There is only one good, knowledge, and one evil, ignorance.

The more I see, the less I know for sure.

A journey of a thousand miles begins with a single step.

Where there is shouting, there is no true knowledge.

Death may be the greatest of all human blessings.

The most important knowledge is that which guides the way you lead your life.

I cannot teach anybody anything. I can only make them think.

Strong minds discuss ideas, average minds discuss events, weak minds discuss people

Always go too far, because that's where you'll find the truth.
