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.
You’ve likely heard of Parkinson’s Law, which states that tasks expand to fill the amount of time allocated to them. But you might not have heard of the lesser-known Parkinson’s Law of Triviality, also coined by British naval historian and author Cyril Northcote Parkinson in the 1950s.
The Law of Triviality states that the amount of time spent discussing an issue in an organization is inversely correlated to its actual importance in the scheme of things. Major, complex issues get the least discussion while simple, minor ones get the most discussion.
In biology, when researchers want to observe animals in their natural habitat, it is paramount that they find a way to do so without disturbing those animals. Otherwise, the behavior they see is unlikely to be natural, because most animals (including humans) change their behavior when they are being observed.
