Osamenor, speaking as someone who spent close to 40 years having to footnote/document most of what I wrote professionally, I find that few astrologers are particular about citing their sources. (Unless they are writing a history of astrology.) This raises some questions in my own mind about "recognizable shared meanings" and "real meanings."
If astrology authors tend to copy earlier sources without attribution, how do we know whether a commonly held belief about a sign (house, planet, &c) is actually correct? Mightn't modern astrology have taken a wrong turn on some delineations, merely because a well-known astrologer wrote something and others decided that it must therefore be true?
Astrology will never be a science precisely because we're not in the habit of rigorously testing our propositions. (When the quantifiers have tried, they couldn't validate astrology's truth-claims.)
A case in point would be the idea of "natural" houses by-the-numbers, where the 4th sign corresponds to Cancer and the moon, the 9th house corresponds to Sagittarius and Jupiter, &c. I own several astrology books where the authors take this so far as to talk about "Venus in Taurus OR the second house," or Uranus in Aquarius OR the 11th house," as though signs and houses were interchangeable.
To me this causes no end of confusion, unless the native actually has Venus in Taurus AND the second house, &c. Signs and houses mean very different things, IMO. Suppose someone has Venus in Taurus in the 9th house. Does this Venus then become "like" Venus in Sagittarius? But what if Sagittarius is actually on the cusp of the 4th house? Does it then become more like Cancer? You see my dilemma.
From natural houses we get the idea of planets "naturally" ruling houses; like the moon naturally ruling the 4th house. For those of us who work with house cusp rulers (lords) based on the actual sign on the house cusp, the idea of another planet "naturally" ruling a house just muddies the water.
A really good book on the problem, and on the evolution of house meanings, is Deborah Houlding, Houses: Temples of the Sky. She points out problems with "natural" houses, such as Venus modernly becoming the ruler of money, a second house matter, due to the match-up of Taurus with the second house. Traditionally Mercury rules money and trade.
A similar example would be converting the 4th house of one's father (in the sense of patrimony) to the mother, because the moon supposedly "naturally" rules the 4th house.
I once tried to find out who first proposed the idea of "natural" houses matching signs by-the-numbers (apart from medical astrology.) Someone thought it was C. E. O. Carter (1887-1968) who wrote several popular books on astrology, plus developing some of his own methods.
Assuming it was either Carter or someone of his generation and stature, "natural" houses might be an example of "recognizable shared meanings" being highly problematic, yet widely adopted by his fans. Some decades later, nobody much remembers who came up with the idea, it just seems like the "real" astrology.
If they seem to work anyway, what does this say about astrology? Are we simply working through some kind of confirmation bias (Barnum effect)?
There are other examples of this nature, where "follow the leader" seems to be a guiding principle of astrologers today, whether or not there is sound reasoning behind it.
