This reminds me of my Real Analysis class: where I took too drawing Venn
diagrams on butcher paper to keep track of the subordinations and
properties. A case where you wished the number of Theorems outnumbered
the number of Definitions:) It did help me to keep the structures in
mind and I see no reason it couldn't be mathematically useful.
Quote from the "Lessons of History" by Will and Ariel Durant--1968
… In England and the United States, in Denmark, Norway, and Sweden,
in Switzerland and Canada, democracy is today sounder than ever before.
… If race or class war divides us into hostile camps,
changing political argument into blind hate, one side or the other
may overturn the hustings with the rule of the sword.
If our economy of freedom fails to distribute wealth
as ably as it has created it, the road to dictatorship will be
open to any man who can persuasively promise security to all;
and a martial government, under whatever charming phrases,
will engulf the democratic world.
