Subject is one of the two Boulgakoff s key notions. The second one is predicate. Predication is a universal process. As the language connects two sides of reality ideal and empirical, every utterance is the product of the process of predication, the self-revelation of the subject, its realization hic et nunc. Verbs with their tense system introduce the temporal factor, case and numeric systems introduce the space factor.
Subject is no more free of the material world.
There are no pure words , logos , in real languages as there are no holy people in this world. Words have their roots in ideas, but in their phenomenal, historical existence they are marked with the human subjectivity and psychology. That is why every utterance even if it is a set-phrase or a quotation is a unique speech act, not simply a reproduction of what has already existed. Here we come to the dialogical treatment of language and discourse. Since logos transformed into this or that individual s word, became perspectivised, the question of how communication is possible arises.
