In Alistair's post (I believe) Russell is quoted as:

which reminds me of the astrology I used in my 20s as a young aspiring
natural sciences student. As I rationalized astrology to fit this old-time
wisdom into my 'modern' sci. vues.
The horoscope is a composition of ASPECTS in a metaphoric representation of
the known - knowable status of the ambient part of the universe (Solar
system) at BIRTH MOMENT, with differences of as little as 2-3 minutes
(angle-changes). It was a HINT for the understanding mind and included the
rudimentary knowledge of close sequencing movements of the points included.
All that (white rabbit problem?) is expressable in a metaphric simulative
translation (which may be wrong). This was in the 1st half of the 40s.
I did not use astrology ever since, but then it was interesting.
No conclusions for the ongoing topics.
