The more I study nature, the more I am amazed at the power of the Creator.

The world is a great game, and we are all players in it.

The great lesson of science is to believe nothing without proof.

The great tragedy of life is not that it ends, but that it is so short.

The great end of education is to train the mind to think.

The great end of all human effort is to make the world a better place.

The great end of all human knowledge is to understand the universe.
