It’s quite useful to judge people by their appearance, through which characteristics can be easily found out. However, hair and the top on the head are featureless. For hair can be changeable and imitable. If we try to compare through these parts, which are rather common and misleading, then what will happen to the cognition?
These vertexes are reproduced from books, and belong to some people who have already been defined for their characteristics (maybe famous ones, or ordinary one). While the large format pictures only show their vertexes and hair, their features are omitted, even the hair are dissolved through CMYK color model after reproduction.
Then whose hair is this? Who is its holder? Clues are complicated and confusing if we stick to the previous custom of cognition. And this is not only a choice to “yes” or “no”.
So let’s return to hair. How do we understand it? Moreover, how human’s cognition has affected the objects themselves?
