Leonardo da Vinci
“Looking is giving a direction to one’s sight. A bird is an
an instrument………it opens its wings quickly and
sharply, bending in such a way that the wind…
raises it. And this I have observed in the flight
of a young falcon above the monastery at
Vaprio, on the morning of 14 April 1500.”
We tend to notice things which are directly relevant to our interest and ignore the rest. Blinkered by habit we glance rather than look at things. In effect, the eye sleeps until the mind wakes it with a question. What you see and what you notice are not the same thing. For example, you will, of course, have noticed the deliberate mistake in the preceding thought experiment and it’s not a spelling mistake.
As I wrote these words, I was reminded of an ancient Chinese story about a rainmaker who was hired to bring rain to a parched part of China. The rainmaker came in a covered cart, a small, wizened, old man who sniffed the air with obvious disgust as he got out of his cart, and asked to be left alone in a cottage outside the village; even his meals were to be left outside the door.
Nothing was heard from him for three days, then it not only rained, but there was also a big downfall of snow, unknown at that time of the year. Very much impressed, the villagers sought him out and asked him how he could make it rain, and even snow. The rainmaker replied, “I have not made the rain or the snow; I am not responsible for it.” The villagers insisted that they had been in the midst of a terrible drought until he came, and then after three days they even had quantities of snow.
“Oh, I can explain that. You see, the rain and snow were always here. But as soon as I got here, I saw that your minds had become lazy and that you could see but had forgotten how to look. So I remained here until once more you could see what was always right before your eyes.”
