Now, having given the philosophy by which the good and the bad operates, and as elucidated by the birth numbers on the wonder wheel, it only remains to explain how these different generations are alike made better or worse.
I have noted generations, or generations inside of generations, or wheels inside of wheels, from Neptune, 14 years, to the earth revolving 20 degrees in 2 hours; like cycles and epicycles from highest to lowest. The higher generations are modified by as many lower generations, as the time of the lower may be multiplied into the higher. This orderly system of multiplication or division, according to which way you figure, is the mathematical or scientific part of astronomy, and a like orderly system of judging the effects of these modifications is the scientific part of astrology.
People born in the same generation get, generally, the good or the bad that belongs to the generations in which they were born, but, more nearly alike in some one or more of these generations, the nearer they are to the same day and hour. From the Neptune generation, if born between seven and fourteen years apart, they might get only a little general sameness in their Neptune qualities, while the Uranian, Saturn, Jupiter and Mars qualities would be different, and the others might or might not be the same. We are stating this only on a general principle, and not to exactness, merely to show the philosophy of differentiation. As a matter of fact, of course, we know that no two persons, nor two blades of grass are precisely alike, even though they be twins.
In this order of generations, or planetary influences kindly note this fact: - Leaving out Neptune, the sun stands in the centre of them in length of generation, but, do not forget that the sun does not make the movement, of 30 days. It is the earth that moves. So let us take sun out of the order, for the purpose of elucidating a much misunderstood matter concerning ancient claims, and put earth in the sun's place and we would then have earth in the centre of this array of influences. As follows: - Uranus 7 years, Saturn 2 1-2 years, Jupiter 1 year, Mars 2 months, earth 30 days, Venus 19 days, Mercury 7 days, moon 2 1-2 days, and the Mundane influence (or mid-heaven) 2 hours. Was not this what the anclents meant by the earth being in the centre. In matters of calculation it does stand in the centre of yearly considerations and daily considerations, and might not Galileo and the priests have contended over Astrology matters which they did not clearly understand. Surely the builders of the Pyramids and the Sphinx, did not believe the sun revolved about the earth; nor did Isaiah believe the earth was flat when speaking of "sitting on the girdle of the earth."We speak of this matter here because, in consideration of the order of generations (or planetary influences) it seems as if this may show the ancient meaning when sneaking of the earth in the centre, and in so speaking the sun was not considered In the question at all.
From the sun outward towards Neptune, all astronomical books today show earth in the centre of the bodies revolving about the sun, when including moon, and the axis of the earth,
