Ignorance is a cure for nothing.

Ignorance never yet helped anybody.

No one person has the right to withhold knowledge from another. No one is wise enough.

Education is no substitute for intelligence.

Ignorance never settles a question.

Obscurity is never a virtue.

True ignorance is not the absence of knowledge, but the refusal to acquire it.

A man who has the knowledge but lacks the power clearly to express it is no better off than if he never had any ideas at all.

Human ignorance has never needed help.

There's zero correlation between being the best talker and having the best ideas.

There is zero correlation between being the best talker and having the best ideas.

The utmost extent of man's knowledge, is to know that he knows nothing.

No man is the wiser for his learning.

Not ignorance, but ignorance of ignorance is the death of knowledge.
