Helen Keller — "Security is mostly a superstition. It does not exist in nature."

"The future is a world of possibilities."

"Science may have found a cure for most evils; but it has found no remedy for the worst of them all — the apathy of human beings."

"The test of a first-rate intelligence is the ability to hold two opposed ideas in mind at the same time and still retain the ability to function."

"Optimism is the faith that leads to achievement. Nothing can be done without hope and confidence."

"I believe that all through the ages there have been men and women who have been deaf and blind, who have had magnificent souls and who have lived lives of quiet heroism."
