Knowledge is the life of the mind.

Knowledge is the eye of desire and can become the pilot of the soul.

When a man's knowledge is not in order, the more of it he has the greater will be his confusion.

I think we risk becoming the best informed society that has ever died of ignorance.

To acquire knowledge, one must study but to acquire wisdom, one must observe.

Any knowledge that doesn't lead to new questions quickly dies out: it fails to maintain the temperature required for sustaining life.

The ability to perceive or think differently is more important than the knowledge gained.

Knowledge is not a passion from without the mind, but an active exertion of the inward strength, vigor and power of the mind, displaying itself from within.

I'm hungry for knowledge. The whole thing is to learn every day, to get brighter and brighter. That's what this world is about. You look at someone like Gandhi, and he glowed. Martin Luther King glowed. Muhammad Ali glows. I think that's from being bright all the time, and trying to be brighter.

Never stop learning knowledge doubles every fourteen months.
