We cannot rely on supernatural intervention into our problem-solving processes. We have no system of dependence on rigid dogmas to govern the events of our daily lives. The theist relies on a set of specific rules of conduct on a daily basis. Such a person is dependent upon those rules to function normally. An Atheist can function normally in society without reference to any arbitrary set of rules for his conduct.
Atheists are content with their life-style.
Atheists are comfortable and content with a life-style free from theism. We know that one is born within a circle of freedom. The size of that circle is directly proportional to the number of freedoms one enjoys. It is the duty of each of us to see to it that during our lifetime that circle of freedom is never decreased, that it either remains the same size or is enlarged. We know that if we allow it to decrease that the following generation will have a smaller circle with which to start.
