Air

In magical tradition, Air is the realm of the mind, the brain, the intellect and logical linear thought. The Airy side of us is the part that wants to learn, which is curious and tries to understand the true nature of things. It is youthful, light and energetic. Air can be quickness of thought, lightness of being, humor, the joy of life. The tarot card of the Fool springs to mind. This is ruled by Air and represents a stepping out into the unknown with joy; although this can be dangerous.
There is and excitement in Air. It values the new and untried. Air always wants to learn new things whatever the price. Air signs are good at starting anew, and at throwing old things away. Much more than Earth and water, though perhaps Fire rivals Air here. Air divides things into categories. It separates one thing from another. It gets to the point and is not �Wooly-Minded�. Computers, library classification systems, indeed all systems, are Air-related. Objectivity is something which can be developed by working with Air element.
Air is impersonal and detached; for emotion can distort our thinking processes. Air adheres to the letter of the law. Islamic Sharia law is a totally logical system. There is a list of crimes and a fixed set of penalties. Everyone knows exactly where they stand and, theoretically, the same treatment is meted out to all. This may be logical but it does not take account of another aspect of reality- individual circumstances. It is hard- nosed rather than soft in its approach.
The zodiac signs ruled by Air are
Aquarius the Water Bearer, symbol of the New Age
Libra the Scales,
Gemini the Twins
