That a certain power, derived from æthereal nature, pervades the whole earth, is clearly evident to all. Fire and air are altered by the motions of the æther, and these elements, in their turn, encompassing all inferior matter, vary it, as they themselves are varied, acting equally on earth and water, on plants and animals. The Sun, not only by the change of the seasons, brings to perfection the embryo of animals, the buds of plants and the springs of water, but also, by his daily movement, brings light, heat, moisture, dryness and cold. The Moon, being of all the heavenly bodies the nearest to earth, has also much influence, and things animate and inanimate sympathise and vary with her. By her changes rivers swell or are reduced, the tides of the sea are ruled by her risings and settings, and animals and plants are influenced as she waxes or wanes. The stars also produce in the ambient[1] many impressions, causing heats, winds and storms, to the influence of which earthly things are subjected. The force of the Sun, however, predominates, because it is more generally distributed; the others either co-operate with his power or diminish its effects. The Moon more frequently does this at her first and last quarter; the stars act also in the same way, but at longer intervals and more obscurely than the Moon. From this it follows that not only all bodies which may be already in existence are subjected to the motion of the stars, but also that the impregnation and growth of the seeds from which all bodies proceed are moulded by the quality in the ambient at the time of such impregnation and growth. When, therefore, a person has acquired a thorough knowledge of the stars (not of what they are composed, but of the _influences_ they possess), he will be able to predict the mental and physical qualities and the future events in the existence of any one whose actual moment of birth is accurately given to him. But the science of astrology demands great study, a good memory, constant attention to a multitude of different points and much power of deductive judgment; and those persons who undertake to cast horoscopes without possessing these qualities, must necessarily make frequent mistakes in their judgments, which, perhaps, accounts for much of the disbelief which exists as regards the power of astrology; but it is unfair to blame the science for inaccuracies which are only the result of the ignorance of its exponents. No one should attempt to pronounce judgments on the influence of the stars without having first given years of study to the subject; and even then, unless he should have been born under certain influences,[2] he will never become a proficient astrologer.
