As I have repeatedly written in this space, I used to collect and study butterflies quite seriously when I was a kid. It meant that I had to wait for the emergence of these rare species that I was after in the forest and the fields, often for hours, sometimes even for days.
There was a special quality in the time spent waiting for the butterflies. Butterflies could pop into view from any directions in the space around you. Once an interesting butterfly has appeared, you had to react very quickly, as otherwise the species might disappear. The combination of a long wait and a quick response characterized my butterfly time.
The human brain, once it learned something from a particular experience, can apply the resulting circuit to many other things. Today, after having ceased the active chasing of butterflies, I sometimes feel that I am still waiting for rare species. The butterflies have turned into concepts, new ideas, interesting people, beautiful cultural artifacts. The butterfly time in my childhood has fine-tuned my sensitivities for the abruptly emerging things, preparing my body and mind for a quick reaction.
