A theory of the city must seek to grasp the sphere-forming elements of urban space and at the same time include the ideas as well as the social motif structures. Both result in the actions of the city's inhabitants, who weave the invisible symbolic net that lies above the city. The morphology of the city gives us an image of the cultural, social and political structure and history. All together, the ideas, the actions, the forms, result in the material for the discourse of the urban, which comes from the past and will guide us into the future and accompany us incessantly. The lecture deals with a wide range of topics: city as an idea, anthropology of settlement, transition zones, sacred and profane spaces, modern city, connection between urban morphology and society, urbanity, integration. Famous thinkers from the city of Charles Baudelaire, Walter Benjamin, Georg Simmel and Henri Lefebvre, Lewis Mumford to contemporary sociologists and philosophers such as Richard Sennett and Peter Sloterdijk will also be discussed.
