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.
A lot of people think dreams and drugs involve some magical inspiration. I think otherwise.
I rarely get inspired by dreams or drugs, but I have my own secret source of inspiration: mishearing other people. Somebody says something, I misinterpret it, and the misinterpretation is quite interesting – more interesting than anything I would have come up with on my own if asked to generate an interesting idea. Maybe it’s a clever joke or turn of phrase. Maybe it’s a neat idea. Sometimes I misunderstand people’s entire positions, and end up with positions much more interesting than the ones they were trying to push.
