We propose a model which argues that aesthetics is based on biosemiotic processes and introduces the non-anthropomorphic aesthetics. In parallel with habit-taking, which is responsible for generating semiotic regularities, there is another process, the semiotic fitting, which is responsible for generating aesthetic relations. Habit by itself is not good or bad, it is good or bad because of semiotic fitting. Defining the beautiful as the perfect semiotic fitting corresponds to the common conceptualisation of the aesthetic as well as extends it (...) over all umwelten. Perfection is not omnipotence, it only means the omnirelational semiotic fitting in the umwelt, or harmony with context. The process that presents something to be perceived as beautiful is of the same kind as the semiotic process that builds something to become beautiful. The argument is based on the observation that learning has a tendency towards perfection, until it is grounded. Semiosis is usually biased towards semiotic fitting, which stepwise leads towards perfection, and thus towards beauty. Such a general semiotic model implies that beauty is species-specific; that it is not limited to the sphere of emotions; that the reduction of the evolution of aesthetic features to sexual selection is false; and that humans should learn the aesthetics of other beings in order to avoid destroying valuable biocoenoses.
