You can only manage to convince a person to admit to being wrong, not ignorant, arrogant, or stupid.

Not every person that speaks less than you do is more ignorant than you are.

The most ignorant of all people is a person who is self assured in his or her premature decisions.

It sometimes requires ignorance and arrogance to know something for sure.

An ignorant man who is regarded as knowledgeable by people who are more ignorant than him is still ignorant.

It is a sign of arrogance to be mad at someone for not acting as per your advice, especially if it was unsolicited.
