"... And the mind refuses to accept more faces, more expressions: on every new face you encounter, it prints the old forms, for each one it finds the most suitable mask."

"Su tutte le facce nuove che incontra, imprime i vechhi calchi, per ognuna trova la mschera che s'adatta di piu."

Sorry for writing in English (a rare case where the constraints of technology jamb with those of taste). "La maschera che s'adatta di piu" means just "the most suitable mask" - so it looks like the Hebrew translator has been ad-libbing a bit.
