It is not going upward or downward, it is going in a circle. But we are accustomed to say of everything that it is either going upward or downward. We may agree with those who say that we are going upward, or we may agree with those who hold that we are going downward, but in reality progress does not mean continually going upward; progress means going upward and downward at the same time; progress should be described by a circle and not by a straight Line. If we look at it from this point of view, everything in the world has a circular aspect, for the real picture of motion, of movement, is a circle.
