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.
Perhaps the human fascination with fire stems from the totality of its sensory stimulation. The fire gives a flickering and glowing light, ever moving, ever changing. It crackles and hisses and fills the room with the smells of smoke and wood and perhaps even food. It penetrates us with its warmth. Every sense is stimulated and all of their associated modes of perception, such as memory and an awareness of time, are also brought into play, focused on the one experience of the fire. Together they create such an intense feeling of reality, of the "here and nowness" of the moment, that the fire becomes completely captivating.
No legislation could prevent the making of verbal pictures: God walks in the garden, He stretches out His arm, His voice shakes the cedars, His eyelids try the children of men. To forbid the making of pictures about God would be to forbid thinking about God at all, for man is so made that he has no way to think except in pictures. But continually, throughout the history of the Jewish-Christian Church, the voice of warning has been raised against the power of the picture-makers: “God is a spirit”, “without body, parts or passions”; He is pure being, “I AM THAT I AM”.
The fact is, that all language about everything is analogical; we think in a series of metaphors. We can explain nothing in terms of itself, but only in terms of other things.
