Since ancient times the notion of beauty has been bothering not only scientists and philosophers, but also ordinary people who cannot understand why they are attracted to certain people and objects. As a result, a lot of beauty theories appeared. For instance, according to Pythagoras the most attractive were only those facial features which seemed to be very close to golden ratio, i.e. very symmetrical and mathematically proportional. Later on, the theory of averageness was suggested by Francis Galton which presupposed that mixing up facial features of many people in one face looks much more attractive that any individual in the world. I personally define ‘beauty’ as an abstract concept that is represented by a complex of specific traits and features of a concrete object that brings aesthetical pleasure to its observer.
