common presence
common (adj.) c. 1300, “belonging to all, owned or used jointly, general, of a public nature or character,” from Old French comun “common, general, free, open, public” (9c., Modern French commun), from Latin communis “in common, public, shared by all or many; general, not specific; familiar, not pretentious.” rally “shared by all.”
The mun is the source of Latin munia “duties, public duties, functions,” those related to munia “office.”
The term “common presence” is used repeatedly through The Tales—352 times in total. This, most likely, indicates the importance to Gurdjieff of the notion it conveys. Man, irrespective of whether he has achieved unity, can be thought of as having a “common presence”—of being a multitude.
