A trait that is shared between Sagittarius and Gemini as sister signs is being simultaneously open and skeptical. Where the openness and skepticism comes from for the two signs are different.
With Gemini, it is an air sign that naturally rules over the 3rd House. The 3rd House shows objective thinking and primary education. Your neighborhood, a small, confined “world” is also shown in the 3rd House. Gemini itself represents youthfulness and the exciting exchange of communication that sparks learning due to being exposed to new concepts and ideas. Gemini, as a logical air sign, will ask, “Where are the facts? How do these facts logically tie altogether?” They will put their preconceptions and the new concept side by side. Their preconceptions often comes from what they’ve formulated themselves in their mind, what they’ve heard from others, and what they’ve learned in school – all of these spaces are limited spaces. From a confined, limited space, Gemini can learn to expand their mind. As an air sign, Gemini is able to channel their skepticism in a rational way, for their way of thinking is often logical and objective.
With Sagittarius, it is a fire sign that naturally rules over the 9th House. The 9th House shows subjective thinking and secondary education. The world itself is also shown in the 9th House. Sagittarius itself represents wisdom and the exciting thrill of exploration that sparks learning due to seeing the grandeur of all concepts and ideas on a grand scale. Sagittarius, as a passionate fire sign, will ask, “I’ve already seen so many things in the world, why should I believe in this?” They, like Gemini, will also put their preconceptions and the new concept side by side. Their preconceptions often comes from what they’ve found to believe in due to a lot of exposure and various life experiences – all of these origins are from open spaces. From a wide, grand space, Sagittarius can learn to mentally take root. As a fire sign, Sagittarius is able to channel their skepticism in a passionate way, for their way of thinking is often energetic and subjective.
