“Man know thy self and thou shalt know the universe and its gods.”

Ignorance has the word ignore inside of it.

As we look at the etymology, it begins with the letter “I” and then “gno”. That “gno” comes from ancient roots and has relatives in many ancient languages.

In particular we look at Greek. That “gno” has to do with knowledge.

Sometimes that “g” could be a “k” in the same way that we say “to know.”

That “kno” is the same as the “gno”, to know.

“Diagnosis” is to examine to acquire knowledge.

That “gno” in diagnosis is the same root component.

That “gno” in English is the equivalent of “jna” in Sanskrit. That “jna” means to know. It doesn’t mean to know with the intellect. It means to know through perception. The Greek “gno” also means to know through perception, to know from experience.

Knowledge:
from Old English cnawlece “acknowledgment of a superior, honor, worship;”

which is from cnawan “to perceive”

related to Sanskrit jna

When we say “to ignore,” that “I” in the beginning means “to lack, to not have.”

So really, the word ignore means “to lack perception.”
