He was ridiculed by DJ's cohort for these writings. He gets a bit sloppy towards the end, but the key points are there for those who know how to use them.
It would make sense that DJ might have scorned CC's attempt to legitimize himself in the academic world. (On the other hand, thinking aloud, wasn't DJ's intent with CC that CC pass on the knowledge?)
I remember years ago seeing discussion/contemplation that CC dictated this treatise to the Witches, who basically took it over. But back in the 70's, the connection of CC's writings to Husserl was noted in academia. I remember my Theories of Consciousness teacher discussing it.
