Love is the world's friend, ignorance is the universe's enemy.

Ignorance is the opium of the unenlightened.

Wisdom sees even when her eyes are shut.Ignorance is deaf even when his ears are open.

The narrow path to wisdom is better than the wide road to ignorance.

If you value knowledge, you will hate ignorance.

The road to ignorance is ten thousand times wider than the path to knowledge.

Ignorance is our past. Knowledge is our present. Wisdom is our future.

Wisdom from enemies is better than ignorance from friends.

It is better to suffer for knowledge than to pleasure in ignorance.
