<b>That last part reminds us that Religion and Philosophy both fall into the category of the 9th House in Astrology.</b></p>

People (and particularly Sagittarius, the 9th zodiac sign) can at times become quite dogmatic and rigid about their ideas the same way they can become dogmatic and rigid about their religion.</p>

I met a guy who had a Ph. D in Philosophy but who did not know what the Trivium Method was... his response to me saying Philosophy falls in the cateogry of the 9th house was "show me a single academic philosopher who takes astrology seriously".</p>
