Patriotism is voluntary. It is a feeling of loyalty and allegiance that is the result of knowledge and belief. A patriot shows their their patriotism through their actions, by their choice.

You can do anything you think you can. This knowledge is literally the gift of the gods, for through it you can solve every human problem. It should make of you an incurable optimist. It is the open door.

You can acquire a lot of knowledge without ever going to school.

We don't focus as much in schools on educational knowledge which requires thinking and application, as we do on acquiring facts.

There can be no knowledge without emotion. We may be aware of a truth, yet until we have felt its force, it is not ours. To the cognition of the brain must be added the experience of the soul.

It is not the quantity but the quality of knowledge which determines the mind's dignity.
