Where is the Life we have lost in living? Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information?

Ignorance more frequently begets confidence than does knowledge: it is those who know little and not those who know much who so positively assert that this or that problem will never be solved by science.

In a battle all you need to make you fight is a little hot blood and the knowledge that it's more dangerous to lose than to win.

There is one quality which one must possess to win and that is definiteness of purpose the knowledge of what one wants and a burning desire to possess it.

The recipe for perpetual ignorance is: Be satisfied with your opinions and content with your knowledge.

Our treasure lies in the beehive of our knowledge. We are perpetually on the way thither being by nature winged insects and honey gatherers of the mind.

Those who have knowledge don't predict. Those who predict don't have knowledge.

Knowledge cultivates your seeds and does not sow in your seeds.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.

The one exclusive sign of thorough knowledge is the power of teaching.
