1. Life is short, Art
long, Experience not easily obtained, Judgment difficult, and therefore it is
necessary, that a Student not only exercise himself in considering several
Figures, but also that he diligently read the writings of others who have
treated rationally of this Science, and make it his business to find out the
true natural causes of things by experiments, to know the certain places and
processions of the Planets and Fixed Stars, Constellations, etc., but above all
to be a passionate lover of truth.
2. The Principles of Art are three:
Reason, Sense, and Experience, but the Principles of Operations four, viz.: The
Planets, The Parts of Heaven, The Fixed Stars, and the Site or Position of all
those in respect of one another.
3. There are some things perfectly
known, as the Circle of Ascension; some in a competent measure, as the
Revolution of the Sun; some may be known although they yet are not, as the
Revolution of the Superiors; some things fall under knowledge, yet cannot be
exactly known, as the precise Ingress of the Sun into the Equinoctial point;
some are neither known, nor can be known, as the complete commixtures and
distinct virtues of the Stars.
4. It is much worse for an Artist to
conceive he knows those things which he is ignorant of, than to be ignorant of
those thing which he ought to know.
5. Mean learning with an excellent
judgement, avails more than a mean judgement with the greatest learning, yet is
judgement with the greatest learning, yet is judgement very much assisted and
perfected by learning; but everything prospers better, and is far more easily
perfected that has nature for its guide and favourable stars, than that which is
attempted by human industry though never so diligent.
6. He that has too
great a conceit of himself will be apt to fall into many errors in his
judgement; yet on the other side, he that is too diffident, is not fit for this
Science.
7. He that would truly promote Art must insist as much on the
confutation of false opinions delivered by others, as in the declaration or
truth.
8. An Astrologer is so far only true and honest, as he depends in
his conjectures on principles of natural philosophy, and since those Arts which
are inherent in their proper subjects, cannot promise any certainty concerning
matters to come, the Astrologer ought never to pronounce anything absolutely or
peremptorily of future contingencies.
9. Truths of themselves are to be
desired, for Science itself is a certain good, now the expectation of future
good very much delight us, and on the contrary, when future evils are foreseen,
we may either avoid them, mitigate them, or at least bear them more
contentedly.
10. Heaven is the instrument of the most High God, whereby
he acts upon, and governs inferior things.
11. He that asserts things
that can never be proved by experience is deceived and ambitious, but thus it
always happens, those that are most ignorant of Art delights to boast of doing
things different or wonderful.
12. It is all one as to promoting of Art,
etc., and the knowledge thereof, either from nativities known, to predict what
shall happen, or after accidents have happened, to discover the Nativities
before unknown which are thereby rectified, but as to vulgar opinion, the first
way far exceeds the last.
13. He that goes about to destroy Art, is far
worse than he that is unskilled in it, for his mind is full of malice and
idleness as well as ignorance.
14. Men may be said almost to be
compelled by the Stars, even in voluntary actions, by means of their corrupt
affections and ignorance.
15. Always deliver judgements from the Stars
in general terms, or if thou dost otherwise let it be when thou hast very
evident testimonies and in great and weighty matters.
16. We ought not
to use arguments or tedious discourses in giving judgement, much less
flatteries, but only to pronounce what is known by experience and firm
reason.
17. A main reason why events are so rarely foretold by
Astrologers, is because the Art is yet but imperfectly discovered, for hitherto
those that have been most excellent in it, being commonly old persons, have
despaired to live to see the fortunes of children newly-born, and the Nativities
of persons grown up, being uncertain, they scarce thought them worth so much
labour.
18. When true genitures exactly taken in accidents prove false
or absurd, and not agreeable to the things signifies, they are to be accounted
monstrous, and are to be avoided as anatomists do monstrous bodies in their
dissections; for they overthrow Art.
19. Generals are to be gathered
from Singulars, and Singulars from Generals, and an Artist ought always to learn
to distinguish between that which is by itself, and that which is only by
accident.
20. The strength and efficacy of Fixed Stars is to be
considered from their magnitude, their splendours, their natures or properties,
their nearness to the Ecliptic, their place in the World, their multitude, their
first oriental appearance, the purity of their place, the similitude or
agreement of the body or rays of a Planet with them and their circle of
position.
21. The Light of the Time is the Sun in the day, and morning
twilight; and the Moon in the night when she is above the Earth, and in her
morning rising; so that sometimes their may be two Lights of Time, sometimes it
so happens that there is none.
22. When a Planet is within five degrees
of the cusp of any house, it shall be accounted to have virtue in that house
though actually posited behind the cusp in another house.
23. Not only
Trines and Sextiles may be counted friendly aspects, but even Squares and
Oppositions too, if there happen a Reception.
