Foundation of perception and evaluation in aesthetic property of nature in quality expressive
The paper presents a grounding and the experience of application of a new approach to the characterization of aesthetic properties of nature as objective ones subjectively refracted in human perceptions and actions. A multidisciplinary view allows to characterize the natural-aesthetic in terms of the expressive, that is, the essential, avoiding superficial definitions of aesthetic qualities in terms of beautiful vs. ugly. An experiment with Russian schoolchildren and students, ongoing for years, shows positive effects.
