Ladies and Gentlemen:

At the end of the last lecture I gave a rule for positively ascertaining whether or not a graph is alpha-possible. In case it be so, the rule further furnishes a description of the states of the universe to which its possibility is limited. If I had time to set before you the process of reasoning train of thought which determined the formulation of that rule, it would afford an instructive simple example of methodical reasoning. Unfortunately, there is not time for any such illustration in this course, far less can the scientific methodeutic be touched upon, that great third of logic that teaches the principles upon which reasonings are to be arranged into systematic developments
