Nostalgia as an existential in the focus of the human consciousness problem and urban philosophy

The article deals with the language variability in philosophy and the connected with this variability perception of the problem of human consciousness in the context of the city as a phenomenon of philosophical reflection. We have analyzed the characteristics of two types of philosophical tradition - metaphysics and existential phenomenology and revealed the differences between the two languages of philosophy based on their fundamental features. The basic language for metaphysics is logical-categorical and for existential phenomenology - existential one. This difference in languages influences the subject of philosophy: metaphysics defines the city as a context of human existence in space, time, ergonomics and design categories; existential-phenomenological approach to the problem of human consciousness within the city is based on nostalgia existential, which has two dimensions - temporality and spatiality. Our research has shown that existential approach to the problem of human consciousness within the city is insufficiently developed in modern philosophy, although it is very prospective.
