The article characterizes the Russian philosophical language as a special type of the language of science. The issue of the relationship between language of philosophy and the philosophy of language is considered. The author argues that the philosophy of language deals with the national language, but not metalanguage of philosophy, thus a special discipline is required to research the philosophical language and its types. However at present such discipline does not exist and is not possible, as the language of philosophy is philosophy itself. Different types of philosophical languages are identified, depending on the type of philosophy, because the language of philosophy corresponds to the subject of philosophy. It is concluded that Russian philosophy is more inclined to artistic philosophical language as Russian philosophy tends to literature from which it is born. In this respect a very important question arises about the translation from the literary language to the philosophical one emerging as a result of this translation.
