In the first part of the article, the author substantiates the importance of philosophical communication as a kind of dependent variable that does not have an independent meaning without pointing to something else through which the philosophy itself (often negatively and non-reflectively) defines. We are talking about global centers of “systemic” communication (politics, science, religion, etc.), imposing their observations on other communities. It is argued that the priority of philosophical communication is justified by the ability to carry out “universal observations”, which is deprived of all other communication systems.In the second part of the article, the methodological question is first solved about the possibility of explaining a number of phenomena (communications, observations), for which no indication of external factors justifying their existence is required. It is proved that the description and explanation of such phenomena is possible on the way of formulating “significant tautologies” (Peter Railton). Using this method, the author carries out a meaningful deployment of the significant tautology “philosophy is only philosophy” and substantiates that philosophy is communication, capable of defining itself in a universal way: through something else and through itself. The author concludes that philosophy can be considered as a communicative system (i.e.,observer), whose mission is to generate a unique product: a universal self-description of modern society, where philosophy combines three fundamental observational abilities: scientific, protest and artistic activity.
