A post by Bogus Magus at the Maybe Logic blog notes that G. Spencer-Brown, author of The Laws of Form, has turned 90. The post reminds us that Robert Anton Wilson's Schroedinger's Cat trilogy frequently quotes Brown's book.
The Laws of Form is philosophy and mathematics, but is it alchemy? A paper, "An Esoteric Guide to Spencer-Brown's Laws of Form," asserts that, "the work can also be read with an esotericeye, which is to say, with a sensitivity to the form and nature of spiritual experiences." He adds, "What I would like to do in this commentary is show that within the LoF are a number of coherentrelations to principles that are rightly considered esoteric: they are hidden, but very important whenconsidering actual spiritual development. Of course as a whole LoF can be taken as a cosmologicaltreatise, and in this sense could be read alongside works such as those by Ibn Arabi, Nagarjuna, LaoTzu, or Eckhart, among many others." The paper is here, and I thank Arthur Hlavaty for pointing it out to me.
