Abstract
It is a common, even a commonplace, observation that the world in general is hostile to new ideas. And yet without them there can be no social progress. Material advancement is dependent upon the extension of man's reign over nature; moral or spiritual growth, upon his control over himself. Both alike require thought. Thought, therefore, should be free. Ideas are the one commodity that should be freely produced and freely exchanged. And yet thought is not free, and will not be until man is greatly changed. In every age free and independent thinking has been discouraged.
