I do not pretend that I know the whole solution of the world's problems, but I am burdened with a Puritanical sense of obligation to set the world to rights. I feel responsible for many enterprises that are not really my business at all, but many times I have kept silence on issues that interested me deeply through the fear that others would be blamed for my opinions. I have never been willing to believe that human nature cannot be changed; but even if it cannot, I am sure it can be curbed and led into channels of usefulness. I believe that life, not wealth, is the aim of existence — life including all its attributes of love, happiness, and joyful labour. I believe war is the inevitable fruit of our economic system, but even if I am wrong I believe that truth can lose nothing by agitation but may gain all.
Helen Keller
