The concept of beauty, according to philosophy, has evolved in various ways. Plato considered beauty fundamentally as an ideal. In this sense, there is only one true beauty: the prototypical, the exemplary, the one that belongs to the world of the ideal and that serves as a model for the artist for his creations. According to this, true beauty, then, only takes place in the soul, and the only way to access it is through philosophy.
Kant, for his part, distinguished two types of beauty: free, which appeared naturally and without arrangements, and adherent beauty, which is subject to the rational judgment that hopes to find in it a series of attributes according to which the object is considered as beautiful.
Currently, the branch of philosophy that deals with beauty is aesthetics. As such, Aesthetics is in charge of studying the perception of beauty and the principles that govern it. It is applied in the study of Art Theory.
