He then proceeds to show what this just astrology should comprehend—as, 1, the doctrine of the commixture of rays; 2, the effect of nearest approaches and farthest removes of planets to and from the point overhead (the planets, like the sun, having their summer and winter); 3, the effects of distance, 'with a proper enquiry into what the vigour of the planets may perform of itself, and what through their nearness to us; for,' he adds, but unfortunately without assigning any reason for the statement, 'a planet is more brisk when most remote, but more communicative when nearest;' 4, the other accidents of the planet's motions as they pursue
Their wand'ring course, now high, now low, then hid,
Progressive, retrograde, or standing still;
5, all that can be discovered of the general nature of the planets and fixed stars, considered in their own essence and activity; 6, lastly, let this just astrology, he says, 'contain, from tradition, the particular natures and alterations of the planets and fixed stars; for' (here is a reason indeed) 'as these are delivered with general consent, they are not lightly to be rejected, unless they directly contradict physical considerations. Of such observations let a just astrology be formed; and according to these alone should schemes of the heavens be made and interpreted.'
The astrology thus regarded by Bacon as sane and just did not differ, as to its primary object, from the false systems which now seem to us so absurd. 'Let this astrology be used with greater confidence in prediction,' says Bacon, 'but more cautiously in election, and in both cases with due moderation. Thus predictions may be made of comets, and all kinds of meteors, inundations, droughts, heats, frosts, earthquakes, fiery eruptions, winds, great rains, the seasons of the year, plagues, epidemic diseases, plenty, famine, wars, seditions, sects, transmigrations of people, and all commotions, or great innovations of things, natural and civil. Predictions may possibly be made more particular, though with less certainty, if, when the general tendencies of the times are found, a good philosophical or political judgment applies them to such things as are most liable to accidents of this kind. For example, from a foreknowledge of the seasons of any year, they might be apprehended more destructive to olives than grapes, more hurtful in distempers of the lungs than the liver, more pernicious to the inhabitants of hills than valleys, and, for want of provisions, to monks than courtiers, etc. Or if any one, from a knowledge of the influence which the celestial bodies have upon the spirits of mankind, should find it would affect the people more than their rulers, learned and inquisitive men more than the military, etc. For there are innumerable things of this kind that require not only a general knowledge gained from the stars which are the agents, but also a particular one of the passive subjects. Nor are elections to be wholly rejected, though not so much to be trusted as predictions; for we find in planting, sowing, and grafting, observations of the moon are not absolutely trifling, and there are many particulars of this kind. But elections are more to be curbed by our rules than predictions; and this must always be remembered, that election only holds in such cases where the virtue of the heavenly bodies, and the action of the inferior bodies also, is not transient, as in the examples just mentioned; for the increases of the moon and planets are not sudden things. But punctuality of time should here be absolutely rejected. And perhaps there are more of these instances to be found in civil matters than some would imagine.'
The method of inquiry suggested by Bacon as proper for determining the just rules of the astrology he advocated, was, as might be expected, chiefly inductive. There are, said he, 'but four ways of arriving at this science, viz.—1, by future experiments; 2, past experiments; 3, traditions; 4, physical reasons.' But he was not very hopeful as to the progress of the suggested researches. It is vain, he said, to think at present of future experiments, because many ages are required to procure a competent stock of them. As for the past, it is true that past experiments are within our reach, 'but it is a work of labour and much time to procure them. Thus astrologers may, if they please, draw from real history all greater accidents, as inundations, plagues, wars, seditions, deaths of kings, etc., as also the positions of the celestial bodies, not according to fictitious horoscopes, but the above-mentioned rules of their revolutions, or such as they really were at the time, and, when the event conspires, erect a probable rule of prediction.' Traditions would require to be carefully sifted, and those thrown out which manifestly clashed with physical considerations, leaving those in full force which complied with such considerations. Lastly, the physical reasons worthiest of being enquired into are those, said Bacon, 'which search into the universal appetites and passions of matter, and the simple genuine motions of the heavenly bodies.'
It is evident there was much which, in our time at least, would be regarded as wild and fanciful in the 'sound and just astrology' advocated by Bacon. Yet, in passing, it may be noticed that even in our own time we have seen similar ideas promulgated, not by common astrologers and fortune-tellers (who, indeed, know nothing about such matters), but by persons supposed to be well-informed in matters scientific. In a roundabout way, a new astrology has been suggested, which is not at all unlike Bacon's 'astrologia sana,' though not based, as he proposed that astrology should be, on experiment, or tradition, or physical reasons. It has been suggested, first, that the seasons of our earth are affected by the condition of the sun in the matter of spots, and very striking evidence has been collected to show that this must be the case. For instance, it has been found that years when the sun has been free from spots have been warmer than the average; and it has also been found that such years have been cooler than the average: a double-shotted argument wholly irresistible, especially when it is also found that when the sun has many spots the weather has sometimes been exceptionally warm and sometimes exceptionally cold. If this be not considered sufficient, then note that in one country or continent or hemisphere the weather, when the sun is most spotted (or least, as the case may be), may be singularly hot, while in another country, continent, or hemisphere, the weather may be as singularly cold. So with wind and calm, rain and drought, and so forth. Always, whether the sun is very much spotted or quite free from spots, something unusual in the way of weather must be going on somewhere, demonstrating in the most significant way the influence of sun-spots or the want of sun-spots on the weather. It is true that captious minds might say that this method of reasoning proved too much in many ways, as, for example, thus—always, whether the sun is very much spotted or quite free from spots, some remarkable event, as a battle, massacre, domestic tragedy on a large scale, or the like, may be going on, demonstrating in the most significant way the influence of sun-spots or the want of sun-spots on the passions of men—which sounds absurd. But the answer is twofold. First, such reasoning is captious, and secondly, it is not certain that sun-spots, or the want of them, may not influence human passions; it may be worth while to enquire into this possible solar influence as well as the other, which can be done by crossing the hands of the new fortune-tellers with a sufficient amount of that precious metal which astrologers have in all ages dedicated to the sun.
That the new system of divination is not solely solar, but partly planetary also, is seen when we remember that the sun-spots wax and wane in periods of time which are manifestly referable to the planetary motions. Thus, the great solar spot-period lasts about eleven years, the successive spotless epochs being separated on the average by about that time; and so nearly does this period agree with the period of the planet Jupiter's revolution around the sun, that during eight consecutive spot-periods the spots were most numerous when Jupiter was farthest from the sun, and it is only by going back to the periods preceding these eight that we find a time when the reverse happened, the spots being most
