Better to know a few things which are good and necessary than many things which are useless and mediocre.

Leo Tolstoy

Great spirits have always encountered violent opposition from mediocre minds.

What is important is not the quantity of your knowledge but its quality. You can know many things without knowing the most important.

Life consists in penetrating the unknown, and fashioning our actions in accord with the new knowledge thus acquired.

The most important knowledge is that which guides the way you lead your life.

The only absolute knowledge attainable by man is that life is meaningless.

He who has access to the fountain does not go to the water-pot.
