"In liberated moments we know that a new picture of life and duty is already possible; the elements already exist in many minds around you of a doctrine of life that shall transcend any written record we have. The new statement will comprise the skepticism as well as the faiths of society, and out of unbeliefs a creed shall be formed. For skepticisms are not gratuitous or lawless, but are limitations of the affirmative statement, and the new philosophy must take them in and make affirmations out of them, just as much as it must include the oldest beliefs."
