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.
I now use Are.na as a Memory Palace, separating my channels into rooms. For example, I have a channel that I call the Computation Room. It’s pretty generic and includes any type of block that relates to computation.
If I notice a pattern in the computation room I create a more specific channel in that room. I think of that more specific topic as an object within the room.
Then there are the adjacent topics that I often find even more exciting to focus on. For those, I choose a name that corresponds with the nature of a room and also its size. For example I have a channel called the Visual Computing Observatory. In my head I am imagining an actual observatory where I am looking and observing and studying a given topic.
