I think we art the best because we are smart, talented, good at quittich, pretty, and alot more!
Similar to how the four elements depend on each other and are necessary to create and support life here on Earth, the balance between the four houses are essential for maintaining a decent education system for little wizards! :D
I believe Jo herself even drew parallels between those two subjects.
Gryffindor - fire
Slytherin - water
Hufflepuff - earth
Ravenclaw - air
In contrast to what I just said - Maybe this is why we're the best.
"In traditional cultures, air is often seen as a universal power or pure substance. Its fundamental importance to life can be seen in words such as aspire,inspire, perspire, and spirit, all derived from the Latin spirare ("to breathe")."
Lqtm, slippery. :D I don't know much about Greek philosophy, but I am a pretty Sirius astrology nerd. You know - stars n' stuff.
In the Zodiac, fire (Gryffindor) signs (Aries, Sagittarius, and Leo) are emotional, volatile types who are adventurous, powerful, and often inspirational. In one word, fire is action.
Earth (Hufflepuff) signs (Taurus, Virgo, and Capricorn) are in constant touch with the material world. Always practical, they are stimulated by the tangible, elegant, and luxurious. In one word, earth is sensation.
Air (Ravenclaw) signs (Aquarius, Gemini, and Libra) are mental creatures desirous of contact, communication, and relationship. They are the original thinkers, and the "bearers of human news." In one word, air is thought.
Water (Slytherin) signs (Pisces, Scorpio, and Cancer) are silent and mysterious types who perceive what others cannot. These people "have the potential for the depths of darkness or the heights of mysticism and art." In one word, water is emotion.
Here's another link. It's basically comparing the houses and the elements. Which is good, because I had trouble grasping the whole Water/Slytherin and Earth/Hufflepuff connections. http://www.lelandra.com/tarotbook/harrypotterelements.htm
Wow! THat's cool!!!
