"How Many Astrological Methods Do We Need?"
That's a great, thought-provoking question!
Rather than (immediately) philosophize, let's examine it empirically. If we look out at the Astrologers that come to the Forum and post and if we look at the literature in the field, it seems that the answer must surely be INFINITY.
Thinking about it, perhaps that is what Astrologers seem to WANT. What they NEED is perhaps a different question altogether.
My only real fear in this approach to the question is that I think of SuperCuts (a hair "salon" in the States). I don't know if it is still this way (I live in Germany for years now), but when one got a haircut, the time was noted and the "manager" would occasionally come back and let the "stylist" know how much time was LEFT. In short, your haircut wasn't finished by quality or progress of the haircut, it was determined by when your time was up. Since, in Astrology, we are often an ORACLE to the client, we have to do what helps most regardless of the time involved.
Now, in Astrology, we see some astrologers (won't mention any names) that use hundreds of asteroids and look at "the future" with more than a half-dozen specific techniques. On the other hand, we have someone like Noel Tyl, who uses (mostly) transits and solar arcs, with a nod for the progressed Moon. (I have a sneaking suspicion that the correct answer is somewhere BETWEEN those two extremes, BUT LEANING TOWARDS THE LATTER, not in particular technique, but in NUMBER.)
From a "service" oriented perspective, we only need the techniques that are NECESSARY to give the service that the client wants. Part of the problem is that we are all fighting against negative P.R. (and let's say general misunderstanding of what Astrology IS). Because of this, we have a strong drive to be "righter than right", which can lead us quite easily into chasing every leaf that blows in the wind. (in terms of techniques)
I know that, no matter how satisfied *I* am with a particular technique, there is always the urge to learn more and to examine more possibilities. I think this is healthy as long as we don't get LOST IN THE SEARCH or take too strong of a "hit" in terms of how many people we can ultimately "help".
The bottom line is to use Astrology to IMPROVE THE HUMAN CONDITION. (hope we can agree on that broad definition) We must be watchful of things that might deter us from that.
Now, Unique_Astrology has mentioned the importance of having an accurate birthtime and though I am hesitant to use the "rectfication" word in recent days on this Forum (there is absolute disagreement from MANY about *HOW* to go about doing this in the best way); still, I feel that Unique_Astrology is entirely correct. There is a question of PRECISION, which is necessitated based on TECHNIQUE. If one only uses transits and solar arcs, a birthtime to the minute is basically enough. (in solar arcs, one minute accuracy is 15' of arc on the Midheaven, or of course, 3 MONTHS time) I won't tangent onto the idea that, in 3 months, so many different things can happen that it stretches reliability to try and "define" a 3 month period, when so many varied things can happen in that amount of time. (Generally) if we're talking about Primary Directions, then a birthtime to the minute is an unfinished rectification...it's not usable. (This is because a SLIGHT change in birthtime leads to a LARGE change in timing) [Now, of course, the HINT is in that last sentence about HOW we should go about rectifying, but I'll leave that as a pointing finger, rather than a "do it this way!" comment.]
Unique_Astrology HAS presented a method and I personally have not looked into it yet, so I can't critique or even "review" it. It does appear to be math-heavy, which I think would likely scare away MANY in these days of computerized, instant presentation of information.
The problem, or one way to be sure and get side-tracked in obtaining a super-accurate birthtime is to allow the subjective mind of the astrologer too large a sway in the process. The best way, ie. the objective way, would be to have a system of NEVER-CHANGING, DEFINED symbolism. One has to use tight orbs, so that the time period is brief enough that it has MEANING when an event occurs in that time. (This previous point is IMPORTANT. On another website, a psychologically oriented one, again, won't mention any names, there is an astrologer putting forth rectifications and basing them often on Solar Arc activity with a WHOLE DEGREE range of applicability, ie. one year. It should be obvious that any of us can find SOMETHING that occurs in our life relative to the astrological aspect, IF WE ARE ALLOWED A WHOLE YEAR OF TIME IN WHICH TO SEARCH. If a certain solar arc occured in July 2005, then we are talking about BASICALLY THE WHOLE OF 2005 as the period of its applicability according to that particular astrologer's approach. So, in that year, if the solar arc related to a possible accident, then do I see my fender bender in May or my fall down the stairs in August or both? If the solar arc seems to suggest a death in the family, are we thinking of Uncle John dying in March or Aunt Betty dying in November, or both? What about the years where I had two accidents and NO attending solar arcs to "blame" it on? It should be obvious that the larger time period that we "envelope" into having relevance, the LESS precise we CAN be.)
Now, Unique_Astrology has mentioned a method where rectification can be done based on one event. There was recently a rectification challenge on this Forum using three events. I don't remember Unique's attempt or IF he participated, but I know that Matt was the closest to the correct answer, whatever the method. However, because Unique normally presents sound reasoning (to my eyes), I am forced to work through the math, which (though I was a math major in college!) I have been hoping to avoid. The claim was thrown on the table and, in the interest of at least LOOKING at anything that MIGHT be useful, I can't avoid it just because it's momentarily unpleasant.
There is so much more to say on this topic...and I look forward to reading everyone's take on this topic.
How many Methods do I need? After 20 years, it still seems like the answer must surely be "ONE MORE." The last two techniques that I have found useful and often PROFOUND are Topocentric Primary Directions and PSSR's. I always feel that I am "getting there", but that it is like the mathematical paradox, where I continually HALVE the distance to the "finish line" each time, but thusly never actually reach the finish line. As my wife would corroborate, I am definitely a "work in progress" and my Astrology is the same...
