A hierarchical system of sense

During the Renaissance, the five senses were understood to form a hierarchical system from the highest sense of vision down to touch. Vision was correlated to fire and light, hearing to air, smell to vapour, taste to water, and touch to earth.

  1. ​Avatar: The Last Airbender​
  2. ​Prometheus​
  3. ​Blessed by the four elements​

Knowledge has become analogous with clear vision and light is regarded as the metaphor for truth.

Vision was correlated to fire and light.

Consider Prometheus. Fire is light is seeing is knowledge.

But fire is also heat.
