Ah, ignorance. The word is typically associated with the term "ignorance is bliss", or in other words, being completely unaware of one's surroundings makes one happiest. It seems to apply well in this day and age, considering the amount of violence and disgusting human behavior that takes place in our world. Something about the word "ignorant" (or other forms of the word) disgusts me, because people just don't know how the hell to use it.

Here's how it's presented in the dictionary:

ig·no·rant (gnr-nt)adj.
1. Lacking education or knowledge.
2. Showing or arising from a lack of education or knowledge: an ignorant mistake.
3. Unaware or uninformed.

OK, simple enough. It obviously fits well into the timeless cliche, and seems like a word that can't be abused.

Makes you seem more sophisticated?
