God lets everything happen for a reason. It's all a learning process, and you have to go from one level to another.

Never stop learning; knowledge doubles every fourteen months.

Real knowledge is to know the extent of one's ignorance.

Try to learn something about everything and everything about something.

Knowledge is the prime need of the hour.

The beginning of knowledge is the discovery of something we do not understand.

Every addition to true knowledge is an addition to human power.

To know, is to know that you know nothing. That is the meaning of true knowledge.

You cannot escape tomorrow's responsibility by evading it today.

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