Western philosophy comes from Greece. Thales was born in the 1920s BC and died in the 40s. He is regarded as one of the seven sages of Greece. He believes that water is the mother of all things. Anrak Simini was a thinker who lived in the middle of the 5th century BC. He believed that everything was made up of wind. Heraclitus, one of the founders of dialectics who was born in 1930s BC and died in 1970s, believed that everything was caused by fire. In the 4th century BC, Ampedocles, a doctor and philosopher, integrated the opinions of his former philosophers, adding earth to their water, wind and fire, which became the four elements of all matter.

Gryffindor stands for fire, Ravenclaw stands for wind, Hufflepuff stands for earth and Slytherin stands for water. When the four elements coexist, a complete system is formed. But as we all know, they are also independent.

Gryffindor's dormitory is in the tower, which is related to the earth and the sky. Gryffindor's name comes from French Gryffindor, which means golden Griffin. Gryffindor is a creature of half lion and half eagle in Greek mythology. Later, Christianity often used it as a symbol of Jesus, because it represented the control of the earth (lion) and the sky (eagle).

Ravenclaw's dormitory is in the astronomical tower, which symbolizes the relationship between Ravenclaw and the sky, and the eagle is also a symbol of the sky.

Slytherin's dormitory is at the bottom of the lake, and the basilisk's secret room passage is under the girls' bathroom, which accords with the hint of water.
