By the example of in language objectified smell cognition situation in the book are studied the specific characteristics of categorical division of reality. Using the method of modelling it is shown how the basic ontological categories are realized by a man (among them subject, object, perceptual action, space, time, tool, result). In the process of studying the mental representation of events in the German language is described the relation between the conceptual and linguistic levels. By the example of the verbalized smell cognition situation has been worked out the ideal model of event-concept: also are analyzed the preconditions, which influence the form of the proposition describing the situation of olfactory perception.
