Why Ari4?

When scholastic thinkers did not call Aristotle 'the Philosopher,' their shorthand for him was A4.  I lengthened this slightly to ari4. 

Aristotle's work was foundational in logic, metaphysics, and for early classification efforts in the sciences.  In politics his definition of the middle class as 'those possessing the goods of this world in moderation' is still useful.  In teaching and education he insisted that a good teacher would put himself out of business by helping his students become so competent that the teacher would no longer be needed!  In that spirit I hope you find many interesting and useful ideas here.
