Ignorance is a menace to peace.

In the clashes between ignorance and intelligence, ignorance is generally the aggressor.

Where ignorance is our master, there is no possibility of real peace.

When an individual, a sect, a clique or a nation hates and despises another individual, sect, clique or nation, he or they simply do not know the objects of their hatred. Ignorance is at the bottom of it.

Ignorance per se is not nearly as dangerous as ignorance of ignorance.

Communism is a hateful thing, and a menace to peace and organized government.
