When a person has his natal Mercury in Sagittarius, it is considered in detriment and thus in its lowest potency. Sagittarius is located directly opposite of the sign of Gemini, where Mercury is at domicile. The other sign where the planet is also in detriment is Pisces, where Mercury has its point of fall too. Mercury in Sagittarius is a rather impractical placement to have in a natal chart, as the expansive traits of Sagittarius are not helping the planet focus and instead make its energies scattered. On the other hand, Mercury placed here can be rather fun for the native, who will even consciously prefer not to be serious in his ways of thought.
Mercury in Sagittarius indicates a mind concerned with coding the mind at the largest level, whether in the form of higher spirituality, religion, philosophy, or other higher aspects of being human. In Sagittarius, Mercury is in the sign of his exile and is more concerned with attitudes than facts.
The result of this is often constructive, providing a clearer understanding of people’s social motivations and their actions. However, the natives may not realize the truth if they do not pay enough attention to detailed information, the basis of all logical thinking. We must remember that Sagittarius is in opposition to Gemini and square to Virgo , the signs ruled by Mercury .
It’s not that it’s an illogical position to be distant from home, it’s just that he doesn’t like to worry about very trivial things, with the banalities that most people with different positions focus on in their daily lives. It is a very good position of Mercury that makes the natives see the whole picture of things, as well as making them communicate with more sincerity and good humor.
People with this position can have almost prophetic ideas. This is because their concern with attitudes allows them to understand information that will be important to everyone. In this way, they can almost predict a “collective destiny.”
With this position of Mercury, the speech is direct. They usually say exactly what they think about something. They demand intellectual freedom, but their ideas rarely differ from traditional concepts or current social morality. Therefore, they are generally respected people in the community.
But, if social conformism goes too far, it can lead to hypocrisy, since your moral standards may not be better than other socially acceptable norms. At some point, they realize that an attitude is not necessarily correct simply because it is popular or dominant. At that point, any conformism you may have may end and a deeper consciousness may gain notice.
People in this position often want to join institutions of higher learning or social control. It is not uncommon to see them in universities, churches, philosophical doctrines, and government agencies. Their goal is to gain intellectual authority.
They like to consider themselves examples of conscience and truth. However, whether they are or not depends on the aspects formed with Mercury and his life experience. They tend to preach sermons and give extensive opinions on things that seem obvious to them, but may not be so clear to others. As a result, they risk becoming pretentious in the eyes of other people.
Sometimes there is a preoccupation with distant goals and higher ideals, which can lead the natives to not realize what is under their noses. As understanding tolerance is characteristic of the Sagittarius sign, people with this position in their chart must learn that they are not always in possession of the truth and that it is necessary to at least listen to people more or teach in a more pleasant or effective way.
