I've been trying to memorize the 12 Virtues of Rationality recently.  I've been using spaced repetition to memorize each virtue, but I was struggling to keep them in sequence, and to think of them in whole, rather than 12 separate elements.

To aid the process, I developed the following mnemonic with the aid of Claude Sonnet 4.  It includes jargon from one of my favorite hobbies (rock climbing), so it probably doesn't work well for a general audience.  Nevertheless, I'm putting it out there in case anyone else might find value in it.
