Abstract
The author investigates the content of the notion of subject from the evolutionary-epistemological point of view. She claims that evolutionary epistemology does not clarify this problem by itself and argues that this state of affairs raises a number of problems such as absolutization of adaptationism, biologism in knowledge, lack of a clear demarcation between animal cognition and human cognitive activity. It is argued that a man is the only subject of cognition in evolutionary epistemology. Inasmuch as person constructs and enriches the environment he becomes a pressure factor by himself. This claim is argued to counter the thesis of adaptation. So adaptationist interpretation of the evolution of human cognitive activity is insufficient. The phenomenon of environmental change through the development of cognitive abilities by the person is represented in society, communication and culture. Cognition is determined by anticipating the result of purpose. In this connection, the constructive activity of the cognitive person confronted with the limitations of her own cognitive capabilities and environmental restricting factors. Thus, the evolution of man is considered as self-development, which is carried out through the creative overcoming external and internal constraints through the constructive activity of the agent of cognition.
