What is ignorance?

I now understand the meaning "ignorance is bliss". Ignorance can be a learning process to knowledge. Knowledge has variables of truth opinion and lies that are believed with facts and distorted facts believed. But ignorance is bliss after one acknowledges ignorance is bliss. How does a mental retarded child understand his/her emotions if no one teaches them to understand them? The word retarded means (slow) below normal. Medically there is (no normal)!

What's normal is normal for you not me. A measuring stick measures. Words cannot be measured but only defined. Ignorance is like the word truth only opinion counts because one can be wrong. Overcoming ignorance with knowledge is commendable. How to use that knowledge is understanding and wisdom. Thoughts please. pljames
