Hi again, Mark-- Isn't it great to feel so passionate about astrology!

I respect what you are trying to achieve more generally, even while differing on the particulars, so here is more feedback.
To get back to your planet-pairings on p. 8, by way of contemplating a possible home for Uranus:
Uranus-Saturn. I agree with the first part of your paragraph 1, but I don't see Tarnas's comment as definitive. I've run through these points in previous posts, but just to summarize: the elemental qualities are not
the decisive factors in current planet-sign rulerships and exaltations. And actually, in following your own lines of reasoning, you apparently do not think so either; although your strongest case seems to rest on elemental qualities.
Venus rules both Taurus and Libra, a cardinal air sign, for example.
Cardinality does not specifically relate to Mars. Jupiter (moderately moist) rules Sagittarius, a fire sign. The exaltations do not fair much better. Mars (hot and dry) is exalted in Capricorn (feminine earth, ruled by cold Saturn.) Saturn actually has two strong air connotations: ruler of Aquarius and exalted in Libra. It has the day triplicity for all of the air signs. So some astrologer in Antiquity thought air and Saturn were a good match.
Tarnas had some super things to say about Uranus, but he was not trying to fit Uranus into traditional astrology. (I have his book after all.) He argued a case for Uranus as bursting out of structures; but actually if we look at Uranus in the context of science, aviation, and space travel-- we don't get anywhere without
structure and innovation ("intellectual catalyst") working in tandem. These activities have both a strong mental and pragmatic component.

As I suggested earlier we don?t need to be monolithic in our view of Uranus. We can take the view it contains the nature of more than one planet. My current position is that Uranus probably partakes in the nature of Mars but also the Sun. However, I am open to the possibility of a Mars-Mercury nature. I am suggesting the first planet listed as the primary influence.
We should then consider (1) whether Uranus brings anything to the zodiac that is unlike its predecessors, and (2) how Mars (or any other planet) operates in a horoscope beyond its elemental attributes. I addressed (1) extensively in one of yesterday's posts. I do not think Uranus overlaps entirely with traditional planets even in combination.
I think your reasoning is that planet-wise, Mars (A) is like (C) Uranus (A=C.) Mars (A) affiliates with (B) Aries (B=A). Therefore Uranus (C) belongs to Aries (B) (B=C). See the difficulty with syllogisms in my previous post.
(2) Let's look at Mars. It rules warriors and athletes. It operates in the horoscope as a kind of raw survival instinct, assertiveness, competitive spirit,or aggression. Mars is often very personal.
Mars is not notably generational/transpersonal. Robert Hand (
Horoscope Symbols, 62-63) makes an interesting point about Mars, that it can be trained by one's mind or the state to operate in a social manner, but this happens only if the individual begins to identify his survival or instinctual aggression with a common cause. In this calculus,
the mind actually bridles raw Mars energy . So we can see Mars getting put to work by the mind in all kinds of ways, many of which are poor fits with Aries. To paraphrase, Mars throws the punch, but the mind creates a scenario in which violence is an understandable reaction.
Mind=air.
To the extent that I take your point about Uranus being like Mars, Hand gives a perfect oportunity to view Uranus as related to the air element, or at least under its authority. (My own syllogism, BTW. Hey, I like it!)
I don't mind Mars-sun not supporting an Aquarius connection, because I don't find this to be a particularly fruitful line of reasoning. As I noted previously, most of the traditional associations of the sun are with authority, kingship, and fathers. Sure, you can find a "creative" component (which sounds more modern than traditional, incidentally) but I do not think this is the primary way the sun is used in traditional astrology practice. Note that if the sun gets too hot and dry (as it can be when the sun is in Leo) the sun acts as a destructive malefic (
Tetrabiblos I:5,) not as a source of creativity. The sun was noted for its constancy in comparison with, say, the moon and Mercury.
Given that I think your argument is really based upon an over-generalized syllogism ("All swans are white") there doesn't seem to be much point in addressing the rest of your non-Uranian two-planet comparisons. See my comments in my previous posts, which I think are more to the point. I wouldn't look to Mars-Saturn to make a case for Aquarius-- I might look to Uranus-Saturn, because it is relevant.
However, just to extrapolate from your comparisions: if Uranus is like Mercury, then Uranus is at home in an air sign. If Uranus actually has commonalities with Saturn (as I argued, despite the preponderance of modern astrologers saying the opposite) then Uranus is at home in Aquarius.
Does anybody seriously associate Leo, Gemini, or Virgo with the "higher mind"? In contrast, we see the opposition of Sagittarius and Jupiter (rules philosophy and higher education, the great benefic) and Gemini, where Jupiter is in detriment. Mercury rules the intellect but it is not the philosopher-king. As an earth sign, Virgo focuses on practical matters.
We also want to clarify where we jump-shift from considering a natal horoscope and cosmology. They have parallels but are not identical.

While you do not seem to accept a Mars association with Uranus(?) you seem to strongly support its connection to Mercury. Correct? While you reject the modern ?higher octave? theory you implicity seem to see Uranus as an agent of intellectual change.
I don't have a problem in seeing commonalities between Mars-Uranus, Mercury-Uranus, Saturn-Uranus, and all sorts of other planet-pairs. I do have a problem in arguing by syllogism when the foundational premises are in doubt. ("All swans are white.")
One can see Uranus as an agent of intellectual change without subscribing to the "higher octave" doctrine. The latter
modern astrology proposition has to stand or fall on its own merits, and I just have not seen it applied successfully in chart interpretations for real people with real problems. Probably I am missing something. If you have, would you kindly send me the references?
I would also appreciate your sending me the reference to the Schmidt doctrine that you mention. I tried googling it but came up short.
Incidentally, Valens (bk 1) didn't think much of Aquarius, but his following key words seem entirely Uranian: celestial, anthropomorphic, free, upward trending, self-willed, godless, uncontrollable.
