What a beautiful one! It’s fair to say that what I, a human, observe as beauty is not necessarily aesthetic, yet is attractive, in the sense that it completes patterns and completes me as an observer. The ways in which it does so, through colour, shape, form or just presence, are gifted by Western culture to art. Don’t be fooled by that. Art and science are not distinct pursuits.
The human body is a measuring device. What does it measure? Why, that other thing that has been excluded from science: spirit. There is no way to define spirit. That’s kind of the point. Nonetheless, it can be measured, through artfulness and the aesthetic sense of humans, birds, insects, fish and much more.
