If you cannot compare, how can you define something?

"All humans are HOMO SAPIENS: humans are EXEMPT from the fundamental rules of BIOLOGY."
"Jewish people are the most intelligent. They win almost 40% of the Nobel Prize's and they have a small population of only 14 million."

Everybody is entitled to his own view.
I had a friend who insisted that men are superior to women. "In History you find very few famous women.
Most Geniuses are men"
He forgot for centuries women were denied culture and education.
A woman's place was in the kitchen (and when necessary in bed).
I think there are women who are smarter than certain men and men who are smarter than certain women, just like Jewish who are smarter than other races and vice versa.
I also think a person is made by his genetics and also by his environment.
If you are richer you certainly have more chances to be more educated, but not necessarily rich means educated or intelligent.
God ( or whoever you believe in) made people white, black, red and yellow.
Smart, stupid, ugly and beautiful.
The intelligent people wouldn't be intelligent if there were not stupid’s, just like the beautiful.
Beauty exists because there are ugly things.
If all was the same, being intelligent would just mean being normal.
There is no limit to stupidity just as there is no limit to intelligence.
But one exists because there is the other.
