I looked at a pmemory document someone sent me years ago. I don’t know how much of the course it covered or how essential it was to the program. If memory serves, they had certainly interpreted some aspects of Bruno in what I looked at.
However, Bruno is interpretable and I feel that it’s a bit misguided to think that he was offering a “system.” This is not always that clear in Bruno, but is much clearer in the books by his purportedly most close student, Alexander Dicsone. At least in my reading of Discone, there’s a mixture of astonishment and mockery of students who don’t “get” that you’re not supposed to copy/paste Bruno’s descriptions or process.
Bruno himself has an edgy tone here and there, and he basically says as a kind of Zen challenge to wake one up to the personal nature of using the tools that “if you think there’s a better way, go ahead and show me.” It’s like Dark Yoda, given how much proto-information science Bruno has in his writings (especially in On the Composition of Images.
But he’s also gentler in places and explains that paraconsistent nature of mnemonics which are guided by the nature/“evolutionary” pressures language itself places upon their functioning. In another Zen-like challenge, he says that anyone who thinks as long as hard about it as he has well come to the exact same conclusions. This is proto-science at its finest and one of the reasons we remember him, not just in memory, but also astronomy. He certainly had errors, but scientific thinking and intellectual charity in the face of evidence wasn’t one of them.
Anyhow, Dicsone is just as funny as Bruno, but not quite so Zen or charitable. I’m not entirely sure how it is evidenced that he was Bruno’s direct student, but that’s what some texts say. In any case, it seems to me that Dicsone understood Bruno more than most, but there’s polysemy enough for use to make many Bruno’s.
In fact, when I spoke with Bruno translator John Michael Greer, and asked him about how I might avoid creating my own Bruno in the way that others have (i.e. an objective take), he simply said, “You can’t.” I’m still trying though and it is a huge challenge due to the wide corridors of polysemy his combined mnemonic texts create.
