"Without deductive logic science would be entirely useless. It is merely a barren game to ascend from the particular to the general, unless afterwards we can reverse the process and descend from the general to the particular, ascending and descending like angels on Jacob's ladder."

In ascending order the qualities of Patriotism are: 1. To work, fight, or die for your own survival. 2. To work, fight, or die for your immediate family. 3. To work, fight, or die for a group, extended family, tribe, or clan. 4. To work, fight, or die for a group too large for all the individuals to know each other. 5. To work, fight, or die for a way of life.
