This dictionary gives readers a unique opportunity to immerse themselves in the language of philosophical practice. This is the result of the work of Russian scientists fruitfully cooperating with foreign colleagues in the field of philosophical practice. The dictionary briefly and thoroughly reveals basic concepts of philosophical practice with reference to foreign sources, which are so little known to the Russian reader. This is a projective dictionary; it is not “final”. This is an invitation to joint creativity for further understanding of philosophical practice. This dictionary is intended for a wide range of readers.
