Knowledge is power.
The more you know yourself, the more you understand life.
The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.
To know that we know what we know, and to know that we do not know what we do not know, that is true knowledge.
Real knowledge is to know the extent of one's ignorance.
An investment in knowledge pays the best interest.
He who knows all the answers has not been asked all the questions.
In learning you will teach, and in teaching, you will learn.
Live as if you were to die tomorrow. Learn as if you were to live forever.
The beautiful thing about learning is that no one can take it away from you.
Ignorance, the root and stem of all evil.
The more you know, the more you realize you don't know.
The only true wisdom is in knowing you know nothing.
The greatest obstacle to discovery is not ignorance—it is the illusion of knowledge.
Wisdom is not a product of schooling but of the lifelong attempt to acquire it.
The only source of knowledge is experience.
I cannot teach anybody anything. I can only make them think.
Knowledge comes, but wisdom lingers.
The more you learn, the more places you'll go.
Knowledge is a treasure, but practice is the key to it.
