There are various means of foreknowledge, but all cannot be called scientific, although they may be the subject of scientific scrutiny. Inspiration or revelation escape our apprehension. What we know as the gift of the Spirit does not lend itself to scientific empiricism. Direct perception, as in clairvoyance or seership, is allied to certain temperamental peculiarities which can be noted but barely accounted for. Mediumism and obsession may sometimes be the source of foreknowledge of events, and these are the legitimate subjects of study by psychologists. To these we may add the various forms of Automatism when applied to divination, and Numerology or Kabalism. The latter, while depending on an universal symbolism and the geometrical relations of thought, is somewhat distinct in that it lends itself to empirical test. Indeed, it may be said that all the foregoing methods of foreknowledge, except direct revelation, may be rendered scientific. That they are not yet so is due to our defect of knowledge concerning the nature and constitution of man. In effect we make final reference to Astrology as the only means of scientific foreknowledge known to man, and in this we must include the physical phenomena which have direct relation to astronomical facts as well as anything we may argue concerning the action of the planets upon the minds of men and the disposition of human affairs. Astrology lends itself readily to experimental test. It does not necessarily assume a causative relationship between man and the various bodies of the solar system, but it is open to show that there is an actual relationship between the state of the heavens at the moment of a person’s birth into the world and the character and experience of that person through life. There is no need in this place to elaborate the argument. The facts are sufficiently well attested in the experience of all who have taken the trouble to apply the ordinary tests. As to character, Ptolemy affirms that Mercury is the indicator of the rational powers, the Moon of the natural powers. By the rational he means those that are peculiar to man, by the natural, those that are common to man and the lower animals. The distribution of the faculties and powers are thus symbolically located— [Illustration: Figure 5.]
