ANNOUNCEMENT
The quality popularly designated as "Common Sense" comprehends, according to the modern point of view, the sound judgment of mankind when reflecting upon problems of truth and conduct without bias from logical subtleties or selfish interests. It is one of Nature's priceless gifts; an income in itself, it is as valuable as its application is rare.
