has complete command over a particular domain of knowledge or all domains that makes one a fool. Therefore one should seek knowledge and apply it, constantly.
"When the fool is told a proverb, it has to be explained to him."
"It is the fool's sheep that break loose twice."
"By the time the fool has learned the game, the players have dispersed."
Shemhotep ************ "There is something dreadfully wrong with an education/socialization process that leaves us ignorant of our past, strangers to our people, apes of our oppressors, and creatures of habitual, shallow thought, and trivial values." -Dr. Asa G. Hilliard,III
"general group behavior patterns matter more than individual exceptions. and past group behavior is indicative of future group behavior." - yuckwheat
"Everyone has their myths which is fine. However when one parades "myth" as "fact" especially concerning ANOTHER group of people independent of the said myth-making group then we have a problem. The myth now becomes a LIE." - Solarus
