"it is not a science."
How can something that is actually based on science, that encapsulates all the 'sciences', eg. astrophysics, geophysics etc, not be a science? This is suggestive that only the surface interpretive dimension of astrology is being considered.
From NM Swerdlow, Professor in Department of Astronomy and Astrophysics at the University of Chicago in "Babylonian Theory of the Planets":
".. the systematic collection of celestial and meteorological omens as carried out in Mesopotamia required a systematic study of celestial & meteorological phenomena ... the collection and the interpretation of omens must be regarded as a science, in fact, as the first and most important science of antiquity...
" ... the Diaries as a whole are among the most extraordinary achievements in the entire history of science ...originally extending from the 8th-7th centuries [BC] to the 1st century [AD], (they) are by far the longest continuous scientific research, or should we say, a record of the longest continous scientific research of any kind in all of history, for modern science itself has existed for only half as long.
" ... nothing more clearly shows the scientific spirit of the Scribes, their principal science being the interpretation of omens, than this systematic collection of information, understood to be vital to the welfare of the kingdom, on a scale not seen again until the statistical and economic surveys of modern states in the 18th and 19th centuries.."
From Francesca Rochberg, "The Heavenly Writing - Divination, Horoscopy and Astronomy in Mesoptamian Culture":
"One cannot find in Mesopotamian society a comparable institutional separation between the two enterprises of "science" and "religion". Mesopotamian scribal scholarship supported a wide diversity of textual forms and content, including divination of all kinds (celestial being only one), mathematics, observation and predictive or theoretical astronomy.
"To imagine that celestial omen literature provided some sort of ground out of which prediction of phenomena came to be a new and scientific goal and a new kind of thinking merely recasts an outmoded historiography.
"Until the relatively recent turn away from the pervasive influence of the logical positivists on historians of science, when the model of western science provided the standard against which all other sciences would be judged, the ancient Greeks were assumed to be the inventors of science.
"In the history of astronomy, the recovery of the civilizations of the ancient Near East eventually necessitated the updating of the view of Greek astronomical science by an acknowledgement of the Greek debt to their near Eastern predecessors. Specifically, Greek astronomy came to be seen to depend in significant ways on technical details borrowed from the Babylonian tradition.
Personally, I don't see "skepticism" as being particularly useful or constructive, skepticism usually being a negative mindset that undermines, an attitude of systematic doubt that seeks to assert some level of control over efforts to understand that which is yet to be fully understood and appreciated.
Learning by rote & repetition is one way of learning and corroborating, however it usually fails to address the 'why' ... nor do I see skepticism as being in the true spirit of science or astrology.
Granted, skepticism may be a transitory phase in the sciences as Jupiter transits constellation Scorpio making itself known through the western tropical sign of Sagittarius.
This in itself presenting an opportunity to dig deeper ... and as an aside, it's probably worth keeping an eye on Mars as it challenges Saturn and transits Algol with this Full Moon, then opposes Jupiter conjoining Antares (forces accumulating in SE opposing NW) leading into Lunar Eclipse on 28th August, followed by the partial solar eclipse on Sept. 11.
Guess I should probably also mention I consider skepticism as being different to discernment. As a negative, turned on itself, skepticism would question that skepticism is a valid perspective at all.
However, I also tend to view the combination of "free will" to be something of an oxymoron. Once "free" is attached to something ... such as a legacy (will) or a desire propelling forward momentum ... "free" ceases ... until perhaps that time able to transcend one's own genetic etc legacy. Every choice made is a determination in the constantly shifting sands of time. Choice being a correlation that also has causes and effects.
Knowing may be subjective, but it also involves education ... and these days education is far more widely available than it once was via innovations such as the internet. Also involves discernment.
I think faith is fine unless its blind, can keep people on track until deeper understandings blossom in whatever area of practice - it's not exclusive to astrology. There's an element of "faith" at play in all the "sciences", from medicine to astrology and astrophysics etc.
