Beauty is one word that describes beauty in the natural world. A natural object is one that is wholly without defect or injury, in its whole entirety, as perceived by the senses. Beauty is also commonly defined as the beauty of objects which makes those objects pleasurable to see. These objects can be nature itself or the human beings that are beholden to it. Beauty, along with beauty and art, is the most important subject matter of aesthetician philosophy, among the major branches of applied philosophy.
The study of aesthetic science seeks to reveal the relationships between the aesthetic values and the natural selections that appear in nature. It also seeks to reveal the connections between the psychological and the biological components of beauty. In this modern period, the concepts of beauty have undergone considerable change. Beauty, for example, was not only defined according to the visual sensibility of a person but it has also been determined according to the cultural norms of a society. Thus, the concepts of beauty are no longer the mere aspects of human mind but are formed according to social interaction and cultural patterns and values.
It is through the study of the relationship between the aesthetic principles and the brain that an explanation can be offered as to why some people are attracted to certain objects while others are repelled. For instance, the human brain has a specific preference for certain objects which appear to be of a higher value, such as faces, human beings and other animals. This is because the face of an animal, with its various parts and features, provides the animal with many possible advantages and which, at the same time, represents the primary basic need of human beings. Beauty then, appears to be a complex phenomenon rooted in the brain, through which the mind of a person directs its attention in order to find the most attractive features in any object.
