The planets have exerted a tremendous influence on man. Some have made a life study of these motions and sometimes these observations were recorded. They drew conclusions as to the effects on people.
These findings were handed down to their pupils, their off string. These observations were expanded and new theories brought forward. The ancients named the stars and the planets after gods and ascribed particular traits to each one of them.
Their ignorance stems mainly from the fact that they have not studied the subject very well. They haven’t even taken the trouble of checking out a few things or reading some authoritative paper on the subject. Or maybe they just think that if one denies these influences, one is considered enlightened and not a pagan or so called “gullible fool”. Well each to their own!

Of course astrology is not without its sort comings. The astrologer can not foretell everything. Thank goodness for that!
