Realism Versus Antirealism

The conceptualization of the behavioral phenomena is one of the most controversy subjects from realism and antirealism perspective. The individuality of humans' perception and behavior would give the idealist antirealists, such as Berkeley, a golden chance to say that it is impossible to view it as mind-independent entity. However, as a realist, I argue that the behavior exists with or without our perception. To illustrate the independent existence of human behavior I am going to put forward their claims about the presence of color they sees that if we cant see then, there is nothing perceived as color. So, for the color to be identified it must be perceived by others. For human behavior; is the presence of the perception of the "other being" is necessary for the identification of the behavior? What about if a person is by himself and eating who else, other than himself, perceive and identify his behavior? If an antirealist would answer that "himself" identified him self's behavior then I would ask: What about the involuntary behaviors If the answer is yes for the conscious/voluntary behavior what about the unconscious/involuntary behaviors. What is the importance of our realization of can ident other is necessary for the identification of the behavior? For example the eating behavior, are we always aware/ conscious of this behavior? What about

ask: What do we mean by perception? Is it our observation (sight)? Or is it our hearing? By which one of the five senses we perceive human's behavior? We perceive the behavior either by one or a combination of senses "the necessity of the presence of the other to perceive the behavior?"
