Note 20 — PART X
Reading edition
The division of the results of man’s mental activity into scientific, philosophic, theological, hortatory, artistic, and other groups, is made for convenience of observation. But such divisions do not exist in reality; just as the divisions of the River Volga into the Tver, Nizhigorod, Simbirsk and Saratov sections, are not divisions of the river itself, but divisions we make for our own convenience.
