"Subject" as a result of perception and functional quality system
The author analyses the notion “subject” as the basis for the categories of objectness and substantiality which, in their turn, are connected with defining noun as a part of speech. The category “subject” is considered in broad philosophical and psychological aspects as a result of the process of perception and as a functional quality system. The author looks at the stages in forming the notion “subject” paying special attention to the functional relations between its qualities.
