A Grand Scheme of Things?

Gebser's model, which has underlain the last several posts, is one way of looking at ourselves over the not-so-long span of our existence. We moderns tend to discard the past, especially the distant past, because we have been taught to believe that our eldest forebears were, well, more or less childlike and naive, not particularly bright (like we are today), and rather helpless in the face of the big, bad world into which they were thrown. This is, of course, a self-aggrandizing, egotistical, and arrogant belief. Maybe that's why we take to it and hold on to it so dearly. What I like most about Gebser's model is his insistence on (and documented support for) the fact that humans have always been intelligent (though there have always been geniuses and idiots among us) and whatever it is that we humans figured out is still of value to us today. In other words, we can learn from them, if we're only willing to take them seriously and take a serious look at all they did.

Gebser's ideas are also not new. He's not the first person to come up with the idea that change may be "built into the system", in a manner of speaking. He links his model to what he sees to be as evidence of changes in human mentation. Eons before he came up with this approach, however, the topic of cosmic change, let us say, a Grand Scheme of Things, was a highly developed science (using the word in its most fundamental sense: "a way of knowing"). Have you ever heard of the Precession of the Equinoxes? Most haven't, so let me explain it briefly, for it forms the basis of one of humankind's oldest models of change, one that might even qualify as that elusive Grand Scheme of Things.

Up front, a few basic facts and tidbits of knowledge that are necessary to understand the concept. The earth rotates on its axis, once every 24 hours (or one day). The earth revolves around the sun once every 365.25 days (or one year). The earth's axis is tilted at about 23 degrees; that is, it does sit perfectly vertically and the path of revolution around the sun is elliptical. When viewed from outside, the earth would appear to "wobble" and it is sometimes closer to the sun and sometimes actually vertical in relation to the suns's axis, and this is what causes the seasons, which are experienced most clearly in what are called the temperate climate zones. Now, this "wobble" isn't a shaky kind of wobble and if we could push a stick through the earth (like through an apple) from north to south and we observed the point of the stick from a great distance, we would see that it inscribes a circle. The fact worth noting is that it takes about 26,000 years to complete that circle.

The moon revolves around the earth, the earth around the sun, the sun around the center of the Milky Way (our galaxy) and so on. Everything out there in space is moving. We, of course, don't have the sensation that we're moving, so if we go out, say, every night at the same time and look up at the stars, we would notice that they don't always appear in the same place. They appear to be moving, albeit slowly, but moving nevertheless, but it takes a very long time to recognize that they are.

OK, so, if we went out at night on the first day of spring (March 21, the so-called vernal equinox) and looked due east, we would see a certain set of stars on the horizon. As it turns out, there are several sets of these stars, called constellations, which are familiar to us from astrology (hence the hapless pick-up line, "What's your star sign?" As most of you know, there are twelve of these signs, one for every month of the year, even though we count our months from 1 to 28, 30 or 31 days, and the astrological months always start around the 20th to the 22nd of each calendar month.

Well, you may be wondering where all of this is leading, but you'll have to come back next time for me to tell you.
