This is a guided tour of the keyword lexicon I developed while building my personal knowledgebase. I use it to tag the content of quotations taken from a wide variety of sources.  My hope is show how what you already know might be tagged in a way that is mutually advantageous for human and machine learning — that you can see how this lexicon models the singularity of my thought even as it differs from your own. I encourage you to take and modify whatever you find useful or create your own from scratch. Either way, I’m fascinated to see where our metadata deviate and converge.
