Under astrology, there must be some sort of causal or mechanism link to the planets and our behavior, even if they don't determine the outcomes.
If the connection between the planets was not obtained by recognition of a mechanism or correlating results (there can only ever be one Janaury 10th 2001),
where did all of this astrological knowledge come from? (im sincerely asking

)
Hi
I think I get your distrinction.
It's kind of like you being very strong or being very beautiful.....
Any person can learn to be strong, they can press weights - take steriods etc... but the natrualyl born strong don't need to work at it.... Hence being said to be natrually strong is a resource you have.
Beauty is probably better (again a non bueatiful person can have cosmetic surgery etc).... The natrual beauty has it already.
Astrology basicaly is a snap shot of your resoruces... it doesn't cause strongess of beauty, just gives you a mechanisim for saying this child is likely to develop these resources.
I guess when it coems to how astrology works, there may be more around the causal factors, but that is really beyond exploration and proven. I've done some pre-epoch work before now, conception charts and they have an an interesting interplay with the native.
In a conception share the moon is where the ntal charts ascendant is, and vice versa (sorry this may get too technical).... so actually fact the moment of fertilisation is important and does relate to when the person is born.... this of course theory rather than verifable.
As for where did it come from... eons ago....
Wiki says 3rd millennium BC.... long while BC.... Originally it was star gazing perdominantly to predict farming outcome... the moon was largely instrumental. As civilisation took off, the astrological interpretation of other planets grew, it's been passed down generation via word of mouth.
The first book in the UK that I'm aware of was 1346 or there about - William Lilly's Christain astrology
Historically the celestial bodies that were used:
Sun
Moon
Merucy
Venus
Mars
Jupiter
Saturn
Were the only planets... It predicted the weather focast, good times to start wars, predicted famines etc etc.....
Each planet has a meaning, which is then helped or hindered by how it relates.
Mars = agression - you could have mars in a good sign to get things done (Mars used as energy), but if Saturn (inhibitor) is making a harsh aspect it it, Saturn will hinder Mars' expression... so instead of getting things done, the native will experience lots of blocks to get things done, which can be exhausting, or create agressive outcome, or a need to develop a lot of coping mechnaisims.
Hence each planet has interpretations. It's these interpretations that make Astrology (interpretation of planetary movement), different from astrology - mapping out the movement of the stars.
Hence it's real origin was probably global use as a weather monitor in the first place, natures natrual calender in seassonal countries, and direction setter to sailors and fishermen.
From early civilisation, it has been incororated into what is now knonw as science, it was part of astronomy, it si part of the hypocratic oath I beleive - sits in the terratory of not conducting surgery when the atrological conditions are bad (basically the native would bleed out).... Only relatively recently did the sciences split... and to be honest with you they are largely the same...
Take human behaviour:
* Psycology
* Behavioural ecconomics
* Ecconometircs
* Statistics
* Operations research
* Market Research
* Social Research
Are all different but they can all look at human behaviour and suggest ways to change it..... They are not in practice all that different they just add a different perspective. All of these disciplines are not perfect, humans are complex, their behaviours highly complex...
Does this help? Ask questions as much as you like, I might run dry of answers but I'll do my best to help. I do genuinely beleive you are interested - rather than screaming unproven and not contributing much to the discussion....
